May in the Garden—A To Do List

This guide is tailored for the western valleys of Oregon and Washington

YOU can help to make the world a better, a more friendly, loving and beautiful place by being a good steward of the spot on this earth, your garden, that you have been given the privilege of borrowing for a time. It is our hope that the following to-do list will help you to do just that.

Nathan, the Treevangelist, urges you to treat your spot on this planet like your own personal Garden of Eden. May it become your personal paradise. This is your divinely mandated responsibility.  Your trees, shrubs, flowers and the wildlife in your yard will pay you back as they express their smiling appreciation to you and yours by radiating their love, joy and beauty bursting forth with vibrant and verdant life. Below is a to-do list to help fulfill this mission.

The newcomers to this region may be wondering what’s with all the rain this year. News flash! And this will come as no surprise to Pacific Northwest natives, but this is typical weather for the western coastal areas and valleys of the northwest Oregon and Washington. Okay, you’re right. This year has been a little wetter than usual. After all, the Portland area recorded well over five inches of rain—a new record. But this is a really good thing. We’re about the only region in the western U.S. that’s not currently in drought conditions, and that’s a mega-blessing! Everywhere south and east of here is still in moderate to severe drought mode. So enjoy that liquid sunshine which will mean a more lush and greener environment, fewer forest fires, less tree die off, and healthier and happier trees and plants everywhere, since they will be less susceptible to drought and pest stress. And finally, more rain means lower irrigation bills us all.  Yay! That’s awesome new, is it not? And this has all been brought to you by our friend, The Rain.

Tree and Shrub Care

  • Mulch. Apply two to three inches of mulch around all trees and ornamental shrubs. This helps to fertilize the plants and feed the soil, and also protects them against weed growth and loss of water when the warmer  weather returns.
  • Pine tree pruning. Don’t do major pruning of pine trees during the growing season, since this attracts sequoia pitch moth infestation.
  • Pruning of large trees. Most trees in the temperate western valleys of Oregon and Washington can be pruned anytime of the year. If you’re not sure what to do, or how to do it, call Good News Tree Service, Inc. for a consultation, pruning lessons or to have them do the pruning for you.
  • Prune fast growing ornamental shrubs that are beginning to look shabby. You may need to prune them again in the early summer for a more neat and manicured look. 
  • Reparative pruning. Repair winter damaged to trees and shrubs.
  • Rhododendrons. Remove old blooms (called “dead heading”). Though it  looks better aesthetically to remove the dead blooms, it doesn’t hurt the plants to leave them on.
  • Tree and shrub removal and stump grinding can be done all year long. 
  • Tree inspections. Have an ISA Certified Arborist with an ISA Tree Risk Assessment Qualification (like Good News Tree Service, Inc.) inspect your large trees for the potential of failure due to weak root systems and defects in trunks and branches. This can be done anytime of the year.
  • Water trees and shrubs as necessary, even before the summer heat starts. This geographical region has entered a period of erratic rain patterns, so even during the typically consistent rainy winter and spring seasons, due to the long periods of dry weather, some tree and shrubs will need extra water. Vigilance is the key. Watch your plants for signs of drought stress, and then give them a drink of water as needed.

Plant Health Care

Good News Tree Service, Inc. provides full plant health care services as listed below.

  • Apple scab on ornamental crabapple and fruiting apple trees. The first visible symptoms occur on leaves in spring as pale, yellowish, water-soaked spots the size of a pinhead. These enlarge, becoming darker and smoky in appearance, later taking on an olive shade and ultimately a brownish black color. Spots may be any shape but are frequently circular. Young infections often show a radiating spread of fungal tissue through the leaf, and such areas later appear as irregular, brown-colored infections. Diseased leaves can be curled and distorted and often drop early. This fungal disease can also move into the fruit to produce a scabby effect, hence the name “apple scab.” Several fungicidal sprays are required to control this disease just prior to flowering and after flowering. 
  • Arborvitae twig blight. Spray in the spring and early summer when new growth starts at two week intervals. 
  • Bronze birch borer. Begin treating in mid-May through June. This is the only time of year that this beetle can be effectively controlled.
  • Cherry leaf spot. Spray cherry trees for leaf spot. Apply first spray at petal fall and two weeks later.
  • Cherry tree brown rot Blossom blight (Monilinia fructicola). Make 3 foliar applications starting at bud break and at 14 day intervals.
  • Coryneum blight (shot hole fungus) or cherry leaf spot. This leaf blight affects ornamental and flowering cherry, plum and prune trees. Spray at petal fall, shuck fall and two weeks later.
  • Deep root fertilization. Trees and ornamental shrubs—deep root fertilize to promote lush, healthy-looking and vigorous crown growth. Urban soils tend to lacking in many of the nutrients that trees and shrubs need to survive. Many are malnourished or are starving to death, which is why they don’t look radiantly healthy are struggling with pest issues. Deep root fertilization helps to promote healthy-looking and pest-resistant trees and shrubs. The best time of the year to do this is in the spring and fall.
  • Dogwood Anthracnose. Spraying with a fungicide at bud break and continue at 10 to 14 day intervals. 
  • Leaf Blights. Spray trees and shrubs for fungal leaf diseases (e.g. powdery mildew, leaf blights, dogwood anthracnose, needle blights, etc.).
  • Monitor trees and shrubs for insect pests. Piercing and sucking plant pests (e.g. aphids, lacebugs, scales, weevils, mites, etc.) are now out and active. If major infestation occurs, plan a course of action to treat your trees and shrubs against these pests. Small numbers of piercing and sucking insects are not harmful to plants. In fact, they provide food for the beneficial, predatory insects that feed on them. To control harmful insects, one can apply systemic insecticides against piercing sucking insects (aphids, lacebugs, scales, weevils, etc.) via soil injections (one treatment gives season-long control). If applied according to label directions, this will kill only the harmful and not beneficial insects.
  • Photinia leaf spot. Spray with a fungicide as new shoots are developing at 30 day intervals.
  • Pine dothistroma needle blight. Apply fungicide at just before bud break and a few weeks later according.
    Powdery Mildew. Apply a fungicides as soon as symptoms appear. Best efficacy occurs if used before symptoms appear. Use fungicide at 7 to 14 day intervals, or more often if conditions warrant it. If a plant is known to have had powdery mildew previously,  apply as buds start to open.
  • Spider mites will start to become active as the weather warms. Systemic insecticides are available against this pest.
  • Tent Caterpillar. Apply systemic pesticide for season-long control.
  • Verticillium Wilt. Soil drench in the spring. Maples are especially susceptible to this fungal root disease as are cherries and plums.
  • Willow Twig Blight (scab). Apply two or three applications beginning when new leaves first appear at 10 to 14 day intervals.

