hi- I have a hydrangea bush, about 4' tall, that hasn't had any problems til now. Something is eating the very top leaves on a couple of branches. I don't see any pests when I inspect the bush. It's weird that something would climb up to the very top to munch a few leaves. Any ideas? thank you very much for your help!! ps I hope I have the right pics attached. I sent in another question about tree roots just now, with pics, and since I can't see the attached pics, I hope they are correct.
