Knock Out Roses – To Prune or Not to Prune

David Yost, Merrifield Plant Specialist

At the Plant Clinic, a lot of gardeners have been asking us if they should prune their Knock Out Rose bushes.

We tell them that it depends on what size they want them to be. Knock Out Rose bushes can grow to about 8’ tall and 8’ wide. If you want them that large, don’t trim them.

But if you want your Knock Out Rose bushes shorter and bushier, now is a good time to cut them back to a height of about 12 to 24 inches. Also remove dead branches and spindly growth and thin out crossing and rubbing stems.

After pruning, apply Bayer Advanced 2-in-1 Systemic Rose and Flower Care every six to eight weeks to keep your rose bushes growing, blooming and free of insects.