Elsewhere in the Garden

  • Annual and perennial plants. May is when your local garden centers begin selling both annual and perennial plants with colorful leaves and flowers to add splashes of color to your garden. Annuals typically are plants that need to be planted in the garden each year, since they are unlikely to survive the colder temperatures of winter. Some annuals like California poppy and violets will automatically reseed themselves and come up again in the spring. Most annuals, however, need to be replanted each spring. Popular colorful annual plants include begonia, coleus, cosmos, forget-me-not,  geraniums, impatiens, marigold, nasturtium, pansy, petunia, snapdragons, sunflower, sweet william, violets and zinnia. Perennials are plants whose tops die back each winter, but come back from the roots in the spring. Common perennial plants that will add color to your garden include alstromeria, bleeding heart, carnation, calendula, clematis, columbine, chrysanthemum, coral bells (heuchera), daisy, daffodil, dahlia, daylilly, fuchsia (hardy varieties), gladiola, hellebore, hosta, iris, lavender, lupine, peony, primrose, red hot poker, tulip and yarrow.
  • Birds. Continue to keep your bird feeders full. Why? Even though we’re now past the winter season and there is more food available for the birds, having these feathery friends frequent your garden serves several purposes. During dry spells, keep your bird bath watering hold full of fresh water. Caring for the local wild birds brings life and excitement to your backyard by turning it into a bird-friendly sanctuary. The birds will thank you for your generosity by providing you with hours of entertainment, and by eating insect pests that harm your ornamental trees and shrubs. You can find excellent bird care products and advice from knowledgeable and caring professionals at your local Backyard Bird Shop.
  • Fertilization. Fertilize your ornamental shrubs with a slow release fertilizer. If the shrubs have a layer of barkdust or other mulch around them, rake the mulch away and apply the fertilize to the bare dirt, so that it actually reaches the plant’s root zone. 
  • Ivy on trees. Though a decorative evergreen ground cover and climbing vine, English ivy is considered an invasive species, since it spread so rapidly and birds disperse its seeds everywhere. It will soon take over your yard and garden if not contained. Even worse, it grows up into trees, and even though it is not parasitic in that it takes nutrients from its host tree, it can eventually choke smother a tree foliage depriving the leaves of life-giving sunlight. The loss of foliage can stress and even eventually kill a trees. This is why it is imperative to cut ivy away from the base of your trees. The ivy climbing up into a tree can be killed simply by cutting through its stalks at the base of the tree. This can be done any time of the year.
  • Mulching. Apply two to three inches of mulch (e.g. bark dust, garden compost or wood chips) on all of your shrub beds. Covering bare dirt areas in your yard with mulch helps to prevent soil compaction from rains, and weed growth, and helps to enrich our heavy clay soils.
  • Slugs. Put slug bait around your flowers and tender perennials like primroses and hostas.
  • Tree and shrub planting. This is a good time of the year to plant trees and shrubs. Visit your local nursery and select your favorite ornamental shrubs and shade trees. After planting your new shrubs, just make sure that you water them well immediately and regularly subsequently for the first two or three summers until their roots get established. During warm weather (in the 60s to low 80s), deep root water once per week. During hot weather (mid-80s and higher) deep root water at least twice per week.
  • Vegetable garden. Start making plans for your vegetable garden. Once the soil has dried out, you can begin working it for planting our veggies. Usually this will occur in late April or early May and sometimes later depending on the weather. The earlier you plant, the sooner you’ll be feeding on delicious veggies from your own garden! 
  • Watering. Water and fertilize annuals and perennial flowers. The hotter the weather, the more water they will need. Flowers in pots and hanging baskets dry out especially quickly, and so need watering every day or two.

Care of Roses

  • Dealing with rose pests. Spray or treat roses with a fungicide as needed preventively to insure protection against fungal pathogens such as black spot, powdery and cottony mildew, rust and spot anthracnose. Apply a fungicide only after the rose has put out several inches of new growth. Excellent choices of both organic and inorganic fungicides are available at your local garden center or nursery. Some fungicides require spraying in the early spring as the new growth is emerging. Major plant pests include mites, aphids, thrips, rose slugs, leaf rollers, rose midge, spittle bug and sawfly. Determine what pest or disease your rose has, do some research online if necessary to ascertain this, and then visit your local garden center or nursery to find the right product for the job. Always read and follow all label directions. It’s the law! 

Lawn Care

  • Overseed bare spots. When the weather begins to warm up, but are not too hot and there is still regular rainfall, and when the grass begins to grow, it is an excellent time to overseed bare or thin spots in your yard. Fall is the best time of the year to reseed bare areas of your lawn, while spring is the second best time.
  • Start mowing. Begin to mow your grass every week or as needed. For the best results, do not remove more than one-third of the top growth of  your grass at a time. Grass can be kept shorter during cooler weather, but when the hot summer weather begins, it is less stressful on the grass to allow it to remain at about two to three inches tall. This also helps the grass to choke out any weeds that might try to grow up through it.
  • Weed control. Annual weeds, such as crabgrass, grow from seed each spring. A well-timed application of preemergence herbicide to stop them from growing is called for at this time of the year. A good guideline is to spread the preemergence herbicide as forsythia blooms in your area start to drop.
  • Fertilization. Feeding your lawn at least couple of times a year is a must. One fertilization in the spring and one again in the fall is the minimum requirement to maintain a healthy lawn. 

April in the Garden—A To Do List

Below is a to-do list to help fulfill this mission.

Let the show begin starting with the flora fireworks! This month, the garden is popping with life as the naked deciduous trees and shrubs don their seasonal leafy attire and celebrate the arrival of spring as they burst forth with all those pent up life-force juices as the stars of the plant world prance onto the garden stage to impress us with their performance. They’re beginning to flauntingly parade themselves down the garden’s catwalk with their fantasmic plethora and rainbowic panoply of star-spangled colors from the lowly perennial primrose to the ostentatiously regal Mount Fuji cherry tree. Meanwhile, the birds are serenading us with their twitterpational love songs, and even the croaking frogs with their basso profundo tones are jumping into the garden’s three ring circus and trying to steal the show. So what more can be said? It’s time to get up and get out there and to join choir by donning your garden shoes and gloves and picking up your handy tools as nature’s orchestra play its halleluYah chorus!

Tree and Shrub Care

  • Fruit tree pruning. It’s time to finish pruning your fruit trees for fruit production. Also finish pruning your grapes, cane and trailing berries once the threat of major frost is past. Fruit trees can be pruned any time of the year, but it’s best not to prune them while they have flowers or fruit on them for fear of destroying part of your fruit harvest.
  • Finish planting your fruit trees. By getting them in the ground in the winter or early spring, they’ll have time to acclimate to their new home before summer comes. 
  • Mulch. Apply two to three inches of mulch around all trees and ornamental shrubs. This helps to fertilize the plants and feed the soil, and also protects them against weed growth and loss of water when the warmer  weather returns.
  • Pine tree pruning. Finish pruning coast/shore pines (Pinus contorta) and Scotch/Scots pines (Pinus sylvestris). These two pines are especially susceptible to the sequoia pitch moth whose larvae burrow into the tree trunks during the growing season (April through September) causing the trees to exude large amounts of unsightly pitch globules. While this seldom kills the tree, the bleeding of sap is not good for the overall health and vigor of the tree. It is advisable, therefore, not to prune these pine trees during the growing season, since the pruning cuts attract the moth, which then lays eggs on the tree, which hatch into tree-burrowing larvae. Pruning should be done on your pines from November to March.
  • Plant or transplant trees and shrubs. Early spring is still a good time to plant or transplant ornamental trees and shrubs. Cooler weather means less transplant shock to the plants, and over  the winter and spring, they will have time to begin to acclimate to their new environment before the stress of the next summer season occurs.
  • Pruning of large trees. Most trees in the temperate western valleys of Oregon and Washington can be pruned anytime of the year. If you’re not sure what to do, or how to do it, call Good News Tree Service, Inc. for a consultation, pruning lessons or to have them do the pruning for you.
  • Pruning of ornamental shrubs. Early in the spring before a lot of new growth starts is a good time to do major pruning (called heading back) of rhododendrons (or rhodies) and other similar ornamental shrubs back to latent buds in trunks and stalks. Do this before spring growth begins in the near future. Prune fast growing ornamental shrubs that are beginning to look shabby. You may need to prune them again in the early summer for a more neat and manicured look. 
  • Reparative pruning. Repair winter damaged to trees and shrubs.
  • Tree and shrub removal and stump grinding can be done all year long. 
  • Trees. Have an ISA Certified Arborist with an ISA Tree Risk Assessment Qualification (like Good News Tree Service, Inc.) inspect your large trees for the potential of failure due to weak root systems and defects in trunks and branches. This is best done when the leaves are off the trees.

