Prune the roses after the buds break dormancy. The major pruning period for knockout roses is in late winter to early spring, just as the bush begins to break out of its dormancy stage. 1  Check for bud formation on the stems of the plant. 2  You can still prune the plant even if new growth is starting to develop, though.
I did have a question from a gardener about her Knock-out roses. She wanted to know if she should cut them back now even though they were still blooming. You know this the wonderful thing about this very special rose. You do not need to do anything to it until next spring. If there is any winter damage to it, come spring you can cut it clear back without doing any damage to it. They have really been blooming big time this year.
