My Zephirine Drouhin climbing rose has leaves that are curling, turning brown, and being half eaten. I am attaching a picture. What can I do?
If you unfurl the leaves, you may find webbing, or leaf roller . It protects itself and feeds on the leaves. I think it may form a caterpillar. If I find them, I squish the leaves and remove them. I hope you don't get more infestation. The few I have found on my roses, have not proliferated much. But of course, I do not know about your zone.