Plant Health Care

Good News Tree Service, Inc. provides full plant health care services as listed below.

This fungal disease can also move into the fruit to produce a scabby effect, hence the name “apple scab.” Several fungicidal sprays are required to control this disease just prior to flowering and after flowering. 
  • Arborvitae twig blight (Thuja occidentalis). Spray in the spring and early summer when new growth starts at two week intervals. 
  • Birch rust fungus. Occurs on leaves. Spray before symptoms appear on 10 to 14 day intervals—4 apps if infestation is severe.
  • Cherry tree brown rot blossom blight (Monilinia fructicola). Make 3 foliar applications starting at bud break and at 14 day intervals.
  • Coryneum blight (shot hole fungus) or cherry and plum leaf spot. This leaf blight affects ornamental and flowering cherry, plum and prune trees. Apply fungicide in the spring at flower petals fall, shuck fall and two weeks later.
  • Crabapple leaf blight. Apply fungicide as the leaf clusters are just opening up and make several more applications subsequently as per label directions.
  • Deep root fertilization. Trees and ornamental shrubs—deep root fertilize to promote lush, healthy-looking and vigorous crown growth. Urban soils tend to lacking in many of the nutrients that trees and shrubs need to survive. Many are malnourished or are starving to death, which is why they don’t look radiantly healthy are struggling with pest issues. Deep root fertilization helps to promote healthy-looking and pest-resistant trees and shrubs. The best time of the year to do this is in the spring and fall.
  • Dogwood anthracnose. Begin spraying with a fungicide at bud break and continue at 10 to 14 day intervals. 
  • Dormant spraying of fruit trees. Continue fungal sprays until after flower petals have dropped off.
  • Magnolia bacterial blight. Apply one fungal spray in fall and twice in spring near budbreak.
  • Lawns. Fertilize lawns.
  • Leaf blights. Spray trees and shrubs for fungal leaf diseases (e.g. powdery mildew, leaf blights, dogwood anthracnose, needle blights, etc.).
  • Monitor trees and shrubs for insect pests. When piercing and sucking plant pests (e.g. aphids, lacebugs, scales, weevils, mites, etc.) hatch varies each year depending on when the warmer weather begins. Usually, hatching of plant pests begins from early to late April. When consistent warm weather begins to occur, start monitoring plants for insect nymphs and adults. If necessary, plan a course of action to treat your trees and shrubs against these pests.
  • Pear rust. Apply fungicide in early spring about bloom time as the orange fungal telium (pl. telia) begin to appear.
  • Photinia leaf spot. Spray with a fungicide as new shoots are developing at 30 day intervals.
  • Piercing-sucking insects. Continue applying systemic insecticides against piercing sucking insects (aphids, lacebugs, scales, weevils, etc.) via soil injections (one treatment gives season-long control). 
  • Pine dothistroma needle blight. Apply fungicide at just before bud break and a few weeks later.
  • Powdery mildew. Apply a fungicides as soon as symptoms appear. Best efficacy occurs if used before symptoms appear. Use fungicide at 7 to 14 day intervals, or more often if conditions warrant it. If a plant is known to have had powdery mildew previously,  apply as buds start to open.

  • Tent caterpillar. Apply systemic pesticide for season-long control.
  • Verticillium wilt. Soil drench in the spring. Maples are especially susceptible to this fungal root disease as are cherries and plums.
  • Willow twig blight (scab). Apply two or three applications beginning when new leaves first appear at 10 to 14 day intervals.

Elsewhere in the Garden 

  • Feed the birds. Continue to keep your bird feeders full. Why? Even though we’re now past the winter season and there is more food available for the birds, having these feathery friends frequent your garden serves several purposes. During dry spells, keep your bird bath watering hold full of fresh water. Caring for the local wild birds brings life and excitement to your backyard by turning it into a bird-friendly sanctuary. The birds will thank you for your generosity by providing you with hours of entertainment, and by eating insect pests that harm your ornamental trees and shrubs. You can find excellent bird care products and advice from knowledgeable and caring professionals at your local Backyard Bird Shop. 
  • Ferns. Cut off last year’s fronds from ferns as new fiddleheads begin to emerge.
  • Flower planting. Begin planting annual and perennial flowers.
  • English ivy control. Though a decorative evergreen ground cover and climbing vine, English ivy is considered an invasive species, since it spread so rapidly and birds disperse its seeds everywhere. It will soon take over your yard and garden if not contained. Even worse, it grows up into trees, and even though it is not parasitic in that it takes nutrients from its host tree, it can eventually choke smother a tree foliage depriving the leaves of life-giving sunlight. The loss of foliage can stress and even eventually kill a trees. This is why it is imperative to cut ivy away from the base of your trees.

Usually this will occur in late April or early May and sometimes later depending on the weather. The earlier you plant, the sooner you’ll be feeding on delicious veggies from your own garden! 

Rose Care

  • Fertilization. Roses are flowering machines and need regular fertilizing. They require three fertilizations per year. First in April, then at the end of June, and finally in late August. Fertilize roses with something like a 15-10-10, 20-20-20 or 30-15-15 fertilizer. Use a variety of types of fertilizers for best results.
  • Pests. Spray or treat roses with a fungicide as needed preventively to insure protection against fungal pathogens such as black spot, powdery and cottony mildew, rust and spot anthracnose. Apply a fungicide only after the rose has put out several inches of new growth. Excellent choices of both organic and inorganic fungicides are available at your local garden center or nursery. Some fungicides require spraying in the early spring as the new growth is emerging. Major plant pests include mites, aphids, thrips, rose slugs, leaf rollers, rose midge, spittle bug and sawfly. Determine what pest or disease your rose has, do some research online if necessary to ascertain this, and then visit your local garden center or nursery to find the right product for the job. Always read and follow all label directions. It’s the law!

Lawn Care (April or May)

  • Overseed bare spots. When the weather begins to warm up, but are not too hot and there is still regular rainfall, and when the grass begins to grow, it is an excellent time to overseed bare or thin spots in your yard.

March in the Garden—A To Do List

This guide is tailored for the western valleys of Oregon and Washington. 

YOU can help to make the world a better, a more friendly, loving and beautiful place by being a good steward of the spot on this earth, your garden, that you have been given the privilege of borrowing for a time. It is our hope that the following to-do list will help you to do just that.

Nathan, the Treevangelist, that is, the preacher of the good news about the beauty and benefit of trees, urges you to treat your spot on this planet like your own personal biblical Garden of Eden. May it become your personal paradise and refuge from this hectic and stressful world. The care of your garden is your divinely mandated responsibility.  Your trees, shrubs, flowers and the wildlife in your yard depend on your vigilant and loving care, and they will pay you back as they express their smiling appreciation to you and yours by radiating their love, joy and beauty bursting forth with vibrant and verdant life. Below is a to-do list to help fulfill this godly mission.

