|Knockout roses are usually pruned in the spring and then again in the late summer. You can prune them in the winter if necessary. Just wait until after the first frost in your region so the plants are dormant. If you prune them before they go into dormancy they will grow and the new growth will be frost tender. The new growth can die back in the winter and you'll need to prune again. So, wait until late winter or early spring to prune. Enjoy your garden!
