Central Sierra: From Now Til March, It's Time to Prune Your Roses
An Invitation to Garden Beauty: A Rose Pruning Primer
It’s that pruning time of year! The period from Christmas until early March (depending on elevation) is the best time to get started. Your bushes will look more attractive and produce larger flowers with good pruning, and you can shape them to the proper size for your garden. The removal of dead and diseased canes also improves rose bush health by stimulating the production of new growth with the emergence of vigorous new canes from its base. Even if your bushes still have leaves and flowers, their removal now is a chance to wipe away last year’s problems and set a new path for the coming season.
The best tools required for rose pruning
Use sharp bypass hand pruners for most cuts, and long-handled bypass loppers for thicker canes and hard-to-reach places. A fine-toothed curved saw will remove the thickest canes. A pair of leather gloves reaching to the elbows protects from thorn pricks.
The parts of the rose that should be pruned away
Completely remove all dead canes (grayish or brown in color and shriveled looking) and canes that have been less productive with a clean cut close to where they emerge from the crown at the base of the bush. Completely remove diseased and damaged canes or cut them back to healthy wood at least one inch below the affected area so the inner wood (pith) is white. Remove all suckers coming from the root stock beneath the bush. Select the strongest three to six outer canes (smooth and green or bronze in color) to become the foundation for next year’s growth. They will ideally be arranged in a vase-like shape around the open center of the bush when pruning is finished.
Remove with a clean cut at the parent stem any growth that is smaller than a pencil and which crosses or rubs other growth. Direct new growth away from the center by making cuts at a 45-degree angle, one-quarter inch above a bud that faces upward and to the outside of the bush. Buds can be found at leaf attachments; some will look like red dots or green smiles, while others might already be pushing leaf growth out. Remove all growth headed toward the plant’s center to discourage fungal diseases by improving sunlight access and air flow. Shorten the remaining canes on established hybrid tea, floribunda, and grandiflora varieties by one-third to one-half in length. Shrub and English roses should be given a lighter pruning, with 6-8 healthy canes left on the bush.
Post-pruning tasks for healthy, beautiful roses
After pruning, remove and dispose of all remaining leaves, along with pruned cuttings, fallen leaves, and debris collected from under the bush – no composting. Make a heavy application of dormant spray or horticultural oil on a day where there is no wind and there will be no wet weather for at least 24 hours. Thoroughly spray the bush and the ground beneath it to suffocate any remaining insect eggs or fungal spores. Apply a layer of mulch 2-3 inches deep, pulled away from the base of the plant. Fertilize about four weeks after pruning; water deeply after application.
Enjoy a wonderful rose year!
