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.
The Knock Out series of roses is a group of hybrid shrub roses introduced by the Conard-Pyle rose company, beginning in 2000 with the original red-flowered variety, Knock Out. The series has now expanded to seven rose varieties. The majority of Knock Out roses are sold in containers, ready to plant. They can be installed in the garden any time after the last spring frost, but special precautions should be taken if you are planting during the hottest part of summer when climate conditions put added stress on the plant.
