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.
Wait to make your first pruning cuts until two to three weeks before the average final-frost date, but before your roses begin to put on their seasonal growth. That's when you should prune your roses. Follow these pruning guidelines to help roses get off to a good start. For roses that bloom on new wood, like the vast majority do, major rose pruning should be done in early spring,when the bud eyes on the canes are just beginning to plump up and turn pink and swell, and after the last frost.
