Is there a problem with this tree?
Hello, our next door neighbor has a large tree with branches growing on our side of the fence. We moved here a year ago and I don't recall if the leaves were the same last year. They look strange and bubbled. Is this normal or do you think something is wrong with it. If so, what suggestions can I give my neighbor to help the tree. I'd also like to know if it is diseased, could it affect the trees and plants in my yard? What about the leaves that fall on my side in autumn, should I compost them or throw them away? Thank you for your help.
