The Q&A Archives: Knockout Roses Pruning

Question: When is a good time to prune Knockout Rose?
Also how hard can you prune them back?

Answer: Jason,

Anytime from now through February is fine. You can cut them back as much or a little as you like. I generally shear mine back by about 1/3 in winter and then do a lighter shearing in late summer to promote regrowth and a big fall blooming show.

Thanks for the question. Please stop in again soon!
