Rhododendron issues: holes in leaves and browning
I did some research on the forum, but couldn't find anyone else that described this specific problem.
We have several very large, mature, beautiful Rhododendrons. Yesterday, I noticed that on 2 of them, something has been eating the leaves in several parts of the plant. There are also some brown, dry parts to some of the leaves. Here is a link to a few images: Rhododendron
We bought the house last year, so I don't know the variety or if this is a re-occurring issue. They look healthy otherwise (they are magnificent!) But I do want to make sure I take any necessary precautions should this be a big problem and spread to the other plants.
Thanks for any advice! I love this website.
