Need help identifying problem with Red Twig Dogwood
Hello all, This past spring I planted two Red Twig Dogwood plants. One has thrived and at least doubled in size. The second did well for a while, but then stopped thriving and is only half the size of the first.
Right now they are both showing signs of the same problem - leaves have holes as though eaten, some leaves have brown edges and a few are completely dead and shriveled. I cannot see any obvious pests on the leaves.
I'm going to try to attach a couple of pictures - I've never done that before in these forums.
I'd really appreciate any help identifying what the problem may be, and what I should do about it. Thanks in advance!
