Consulting Rosarian Tip of the Month



Prime bare root planting and transplanting of existing roses continues up to the middle of the month. Mound soil up around newly planted rose bushes or cover entire bush with burlap or evergreen boughs to prevent dehydration. After two weeks, wash soil away gently a little at a time to permit new growth to become acclimated.


In late April pruning of winter hardy shrubs may begin. Prune canes back to green stems and an outward facing bud eye. Seal canes with cane sealer after pruning. Elmer’s glue or colored finger nail polish to prevent cane borer damage. Plan to keep winter protection on less hardy bushes until mid-May. Keep beds clean. Deep water as needed.  Check out Dave Ingram’s April “Getting Started with Roses” Volume III for additional timely tips.


  • Continue to deep water roses to a depth of 8-12 inches when necessary (no measurable moisture in weeks) – but avoid over watering.
  • Stock up on Mile-Hi Rose Feed fertilizer. Be ready for the growing season.
  • If starting a new rose bed, and you did not prepare the area the previous fall, amend soil as soon as the ground is workable. Consider raised beds if drainage is a problem. Roses need sun for at least half a day and can use full sun. Morning sun with afternoon shade is preferable. Do not plant roses near large trees or hedges. Remember to update rose bed maps with names of newly planted bushes. Consider using garden labels.
