Knock Out Roses Pruning Steps: To maintain a size of 3–4’ w x 3–4’ h, Knock Out Roses should be cut back once a year to 12” high. Check your rose bush from time to time in late winter/early spring, and when you start to see new shoots growing from the canes on your rose bush, that’s a good sign that it’s time to prune.
Jun 11, If no rose bush forming pruning is done to adjust their height and/or width, the Knock Out roses can reach 3 to 4 feet (1 m.) wide and 3 to 4 feet (1 m.) tall.
In some areas, an early spring pruning 12 to 18 inches ( cm.) above the ground works well, while in areas with harder winters they may be pruned down to around 3 inches (8 cm.) above the ground to remove the dieback of the canes.