It seems to this Pacific Northwest native that this winter has been more normal in terms of rainfall amounts and temperatures than several of our previous years. The rain, so far, has been regular, which is a welcome relief from the alarmingly irregular rain patterns and drought conditions of the past few years. So we thank Heaven for this, for it is the rain that keeps our northwest region the luscious garden and the envy of outsiders for which it is well-known. On a personal note, I have traveled to some 22 countries on four continents and half of the U.S. states including Alaska and Hawaii. I also spent a year living in the mountains of Switzerland at the foot of its famous Alps. So I have seen a lot of this earth’s natural splendor, yet no place that I have seen to date has more natural beauty and diversity, in my opinion, than our Pacific Northwest. So let’s all do our part to keep it this way!

Tree and Shrub Care

  • Fruit tree pruning. Prune your fruit trees for fruit production. You can also prune grapes, cane and trailing berries once the threat of major frost is past.
  • Plant fruit trees. At this time of the year, bare root fruit trees can be purchased inexpensively at your local garden center. It is imperative to plant them while they are still in their dormant state and before their buds start to swell just before bloom time.
  • Plant trees and shrubs. Now is an excellent time to plant all kinds of trees and shrubs in the garden, while the weather is cool and the plants are still dormant. This is also a good time to reduce the height of overgrown fruit trees, since they are likely to produce fewer water sprouts now then when pruned in the spring.
  • Severe pruning of some ornamental shrubs. Now is an excellent time to do major pruning (even back to bare stocks) of certain overgrown evergreen shrubs before they start their new growth in the next month or so. Shrubs that can be pruned back severely include rhododendron (or rhody), camellia, andromeda or lily of the valley shrub, Japanese holly, laurel and photinia to name a few. Not all shrubs can take such severe pruning, so know the growth habits of your plant before doing so. When you prune, make sure that you cut back to a bud point or a branch union. Do not cut internodially or between buds points or leaf whirls.
  • Mulch. Apply two to three inches of mulch around all trees and ornamental shrubs. This helps to fertilize the plants and feed the soil, and also protects them against weed growth and loss of water when the warmer  weather returns.
  • Pine tree pruning. Prune coast or shore pines (Pinus contorta) and Scotch or Scots pines (Pinus sylvestris). These two pines are especially susceptible to the sequoia pitch moth whose larvae burrow into the tree trunks during the growing season (April through September) causing the trees to exude large amounts of unsightly pitch globules. While this seldom kills the tree, the bleeding of sap is not good for the overall health and vigor of the tree. It is advisable, therefore, not to prune these pine trees during the growing season, since the pruning cuts attract the moth, which then lays eggs on the tree, which hatch into tree-burrowing larvae. Pruning should be done on your pines from November to March.
  • Plant or transplant trees and shrubs. Winter is a good time to plant or transplant ornamental trees and shrubs. Cooler weather means less transplant shock to the plants, and over  the winter and spring, they will have time to begin to acclimate to their new environment before the stress of the next summer season occurs.
  • Pruning of large trees. Winter is a great time to do aesthetic and structural pruning of deciduous trees and shrubs, since the structure or architecture of the plant is clearly visible making aesthetic pruning easier than when plants are foliated. Structural defects, which can cause tree failure, are more easily spotted as well. Also remove of dead wood, and pruning to reduce hazards. If you’re not sure what to do, or how to do it, call Good News Tree Service, Inc. for a consultation, pruning lessons or to have them do the pruning for you.
  • Reparative pruning. Repair winter damaged to trees and shrubs.
  • Roses. The best time to prune roses is after the threat of major frost is past.
  • Tree and shrub removal and stump grinding can be done all year long. 
  • Trees. Have an ISA Certified Arborist with an ISA Tree Risk Assessment Qualification (like Good News Tree Service, Inc.) inspect your large trees for the potential of failure due to weak root systems and defects in trunks and branches. This is best done when the leaves are off the trees.

Plant Health Care

These are some of the large trees that Good News Tree Service, Inc. helps to care for. These ancient native oak trees were stressed and in danger of dying before we started treating them. Now they are healthy and flourishing.

Good News Tree Service, Inc. provides full plant health care services as listed below.

  • Apple scab on ornamental crabapple and fruiting apple trees. The first visible symptoms occur on leaves in spring as pale, yellowish, water-soaked spots the size of a pinhead. These enlarge, becoming darker and smoky in appearance, later taking on an olive shade and ultimately a brownish black color. Spots may be any shape but are frequently circular. Young infections often show a radiating spread of fungal tissue through the leaf, and such areas later appear as irregular, brown-colored infections. Diseased leaves can be curled and distorted and often drop early. This fungal disease can also move into the fruit to produce a scabby effect, hence the name “apple scab.” Several fungicidal sprays are required to control this disease just prior to flowering and after flowering.
  • Arborvitae Berckmann’s Blight (Platycladus orientalis). Spray in the fall (late Sept. and early Oct., and again in early Nov. Spray again in early spring (Feb to Mar) if disease is severe. 
  • Cherry Tree Brown Rot Blossom Blight (Monilinia fructicola). Make 3 foliar applications starting at bud break and at 14 day intervals. 
  • Coryneum Blight (Shot Hole Fungus) or Cherry & Plum Leaf Spot. This leaf blight affects ornamental and flowering cherry, plum and prune trees. Apply fungicide in the spring at flower petals fall, shuck fall and two weeks later.
  • Crabapple Leaf Blight. Apply fungicide as the leaf clusters are just opening up and make several more applications subsequently as per label directions.
  • Deep Root Fertilization. Deep root fertilize your trees and shrubs just prior to or as new leaves begin to emerge. Apply when soils are not super-saturated with rain, so that the fertilizer isn’t washed away from plants’ roots after applications is made.
  • Dormant Spraying of Fruit Trees. Apply dormant sprays against insects and fungi.
  • Lawns. Fertilize yellowing lawns.
  • Leaf Blights. Spray trees and shrubs for fungal leaf diseases (e.g. powdery mildew, leaf blights, dogwood anthracnose, needle blights, etc.).
  • Magnolia Bacterial Blight. Apply one spray in fall and twice in spring near budbreak. 
  • Monitor trees and shrubs for insect pests. When piercing and sucking plant pests (e.g. aphids, lacebugs, scales, weevils, mites, etc.) hatch varies each year depending on when the warmer weather begins. Usually, hatching of plant pests begins from early to late April. When consistent warm weather begins to occur, start monitoring plants for insect nymphs and adults. If necessary, plan a course of action to treat your trees and shrubs against these pests.
  • Piercing-Sucking Insects. Begin applying systemic insecticides against piercing sucking insects (aphids, lacebugs, scales, weevils, etc.) via soil injections (one treatment gives season-long control). 
  • Photinia leaf spot. Spray a fungicide early in February of four applications at two week intervals afterwards. Early spray is key to controlling this fungus.
  • Powdery Mildew. Apply a fungicides as soon as symptoms appear. Best efficacy if used before symptoms appear. Use fungicide at seven to fourteen day intervals, or more often if conditions warrant it. If a plant is known to have had powdery mildew previously,  apply as buds start to open.
  • Tent Caterpillar. Apply systemic pesticide for season-long control.
  • Verticillium Wilt Fungal Disease. Apply a soil in the fall and spring.

