When do knockout roses need to replaced! #333785
Asked June 18, 2016, 3:34 PM EDT
We purchased a home with a knock our rose garden which was planted about 14 years ago. The man who helps with the gardening told us the plants should be replaced every 5 years. The plants are healthy but some are very woody and misshaped. Is the "gardener" correct?

Expert Response
As long as they are healthy, they do not need to be replaced. They may need to be cut back hard every once in a while to bring back a good shape but not replaced. Pruning like this should only be done in the spring (March).
