The Q&A Archives: Hollyhock Pest?

Question: What insect eats my Hollyhock leaves every year to the point that they look like lace? I never see the culprits on the plants!

Answer: Skeletonized leaves are usually the work of young catapillars, before they grow large enough to eat the entire leaf. Look under the leaves for them. You may see a flattened, slug-like creature feeding there. Some insects are most active at night, so if you can't find them in the daytime, do a Sherlock Holmes investigation with a flashlight at nite! If you find catapillars, sprays with B.t. as the ingredient are a safe, organic control option. These are available under many brand names. Good luck with the investigation!