Elsewhere in the Garden

This is a gandoderma lucidum or fungal conk that is growing on the side of an oak tree at its base. Though beautiful in appearance, this polymorph or bracket fungus can cause rot on the inside of live trees.
  • Ferns. Ferns are popular ornamental plant that grow natively in the wilds of the Pacific Northwest. They require minimal care and thrive in shaded areas. To keep ferns looking beautiful throughout the coming season, a little manicuring is necessary. This involves cutting off last year’s fronds from ferns as new fiddleheads begin to emerge. 
  • Slug control. Put slug bait around winter flowers. Though the weather may be cold, slugs are still active.
  • Clean up. Rake and dispose of ornamental tree leaves, or better yet, compost them and then spread the decomposed leaves back onto your shrub beds as a mulch next year.
  • Mulch all of your shrub beds. Put a two to three inches of mulch (e.g. bark dust, garden compost or wood chips) around perennials and other plants that might be sensitive to subfreezing weather.  Also, spread a fresh layer of mulch (e.g. bark dust, garden compost or wood chips) on all the bare dirt areas in your yard to prevent soil compaction from rains, to prevent weed growth and to enrich and help to condition your heavy clay soils.
  • English ivy control. Though a decorative evergreen ground cover and climbing vine, English ivy is considered an invasive species, since it spread so rapidly and birds disperse its seeds everywhere. It will soon take over your yard and garden if not contained. Even worse, it grows up into trees, and even though it is not parasitic in that it takes nutrients from its host tree, it can eventually choke smother a tree foliage depriving the leaves of life-giving sunlight. The loss of foliage can stress and even eventually kill a trees. This is why it is imperative to cut ivy away from the base of your trees. The ivy climbing up into a tree can be killed simply by cutting through its stalks at the base of the tree. This can be done any time of the year.
  • Feed the birds. Dutifully maintain your bird feeders. As winter comes, birds have a harder time finding food.  This includes both seed and suet feeders. During dry spells, keep your bird bath watering hold full of fresh water. Caring for the local wild birds brings life and excitement to your backyard by turning it into a bird-friendly sanctuary. The birds will thank you for your generosity by providing you with hours of entertainment, and by eating insect pests that harm your ornamental trees and shrubs. Remember to feed your local humming birds that overwinter in our region. If possible, fill your humming bird feeders with a syrup that contains only 100 percent sugar (e.g. sucrose or dextrose) minus any artificial sweeteners, red dyes and other chemicals. Your birds will be healthier for it. You can find excellent bird care products and advice from knowledgeable and caring professionals at your local Backyard Bird Shop.

Care of Roses

  • Prune roses. Mid to late-February  or early March (or after the threat of hard frosts have passed is the time to prune roses for health and bloom potential. Remove dead, weak and spindly canes. Leave only the strongest and healthiest canes that are equally spread apart thus giving them good air circulation to reduce the potential spread of fungal pathogens that cause leaf diseases. An open spacing pattern of the canes also provides ample room for the blooms to grow without crowding each other. Make pruning cuts slightly above an outward-facing bud. Endeavor to prune rose bushes into an upward and outward vase-shaped form.
  • Late winter-early spring. Now is the time to plant roses. Plant them in full sun. Roses don’t do well in shade and need at least six hours of sun per day especially in the summer. Morning sun is preferable to dry off the dew. Add plenty of mulch, manure or other soil amendment into the soil when planting. Choose pest and disease resistant rose varieties for best, long term results.

Lawn Care March Through May

  • Feed the wild birds. Attracting wild birds to your garden is an excellent way to naturally control harmful insects. Allow wild birds such as starlings to peck at your grass as they are feeding on insects that are harmful to your lawn.
  • Irrigation systems. Check your irrigation system well before the warm weather starts to ensure that there are no broken pipes, faulty sprinkler heads or broken risers. Check sprinkler heads for adequate coverage and adjust or replace as necessary. Check your timer to make sure it is functioning so that expensive water wastage does not occur. Have your irrigation backflow prevention device tested. In some cities, this a yearly requirement.
  • Get your mower ready. Perform mower maintenance. Take your mower into repair shop to perform annual engine maintenance and blade sharpening. Do it early in the season when the repair shops are not busy and to avoid the spring rush, so that you will not be delayed in mowing your grass in the spring.
  • Dethatch your lawn. Once your lawn has dried out and it is not excessively wet—usually in April or May—dethatch your lawn of old roots and stems. Rake and remove the thatch. Lawn dethatchers can be rented  or your gardener can perform this service.
  • Aerate compacted soil. Lawn soil becomes compacted due to human and pet traffic as well as rainfall thus hindering water and fertilizer penetration and the growth of grass roots. This is why it is wise to aerate your lawn occasionally—preferably annually—for the best looking and most healthy lawn. Lawn aerators can be rented or your gardener can perform this service.
  • Remove perennial weeds. Once the grass starts to grow and on a dry day, spot treat weeds with an herbicide. Read and follow all label directions including wearing the recommended personal protection equipment (or PPE) when applying chemicals herbicides. At any time of the year, you can dig out the weeds by hand.

I took the following photos in a recent trip to the world-famous Portland Japanese Gardens where we take field trips to learn about ornamental shrub pruning styles and techniques.

February in the Garden—A To List

This guide is tailored for the western valleys of Oregon and Washington. 

YOU can help to make the world a better, a more friendly, loving and beautiful place by being a good steward of the spot on this earth, your garden, that you have been given the privilege of borrowing for a time. It is our hope that the following to-do list will help you to do just that.

Nathan, the Treevangelist, urges you to treat your spot on this planet like your own personal Garden of Eden. May it become your personal paradise. This is your divinely mandated responsibility.  Your trees, shrubs, flowers and the wildlife in your yard will pay you back as they express their smiling appreciation to you and yours by radiating their love, joy and beauty bursting forth with vibrant and verdant life. Below is a to-do list to help fulfill this mission.

As the days begin to lengthen, the cold temps begin to inch upward, and the sun begins to peak out from behind the clouds a tiny bit more, guess what? Heat and light incubate life. Plant buds are beginning to swell, and a few hardy early-bird flowers are beginning to pop out of the cold ground. Rejoice as the earth begins to awaken with a new flourish of life, and take a moment to walk around your personal domain and notice as the inexorable and reassuringly predictable cycles of plant-life rebirths once again despite the crazy, erratic, capricious and often malevolent machinations of many humans everywhere. Never forget that while the outlook may be a bit crazy, but the uplook, heavenward, is always great.

