What is eating the new leaves on my grafted gums?

Dear Lee,

If the leaves have been chewed it is likely that a caterpillar is doing the damage. You can apply a product called Success Naturalyte Insect Control. This product will control a wide range of caterpillars and helps control insects that have become resistant to traditional chemicals. When spraying, make sure you apply the product to both the top and the underside of the leaf.
