Consulting Rosarian Tip of the Month



Continue planting bare-root roses 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 – with acclimation to warmer days. Late in the month, pruning of winter hardy shrubs may begin. Prune canes back to green stems and an outward facing bud eye. When pruning seal canes with cane sealer like Elmer’s glue or colored finger nail polish to prevent cane borer damage or if borers have been a problem in the past. Plan to keep winter protection on less hardy bushes until mid-May. Deep water as needed when spring moisture is sparse.


April is a good month to clean up the rose beds, remove old leaves, trash and other debris. Take an inventory of supplies and tools. Purchase new pruners, you are worth the price of good ones. Stock up on fertilizer and any supplies you might require for pest management. Get ready for the growing season!


If starting a new rose bed, and you did not prepare the area the previous fall, amend the soil as soon as the ground is workable. Study rose literature and continue landscape planning. 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 having garden labels made for them. Growing Roses in Colorado (GRIC) has a wealth of information on selection and care of roses.
