Rose Care Month-By-Month

Join the Treevangelist in helping to make the world a more beautiful, kinder and loving place one tree and one flower at time: Plant lots of flowers everywhere all of the time. The following guide will help you to be able to plant and care for the glorious rose flower.

While you’re at it, also practice the golden rule and let your light shine and your river of life flow by telling those around you about the love, joy and peace of Yeshua the Messiah (Jesus Christ).

Consider the lilies, how they grow: they neither toil nor spin; and yet I say to you, even Solomon in all his glory was not arrayed like one of these. (The Bible, Luke 12:27, Yeshua the Messiah/Jesus Christ speaking)

Therefore whatever you want men to do to ou, do also to them. (The Golden Rule from the Bible, Matthew 7:12, Yeshua the Messiah/Jesus Christ speaking)

  • Mid to late-February  or early March (or after the threat of hard frosts have passed: 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.
  • April: 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.
  • 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! 
  • Late spring, summer and into early fall: During prolonged warm, dry weather, deep root water your roses at least once a week. A rose needs five gallons of water per plant per week.
  • As needed, remove spent flowers after they are done blooming.
  • End of June: Fertilize roses again.
  • During hot summer weather: Spray roses with water (not in the morning, though) to cool them down, and spray top and undersides of leaves to wash off pests such as spider mites and aphids.
  • Late August: Fertilize roses again.
  • 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.
