Pruning Roses


pruning1WHY PRUNE?

  • To encourage the growth of new flowering wood, this results in the production of more robust flowers.
  • To remove dead, dying, diseased, injured, and broken wood.
  • To remove crossing canes or canes too close to one another.
  • To promote air circulation through the plant in order to decrease the proliferation of disease and insect infestations.
  • To promote light penetration to the crown or bud graft in order to encourage healthy growth.
  • To remove suckers emerging from the rootstock.
  • To remove old canes which become less productive and to stimulate new basal breaks.
  • To improve the shape and appearance of plants.

pruning2HOW TO PRUNE?

  • Remove all obviously dead wood.
  • Remove wood that is heavily scaled, sun scalded or covered with lesions.
  • Remove any canes that cross, touch or grow into the center of the plant.
  • Examine wood that formed over the summer. Cut canes back one-half to two-thirds to wood at least one-half inch in diameter.
  • Make all cuts at a 45° angle above a live, outside-facing bud eye. Use sharp bypass pruners to ensure a clean cut that doesn't crush or tear the wood.
  • Remove any remaining leaves.
  • Seal cuts more than one-quarter inch in diameter to prevent any boring insects form entering canes.
  • Spray dormant roses with copper and horticultural oil. Copper helps to decrease the incidence of fungal problems during the growing season, and oil kills insects in their various overwintering forms.
  • Clean up. Remove all rose leaves and other debris from around the plants. Do not compost!
