What is eating leaves of tree
I think I have a Japanese Maple tree. This tree gets watered every other day by a system in the early morning. I use typical pellet weed n feed on the surrounding lawn. I also use pellet lawn pesticides yearly. I have a neighbor with the exact same tree and she does not have any issues like this. Her tree is lush and full of healthy looking leaves.
This year the tree leaves started looking very bad. I think something may be eating through my leaves and causing the terrible damage - however I have never seen bugs on the tree. But, there are little cocoons hanging all over the tree that lead me to the bug suspicion. I could be wrong.
I have included a picture so you can see the damage done to the tree leaves, as well as red circles around some of these cocoons.
Does anyone know what is causing the damage and how I can alleviate it?
