Hollyhock Pests

Question

The leaves of my hollyhocks (single, ‘perennial’) are made lacy (and eventually turned brown) by something that eats them. The recommended treatment for hollyhock weevils is Orthane, but it is not sold in New York. Are there other treatments, or might there be another cause of the lacy leaves?

Answer 1

Best control is regular inspection of plants. Remove and destroy seed pods before larvae emerge. Adults can be shaken from the plant. Occasionally, insecticidal soaps can help relieve problems as well.
