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.
Timing for Shrub Rose pruning - Zone 5. I can't recall if the best time to cut back your shrub roses was a few weeks before bud swell or closer to bud swell. I fought the urge to cut back extremely vigorous fall shoots so at this point I'd rather wait until its the right time. Thank you for reporting this comment.
