It is never too late (or too early) to prune knockout roses! Pruning encourages new growth so trimming everything back a bit in the spring will result in lots of new stems and branches, and more flowers. Now is a perfect time to prune! You can remove up to two thirds of the plant and it won't mind a bit.
