Hollyhock Discoloration

Question

How do I prevent the leaves from losing pigment? Already they are blotchy and different shades of green. It happens every year. Is this a serious disease? Thanks.

Answer 1

It sounds like you may have powdery mildew. Hollyhocks are prone to this and it does make them look blotchy with varying shades of dusty green. This article will help:
