Rolled leaves on hydranga plants
Hi Mary Anne,
Thanks for writing. It sounds as your hydrangeas have a leaf roller infestation. Unfortunately, once it rolls the leaves, it's tough to deal with. If you're seeing just a few affected leaves you can pick them off and throw them in the trash.
Happily, it's easier to prevent this from happening again. Next year spray your hydrangeas with a product such as Bt (a bacterium that only affects caterpillars), neem oil, or a similar product to get the pests when they're young.
