Prune your Knock Out Rose to about 18" above the ground. This ensures that the plant will have a good habit and healthy blooms throughout the season. Knock Out Roses can be pruned lightly throughout the season between flushes of buds and blooms to encourage heavier repeat blooming. Discontinue pruning about 2 months before typical first frost date.