Tree and Shrub Care

  • Fruit tree pruning. Now is the time to prune your fruit trees for fruit production. You can also prune grapes, cane and trailing berries once the threat of major frost is past.
  • Plant fruit trees. Not only is this a good time to plant bare-root fruits trees, which you can purchase now at many garden centers, but it’s an excellent to plant all kinds of trees and shrubs in the garden, while the weather is cool and the plants are still dormant. This is also a good time to reduce the height of overgrown fruit trees, since they are likely to produce fewer water sprouts now then when pruned in the spring.
  • Yard clean up. Rake and dispose of ornamental tree leaves, or better yet, compost them and then spread the decomposed leaves back onto your shrub beds as a mulch next year.
  • Mulch. Apply two to three inches of mulch around all trees and ornamental shrubs. This helps to fertilize the plants and feed the soil, and also protects them against weed growth and loss of water when the warmer  weather returns.
  • Pine tree pruning. Prune coast or shore pines (Pinus contorta) and Scotch/Scots pines (Pinus sylvestris). These two pines are especially susceptible to the sequoia pitch moth whose larvae burrow into the tree trunks during the growing season (April through September) causing the trees to exude large amounts of unsightly pitch globules. While this seldom kills the tree, the bleeding of sap is not good for the overall health and vigor of the tree. It is advisable, therefore, not to prune these pine trees during the growing season, since the pruning cuts attract the moth, which then lays eggs on the tree, which hatch into tree-burrowing larvae. Pruning should be done on your pines from November to March.
  • Plant or transplant trees and shrubs. Winter is good time to plant or transplant ornamental trees and shrubs. Cooler weather means less transplant shock to the plants, and over  the winter and spring, they will have time to begin to acclimate to their new environment before the stress of the next summer season occurs.
  • Pruning of ornamental shrubs. Do major pruning (called heading back) of rhododendrons (or rhodies) and other similar ornamental shrubs back to latent buds in trunks and stalks. Do this before spring growth begins in a couple of months.
  • Pruning of large trees. Winter is a great time to do aesthetic and structural pruning of deciduous trees and shrubs, since the structure or architecture of the plant is clearly visible making aesthetic pruning easier than when plants are foliated. Structural defects, which can cause tree failure, are more easily spotted as well. Also remove of dead wood, and pruning to reduce hazards. If you’re not sure what to do, or how to do it, call Good News Tree Service, Inc. for a consultation, pruning lessons or to have them do the pruning for you.
  • Roses. The best time to prune roses is after the threat of major frost is past.
  • Tree and shrub removal and stump grinding can be done all year long. 
  • Hazard tree assessment. Have an ISA Certified Arborist with an ISA Tree Risk Assessment Qualification (like Good News Tree Service, Inc.) inspect your large trees for the potential of failure due to weak root systems and defects in trunks and branches. This is best done when the leaves are off the trees. 
  • Trees and Storms. Storm proof your larger trees. Checking your trees for hazards and then take the appropriate measures to protect your trees from storm damage. After each major weather event, check your trees for damage such as broken or hanging limbs. If you have concerns or questions about your trees, have an ISA Certified Arborist with an ISA Tree Risk Assessment Qualification (like Good News Tree Service, Inc.) inspect your large trees for damage or the potential of failure due to weak root systems and defects in trunks and branches. If you’re not sure about the condition of your trees or even what to look for, call Good News Tree Service, Inc. for a free on-site consultation.

Plant Health Care

Good News Tree Service, Inc. provides many of the plant health care services listed below.

  • Arborvitae Berckmann’s Blight (Platycladus orientalis). Spray in the fall (late Sept. and early Oct., and again in early Nov. Spray again in early spring (Feb to Mar) if disease is severe. 
  • Dormant Spraying of Fruit Trees. Apply dormant sprays against insects and fungi.
  • Lawns. Fertilize yellowing lawns.
  • Piercing-Sucking Insects. Apply systemic insecticides against piercing sucking insects (aphids, lacebugs, scales, weevils, etc.) via soil injections (one treatment gives season-long control). This is a service that Good News Tree Service, Inc. provides. Free price quotes are available upon request.
  • Photinia leaf spot. Spray a four applications of fungicide early in February at two week intervals afterwards. Early spray is key to controlling this fungus.
  • Powdery Mildew. Apply a fungicides as soon as symptoms appear (when the weather begins to warm up). Best efficacy is obtained if used before symptoms appear. Use fungicide at seven to fourteen day intervals, or more often if conditions warrant it. If a plant is known to have had powdery mildew previously,  apply as buds start to open.
  • Tent Caterpillar. Apply systemic pesticide for season-long control.

Elsewhere in the Garden

  • Slug control. Put slug bait around winter flowers. Though the weather may be cold, slugs are still active.
  • Clean up. Rake and dispose of ornamental tree leaves, or better yet, compost them and then spread the decomposed leaves back onto your shrub beds as a mulch next year.
  • Mulch all of your shrub beds. Put a two to three inches of mulch (e.g. bark dust, garden compost or wood chips) around perennials and other plants that might be sensitive to subfreezing weather.  Also, spread a fresh layer of mulch (e.g. bark dust, garden compost or wood chips) on all the bare dirt areas in your yard to prevent soil compaction from rains, to prevent weed growth and to enrich and help to condition your heavy clay soils.
  • Cut English ivy off of the base of trees. (This can be done any time of the year.)
  • Feed the birds. Dutifully maintain your bird feeders. As winter comes, birds have a harder time finding food.  This includes both seed and suet feeders. During dry spells, keep your bird bath watering hold full of fresh water. Caring for the local wild birds brings life and excitement to your backyard by turning it into a bird-friendly sanctuary.

Your birds will be healthier for it. You can find excellent bird care products and advice from knowledgeable and caring professionals at your local Backyard Bird Shop.

Rose Care

  • Prune your roses. The best time to do heavy pruning of roses is after the threat of major frost is past.
  • Anytime of the year. Heavily mulch your roses. Organic mulch (such as wood chips, rotted compost, rotted manure) is the best. While barkdust helps to hold moisture in the soil, it contains little or no nutrients, so it doesn’t feed the soil and thus won’t feed your roses.
  • For more information on the care of roses, go to the Portland Rose Society website at https://www.portlandrosesociety.org/all_about_roses.html. 

Lawn Care

  • Perform mower maintenance. This is a good time to take your mower to repair shop for some annual engine maintenance and blade sharpening. Do it in the winter when the repair shops are not busy and to avoid the spring rush so that you will be ready to mow your grass in the spring.
  • Other lawn care. Avoid walking on extremely soggy or heavily frost-covered lawns to avoid damage to your grass.

November in the Garden—A To Do List

Below is a to do list to help you to do just that.

After an atypically long summer (it started in early June) with record high temperatures and severe drought conditions, with the advent of fall, the climate suddenly turned an abrupt corner and someone upstairs turned on the water spigot. Thank you Lord for answering our prayers!

So the big name stars that are capturing the headlines for this November are Stormy Rain, Falling Leaves and Cool Gray. And I don’t want to hear any complaints from the audience either, because we need these actors to do their thing on the seasonal stage for the greater good that benefits us all. Sermon done…(for now, at least).

Tree and Shrub Care

  • Fruit tree sanitation. To prevent possible spread of leaf diseases, rake up and remove leaves from around the base of fruit trees. 
  • Fruit tree pruning. After the leaves drop is an excellent time to prune trees that are done fruiting and for aesthetics, since wounds will heal more quickly in warmer weather than occurs in winter. This is also a good time to reduce the height of overgrown fruit trees, since they are likely to produce fewer water sprouts now then when pruned in the spring.
  • Storm proof your larger trees. Checking your trees for hazards and then take the appropriate measures to protect your trees from storm damage. If you’re not sure about the condition of your trees or even what to look for, call Good News Tree Service, Inc. for a free on-site consultation.
  • Large trees. After each major weather event, check your trees for damage such as broken or hanging limbs. If you have concerns or questions about your trees, have an ISA Certified Arborist with an ISA Tree Risk Assessment Qualification (like Good News Tree Service, Inc.) inspect your large trees for damage or the potential of failure due to weak root systems and defects in trunks and branches. 
  • Trees—storm issues. With the advent of winter storms and the potential damage that they may inflict upon your trees, have an ISA Certified Arborist with an ISA Tree Risk Assessment Qualification (like Good News Tree Service, Inc.) inspect your large trees for the potential of failure due to weak root systems and defects in trunks and branches. This can be done anytime of the year, but now, before the winter storms hit, is an excellent time to proactive assess the condition of your trees for potential limb and trunk breakage.
  • Mulch trees and shrubs. Apply two to three inches of mulch around all trees and ornamental shrubs. This helps to fertilize the plants and feed the soil, and also protects them against weed growth and loss of water when the warmer  weather returns, and helps to insulate the roots against cold weather in the winter.
  • Plant or transplant trees and shrubs. After the cold, seasonal rains have started is a good time to plant or transplant ornamental trees and shrubs. Cooler weather means less transplant shock to the plants, and over  the winter and spring, they will have time to begin to acclimate to their new environment before the stress of the next summer season occurs.
  • Prune your trees and shrubs. This is a good time to start pruning your deciduous trees and shrubs after the leaves have fallen and a tree’s branching structure is clearly visible making pruning easier. If you’re not sure what to do, or how to do it, call Good News Tree Service, Inc. for a consultation, pruning lessons or to have them to the pruning for you.
  • Prune coast/shore pines (Pinus contorta) and Scotch/Scots pines (Pinus sylvestris). These two pines are especially susceptible to the sequoia pitch moth whose larvae burrow into the tree trunks during the growing season (April through September) causing the trees to exude large amounts of unsightly pitch globules. While this seldom kills the tree, the bleeding of sap is not good for the overall health and vigor of the tree. It is advisable, therefore, not to prune these pine trees during the growing season, since the pruning cuts attract the moth, which then lays eggs on the tree, which hatch into tree-burrowing larvae. Pruning should be done on your pines from November to March.

