March in the Garden—A To Do List

YOU can help to make the world a better, a more friendly, loving and beautiful place by tending your spot on this earth that has been given to you—your garden. Here is a to do list to help you to do just that. 

Then the LORD God (Yehovah Elohim) took the man and put him in the Garden of Eden to tend and keep it. (Genesis 2:15)

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

Tree and Shrub Care

  • Fruit tree pruning. Prune your fruit trees for fruit production. You can also prune grapes, can and trailing berries once the threat of major frost is past.
  • Plant fruit trees.
  • 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/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.
  • 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

  • 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 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): This leaf blight affects ornamental and flowering cherry, plum and prune trees. Apply fungicide in late fall, and in the spring prior to bud break and after the flower petals fall.
  • Deep Root Fertilization: Deep root fertilize your trees and shrubs as soil temperatures warm up.
  • 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

  • Put slug bait around winter flowers. Though the weather may be cold, slugs are still active.
  • 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.  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. Remember to feed the humming birds, who have few flowers to feed on during the winter. Birds in the yard are not only fun to watch, but they perform the vital task of eating harmful insects.

Street Tree Recommendations for the Western Valleys of the Pacific Northwest

Why This Is Important and  How It Affects YOU

The following list of recommended columnar or semi-columnar street trees for the western valleys of the Pacific Northwest is the convergence of several efforts on the author’s part.

This list is the distillation—the crème de la crème—of the analysis of numerous varieties of street trees from various lists compiled by numerous people, organizations and local municipalities. The best choices, in the author’s opinion, have been carefully selected. (More suitable street trees are being added to the list as they come to the author’s attention. So what makes the author’s opinion worth anything? Glad you asked.

Nathan Lawrence, ISA Certified Arborist and a second-generation Pacific Northwest arborist and horticulturist who has been earning a living caring for trees in Northwest Oregon since 1972, has put this list together based on long experience dealing with countless varieties of trees and learning how they react in numerous situations including wind, rain, ice, snow, blights, drought, attacks from pests, construction trauma, lightening, poor growth habits, structural failures, human neglect and more.

While owning and operating a tree care company in Northwest Oregon since 1985, we have Continue reading

Trees Benefit Everyone and Everything More Than You Know

Trees are a vital part of every day human quality of life

  • They provide us with shade.
  • They cool our homes.
  • They provide us many products we use daily: Paper, wood, chemicals, oils, resins.
  • Trees promote feelings of well-being and peace among people.
  • The foliage of trees help to mark the changing seasons, thus helping human to mark time.
  • Trees are a place for children to play in, under and around.
  • Because trees can survive for hundreds of years, they serve as property boundary markers, memorials of important historical events. Trees thus help bring people together, to unite people and to help people stay connected to their historical roots.
  • Trees act as gathering places for social activities and events. They can act  as places of unifying people, families, communities and generations.
  • Trees provide visual barriers, create screens, promote privacy, and make separations between divergent and sometimes conflicting elements of society.
  • Trees serve as wind screens and to buffer the impact of storms.
  • Trees increase property value.
  • Trees provide wood for fuel.
  • Trees improve the livability of cities for countless reasons. Trees add visual, emotional and psychological appeal, since few things can compare with the aesthetic impact and seasonal interest that trees offer the urban setting. They provide huge visual appeal to any area and can significantly enhance the design of a streetscape. Trees adds aesthetic beauty to one’s living space and improves the quality of life.

Trees are an essential economic asset for people and they create economic opportunities Continue reading

Are your trees hazardous? Are you sure? Here’s how to find out…

Are your trees safe, or are they dangerous, hazardous and at risk of breaking or falling down during the storms, wind, snow and ice that will inevitably pummel the Wilsonville region this winter? 

Trees are a major part of our lives. We love trees! They’re nearly everywhere including where we live, walk, play, drive, work, eat, recreate and go to school. Sometimes we even plan activities around them. We take them for granted because they are big, old and seem so permanent, stable and immovable. Most of the times, trees cause us no problems. However, trees can, at times, become dangerous. If they fall over or break apart, they can cause serious injury or death to humans and animals, and major damage to property.

How do you know if your trees are at risk of blowing over or breaking when the storms come? What are some signs that your trees might be dangerous and hazardous and might become victims to the ravages of winter storms including ice, snow, wind and rain?

Here are some signs that your tree might be a hazard tree: Continue reading

How to “Storm Proof” Your Trees and Shrubs

Are your trees ready for our fall and winter storms? Winds, ice, snow and even rain can cause damaging (and expensive) tree failures. The twisting and torquing force of wind on trees combined with soils super-saturated from rain can cause trees to break or uproot. Ice and snow are heavy, which can put stress on trees, causing them to break apart.

What can you do to prevent the uncontrollable forces of nature from indiscriminately, and without your permission, “pruning” your trees often resulting in damage to property and injury to people not to mention loss of property value due to broken, decimated and just plain ugly trees? If you are in Wilsonville, Oregon or the nearby cities including Tualatin, Canby, Aurora, Hubbard, Sherwood and the surrounding areas, we can help!

Be proactive and have an expert ISA Certified Arborist examine your trees before the winter storms hit the Wilsonville region causing damage to your trees.

Even better, the check up on the health and stability of your trees is absolutely free—without any cost or obligation to you. All you have to do is to call Nathan Lawrence at the Good News Tree Service, Inc. in Wilsonville at (503) 682-9466 to schedule a free consultation and Continue reading

The Hymn of a Ponderosa Pine

 

 The inspiration of this poem and its birth occurred, while meditating next to the  Deschutes River in La Pine, Oregon, during Sukkot (the biblical Feast of Tabernacles) in 2018, while gazing admiringly at the mighty, towering ponderosa pine trees (Pinus ponderosa) that stand as sentinels gracing its banks. At the same time, the words of the biblical First Psalm were floating around in the author’s mind.

By Nathan Lawrence

La Pinus1 ponderosa2 at De Falls3 River waters4;

A weighty5 giant pondering6 heavenly matters.

Rejecting your former blackjack7 past,

Basking now in heaven’s light at last.

Arms and trunks are tanned a bright orange hue8,

With muscular limbs upraised in praise to You9

To the Messiah, the radiant Sun of Righteousness10!

Part 2 Continue reading
