Hollyhock

Question

I planted some hollyhocks last year but they turned yellow after they got about a foot high and I thought they all died. This year one came back, but it’s starting to do the same thing. Help!!!

Answer 1

Hollyhocks are prone to powdery mildew and other fungus. Treat them with a fungicide. This should help prevent the yellowing on the leaves.

As a precaution, I would also check watering for the plants. If they are not getting enough water, this can also cause yellowing.