Plant Health Care

  • Arborvitae Berckmann’s Blight (Platycladus orientalis). Spray with copper twice in the fall (late Sept. and early Oct., and again in early Nov. Spray again in early spring (Feb to Mar) if disease is severe. 
  • Fertilize trees and shrubs. Use with a low nitrogen granular fertilizer. The fall and winter rains will slowly dissolve the fertilizer into the soil and down into the roots. Roots continue to grow throughout the winter, so it’s good to feed them for the overall health and vigor of the plant. You can also have Good News Tree Service, Inc. deep root fertilize your trees and shrubs via injection of liquid fertilizers and soil conditioners directly into the root zone of the tree through hydraulic pressure. 
  • Deep Root Fertilization Trees and Shrubs. If the soil temperatures permit, hire Good News Tree Service, Inc. to fertilize your ornamental shrubs and trees (via hydraulic injection) to improve their root health during the winter season and to prepare them for the upcoming spring and summer growing season. When you do this, you will notice a marked improvement in the looks of trees and shrubs.
  • Magnolia Bacterial Blight. If your magnolia bush or tree has blighted leaves and flowers (dark, irregular spots) and the new shoots wilt and die in the spring, it may be magnolia bacteria blight. To treat, the magnolia needs to be sprayed once in the fall and twice in the spring near bud break.
  • Verticillium wilt. Treat maples and other trees against this potentially lethal soil borne fungal pathogen. The fall is the best time to treat your plants against this disease, and spring is the second  best time. Maples are especially plagued by this disease. During hot weather, symptoms include smaller than normal cupped leaves in the upper canopy, often with the death of the entire branch occurring. Maples are the hardest hit trees by this disease. Other trees susceptible to this persistent and potentially lethal fungal root disease include ash, box elder, golden rain tree, mountain ash, prunus spp. (cherry and plum), redbud, tree of heaven or silk tree, southern magnolia, tulip tree.
  • Willow Twig (Bacterial) Blight. Apply copper spray fungicide after the leaves drop.

Elsewhere in the Garden

  • Put slug bait around winter flowers.
  • Plant spring flowering bulbs.
  • Rake and dispose of ornamental tree leaves, or better yet, compost them and then spread the decomposed leaves back onto your shrub beds as a mulch next year.
  • Mulch your shrub beds. Put a two to three inches of mulch (e.g. bark dust, garden compost or wood chips) around perennials and other plants that might be sensitive to subfreezing weather.  Also, spread a fresh layer of mulch (e.g. bark dust, garden compost or wood chips) on all the bare dirt areas in your yard to prevent soil compaction from rains, to prevent weed growth and to enrich and help to condition your heavy clay soils. Adding a layer of mulch (several inches thick) over any tender perennial flowers, especially if the weather turns extremely cold and the ground freezes, will prevent the death of flowers such as dahlias.
  • Winterize your irrigation system. Provide winter protection to in-ground irrigation systems by draining them and insulating valve mechanisms.
  • Winterize your outdoor faucets. Protect outside faucets from subfreezing temperatures, and drain and store garden hoses in your garage or garden shed.
  • Cut English ivy off of the base of trees. (This can be done any time of the year.)
  • Feed the birds. Dutifully maintain your bird feeders. As winter comes, birds have a harder time finding food.  This includes both seed and suet feeders. During dry spells, keep your bird bath watering hold full of fresh water. Caring for the local wild birds brings life and excitement to your backyard by turning it into a bird-friendly sanctuary. The birds will thank you for your generosity by providing you with hours of entertainment, and by eating insect pests that harm your ornamental trees and shrubs. Remember to feed your local humming birds that overwinter in our region. If possible, fill your humming bird feeders with a syrup that contains only 100 percent sugar (e.g. sucrose or dextrose) minus any artificial sweeteners, red dyes and other chemicals. Your birds will be healthier for it. You can find excellent bird care products and advice from knowledgeable and caring professionals at your local Backyard Bird Shop.

Rose Care

  • Mid to late fall. Prune your roses down by about one-third and remove any dead flowers and dead or diseased canes. 
  • Anytime of the year. Heavily mulch your roses. Organic mulch (such as wood chips, rotted compost, rotted manure) is the best. While barkdust helps to hold moisture in the soil, it contains little or no nutrients, so it doesn’t feed the soil and thus won’t feed your roses.
  • For more information on the care of roses, go to the Portland Rose Society website at https://www.portlandrosesociety.org/all_about_roses.html.

Lawn Care

  • Fertilization. Late in the month, apply winter fertilizer which is vital to maintain healthy turf. 
  • Mowing. Continuing mowing as needed while the grass is still growing if conditions are not excessively wet and cold.

Meet Zulu the English golden retriever and service dog in training.

My wife, Sandi, (and I as her assistant) volunteer for a non-profit accredited organization that trains service dogs for PTSD and mobility issues. Zulu, an English Golden Retriever, is currently assigned to us.

The service dog training program for which we are volunteers is JLAD (Joys of Living Assistant Dogs) at https://www.joydogs.org) out of Salem, Oregon. JLAD is an ADI accredited program that is comprised of some 40 volunteers who take these dogs temporarily into their homes (at their own expense) to help train them.

Currently, JLAD also works with two prisons in Oregon where residents live with and do an amazing job training these wonderful dogs as an important part of their journey to become full service dogs.

When the dogs exit the program, they must pass a set of rigorous tests to be approved as a certified service dog. For those people who are recipients of these highly intelligent and beloved animals, it can make all the difference in their lives as these dogs are trained to respond to some 90 commands and to perform numerous tasks for disabled people.

If you are inspired to make an end-of-the-year donation to a worthy cause, consider JLAD as a recipient of your generosity. You can donate at https://www.joydogs.org/donate.

You can also contact JLAD through their website if you are interested in becoming a volunteer.

Thank you and may God bless you!

September in the Garden—A To Do List

This guide is tailored for the western valleys of Oregon and Washington. 

YOU can help to make the world a better, a more friendly, loving and beautiful place by being a good steward of the spot on this earth that you are privileged to be borrowing for a time—your garden. Nathan, the Treevangelist, urges you to treat your spot on this planet like your own personal Garden of Eden paradise. Then notice the joy that it will bring to you! This is your Divinely mandated responsibility. Your trees, shrubs, flowers and the wildlife in your yard will express their smiling appreciation back to you as they radiate love, joy and beauty bursting forth with vibrant and verdant life. The following garden checklist will help you to do just that.

Even though fall is knocking on the door with cooler nights, the daytime temps, though a little cooler, are still way up there, and our severe drought continues with no rain in sight. At the same time, as our forests burn up, the smell of smoke is often in the air. Ugh! What’s next? It has been a tough season here in the West, and a tough year for everyone, all things considered.

