Climbing roses are actually trained roses, as they don't climb on their own. Since most climbing roses are hybrids of bush roses there is no standard on time of bloom, whether the flowers are double or single, repeat or one-time bloomers. The trick to getting your climbing rose to bloom more profusely is to train the canes in a horizontal direction. To keep them from overgrowing the support system and to keep them blooming, climbing roses should be pruned once a year while they are dormant, either in the winter or early spring.
Place your pruning shears in a tub and cover them with a solution containing 1/2 cup of Lysol disinfectant and 2 1/2 cups of water. Allow them to soak for three minutes, then rinse them under tap water.
Remove foliage from the climbing roses.
Cut away any diseased or thin twigs. Cut the twig back to the cane from which it was growing.
Remove any canes or shoots that are crossing over others.
Remove the fasteners from the main canes and cut them back so that they better fit the support system (wall, trellis, etc).
Prune all lateral shoots. These are the branches that grow out of the canes. Lateral shoots should be cut so that only two to five buds remain. Make the cuts 1/4 inch above a bud.
Reattach the main cane to the support system.
Step back and evaluate your work. If some stragglers remain, cut them back so that they better fit the support structure.
