Help! Holes in Rhody Leaves
I think there's at least one other posting here about a similar problem, but I couldn't view the photo(I also didn't like the answers!), so I'm going to post pics of mine. I'm in SE Michigan.
This large group of holes appeared very suddenly, although I think I had noticed a few isolated holes previously. Note that there is one leaf in the lower center of the pic that is definitely chewed - I see that once in a while, don't know whether it's related to the holes or not.
All the holes are in new growth leaves, I don't see any holes in older leaves. I recently put pine mulch(from my own trees) around this plant, and I have sprayed it a few times this summer with a generic Ortho Fungus & Insect killer. Please help!