But despite it all, there is still joy to found in the garden. The flowers are still smiling joyfully as the hummingbirds show off their aerial acrobatics in their dive bombing raids of the flower’s sweet nectar. The trees are happily waving their leafy arms in the gentle breezes, the green grass is still growing, and, yes, the weeds are too. So extricate yourself from that black, depressing hole called watching or reading the news, take a break and get out in the garden for some rest and rejuvenation!

  • Fruit trees: This is an optimal time to prune trees that are done fruiting, since wounds will heal more quickly in warm weather. This is a good time to reduce the height of overgrown fruit trees, since they are likely to produce fewer water sprouts now then when pruned in the spring. 
  • Maples (including Japanese maples): Monitor the leaves of all maples and other trees and shrubs for symptoms of the potentially lethal verticillium wilt fungal disease. If you see branch dieback, call Good News Tree Service, Inc. Other trees susceptible to this persistent and potentially lethal fungal root disease include ash, box elder, golden rain tree, mountain ash, prunus spp. (cherry and plum), redbud, tree of heaven or silk tree, southern magnolia, tulip tree.
  • Mulch: Apply two to three inches of mulch around all trees and ornamental shrubs. This helps to fertilize the plants and feed the soil, and also protects them against weed growth and loss of water when the warmer weather returns.
  • Pines: Once the hot weather has passed, you can begin to prune your pines.
  • Pruning of trees and shrubs: You can do all aesthetic pruning of all ornamental shrubs and trees (except pines) at any time of the year including summer. Don’t over-prune the top crowns of thin barked trees (e.g. Japanese maples, flowering cherries), since the sun’s UV rays can cause trunk and branch bark dessication resulting in cracking and dieback of sapwood and even heartwood resulting in entry points for diseases and potential structural failure of branches and trunks.
  • Be careful not to do major pruning during periods of hot weather, since doing so exposes tender leaves underneath that haven’t acclimated to the sun’s ultraviolet rays yet, since they have been shielded by the layer of leaves you’ve just removed by pruning. Sun scald of these tender leaves may occur, especially on southern and  southwestern sides of the plant. Sun scalded leaves won’t kill the plant, but it looks unsightly and diminishes the plant’s ability to photosynthate (produce food for itself).
  • Pruning of large trees: Most trees in the temperate western valleys of Oregon and Washington can be pruned anytime of the year. If you’re not sure what to do, or how to do it, call Good News Tree Service, Inc. for a consultation, pruning lessons or to have us do the pruning for you. It is likely best to wait for cooler weather to prune stressed or sick looking trees. Call us if you have questions about this.
  • Prune fast growing ornamental shrubs (e.g. laurel, privet, photinia, laurustinus, barberry) that are beginning to look shabby. You may need to prune them again in the early summer for a more neat and manicured look. 
  • Tree and shrub removal and stump grinding can be done all year long. 
  • Trees: Have an ISA Certified Arborist with an ISA Tree Risk Assessment Qualification (like Good News Tree Service, Inc.) inspect your large trees for the potential of failure due to weak root systems and defects in trunks and branches. This can be done anytime of the year.
  • Conifer trees that are drought stressed: The Willamette Valley remains in a severe drought. Large native trees (e.g. Douglas-fir, western redcedar, spruce, native firs) are getting stressed and some are dying. If you have a tree that is showing signs of drought stress (e.g. pitch globules exuding from the bark, excess needle drop, yellowing of foliage), then you need to water your tree to save it, or pay the high price to have it removed after it has died. With a whirlybird, impulse or similar sprinkler or soaker hose, saturate the soil under the tree out to the tree’s drip zone (i.e. the outer tip of tree’s crown) for several hours once or twice a week to achieve deep root watering. Typical lawn irrigation systems don’t put out enough water to adequately irrigate the deeper roots of a tree, so don’t rely on your irrigation system to provide the water that large trees need to survive.
  • Watering: During the hot summer months, well-established trees and larger ornamental shrubs need little or no watering. However, newly planted trees and shrubs will need watering for the first two to three summers until their roots get established. Regular lawn irrigation isn’t sufficient to give trees and shrubs the deep watering they need to survive the summer heat. During warm weather, deep water your new plants at least once per week. During hot weather, twice per week.

Plant Health Care

  • Deep Root Fertilization: Deep root fertilize to promote healthy root development in preparation for next spring’s growing cycle.
  • Dogwood Anthracnose: If you missed the spring sprays topical fungal sprays, and you see signs of anthracnose on your tree’s leaves (reddish, purplish, brownish splotches), you can spray your trees with a basal bark fungicide. Call Good News Tree Service, Inc. for information on this treatment.
  • Verticillium Wilt: The fall is the best time to treat, and spring is the second best time. Maples are especially plagued by this disease. During hot weather, symptoms include smaller than normal cupped leaves in the upper canopy, often with the death of the entire branch occurring.

Elsewhere in the Garden

  • Put slug bait around your flowers and tender perennials like hostas. 
  • Apply two to three inches of mulch (e.g. bark dust, garden compost or wood chips) on all of your shrub beds. Covering bare dirt areas in your yard with mulch helps to prevent soil compaction from rains, and weed growth, and helps to enrich our heavy clay soils.
  • Cut English ivy off of the base of trees. (This can be done any time of the year.)
  • Feed the birds. Dutifully maintain your bird feeders. Bring life and excitement to your backyard by turning it into a bird sanctuary. The birds will thank you for your generosity by providing you with hours of entertainment, and by eating insect pests that harm your ornamental trees and shrubs. Birds in the yard are not only fun to watch, but they perform the vital task of eating harmful insects. Keep bird baths full. In hot and dry weather, birds need water to drink and to bathe in.
  • This is a good time of the year to plant trees and shrubs. Visit your local nursery and select your favorite ornamental shrubs and shade trees. After planting your new shrubs, just make sure that you water them well immediately and regularly subsequently for the first two or three summers until their roots get established. During warm weather (in the 60s to low 80s), deep root water once per week. During hot weather (mid-80s and higher) deep root water at least twice per week.
  • Fertilize your lawn. The cooler, wetter fall weather is also an excellent time to overseed your lawn to fill in the thin and bare areas.

Rose Care

  • Mid to late fall: Prune your roses down by about one-third and remove any dead flowers and dead or diseased canes. 
  • Anytime of the year: Heavily mulch your roses. Organic mulch (such as wood chips, rotted compost, rotted manure) is the best. While barkdust helps to hold moisture in the soil, it contains little or no nutrients, so it doesn’t feed the soil and thus won’t feed your roses.

Lawn Care

July Through September

  • Summer lawn maintenance. Summer is about mowing, watering, and pest control. Stay on top of mowing for a healthy lawn.
  • Irrigation. Water deeply, slowly and as infrequently as possible. Try to avoid watering established lawns more than two or three times per week if possible except during extremely hot conditions. It is not a bad idea to let the soil under your grass to dry out for a short time in between watering as this forces the grass roots to grow deeper in search of water thus making for a more drought tolerant lawn. It is best not to rely on timers for irrigation as temperatures will dictate water needs in addition to lack of rainfall. However, timers are helpful if you have lawns areas that are too large to micromanage or if you will be away for a period of time. 
  • Mowing. Mow once a week, removing no more than one-third of the height of the grass to avoid stressing it. Mow regularly to prevent weed seed spread.
  • Letting your lawn go dormant. If you want to save on your water bill during the summer months, you can skip watering your lawn if you don’t mind it turning brown. It is not dead; it is merely sleeping or in a dormant state. When the rains start up again in the fall, your lawn will turn green and start growing again.
