Pruning out dead, damaged or diseased wood is done to roses all through the year. Prune out canes that are black to dark brown with no green showing. Cut off shriveled canes any time of the year as well. Cut dead wood to the ground and remove ruined wood below the damage, if some of the cane is salvageable. Wind or snow damage may only affect the top part of the cane, so cut right below a node in the stem to include the damaged area. Destroy the clippings rather than put them in a compost pile.
Remove flowers after they fade and die to keep rose bushes tidy. It also encourages re-blooming red rose varieties, like Showbiz, Love and Mr. Lincoln, to continue to bloom. Roses that only bloom once a year, such as old red gallica or damask varieties, Charles de Mills, and Rose de Rescht, do not need deadheading for any other reason than to keep them tidy. Deadheading will not produce more blooms as it does with continual bloomers. Stop deadheading all roses after October 1st, so the plants prepare themselves for winter.
Prune old varieties of red climbing roses and ramblers after they bloom, as they only bloom once during the season. There are several varieties of red climbing roses that are everblooming including Red Blaze and Red Stairway to Heaven, which should not be pruned after blooming in order to continue flowering. Those red roses that respond well to after-bloom pruning are Chevy Chase, Excelsia, William Shakespeare, Sophy's Rose and Be Bop. Old climbers and ramblers should be pruned to keep shape and avoid becoming a bramble. Cut out one or two old canes, and cut back stems smaller than the diameter of a pencil that cross or tangle with each other.
Most roses require pruning in spring around the same time the forsythia blooms, or before the leaves begin to grow on the rose bush. Hybrid teas, grandifloras and floribunda roses including Chrysler Imperial, Oklahoma, Champlain, Ronald Regan, Wing Ding and La Sevilla require strong spring pruning. They all bloom on new growth, so encouraging stems to grow enhances flower production. Remove old canes keeping about three to five of the healthiest, making sure they are well spaced around the plant. Cut stems smaller than the diameter of a pencil and cut those stems that cross one another. Cut back all canes 12 to 24 inches depending on the size of the plant.
