|Lots of insect pests think hydrangea leaves are yummy. Beetles and caterpillars can make holes in the leaves. Check the undersides of the leaves to see what might be hiding and feeding on your plant. If you find caterpillars you can pick them off or apply Bt (bacillus thuringensis) which is sold as Dipel or Thuricide. It targets only caterpillars. If you find beetles, handpicking is usually enough to control them or you can use a neem oil based insecticide on your plant. Be sure to read and follow label directions. Best wishes with your hydrangea.
