Rhododendron
The problem you have described is either chemical damage or
rhododendron gall midge. Chemical damage should be associated
with a chemical application and should affect more than one
species. The rhododendron gall midge is a tiny insect feeds in
the spring and causes distorted leaves to emerge. There is no
way to undo the damage once it has occurred. Chemical controls
for the rhododendron gall midge are not listed in the Chemical
Manual.
