All you really need to do is cut back diseased and dead branches to a healthy point. That can be done at any time. You can also cut back any canes that grow out of control at any time during the season. If you are trying to train or shape your climber, prune it after it has bloomed in late spring. To train climbers to grow wider, cut back your canes just above an outside-facing bud.
Suckers are weaker canes that grow up from the base of the rose plant.
All suckers should be pruned off, no matter what type plant you have. Clear nail polish or white glue can be applied to the raw end of any pruning cut to deter pests. All rights reserved.
