My roses have chafers. The leaves are all affected from the bottom to the top of the plants. Do I need to cut the plants down? If I only trim the leaves affected the plant will be bare except for the blooms, which have not been affected. Thank you for your help.
No need to cut them all the way down. You can spray with THIS to kill the beetles. Trim off the worst of the damaged leaves and feed it with a good rose food like Espoma Rose-Tone according to the directions. As new growth occurs, you can gradually remove the rest of the damaged foliage. They will bounce back quickly from this.
