What insects eat hollyhocks?

Hollyhocks are susceptible to a variety of insects, with the most common pests being aphids, spider mites, and Japanese beetles. Aphids feed on the sap, weakening the plants and potentially causing leaf curl, while spider mites can cause stippling and yellowing of the leaves. Japanese beetles eat the foliage and flowers, leading to significant damage. Regular monitoring and appropriate pest management can help protect hollyhocks from these threats.
