Q: I am curious to know if you think my tree of heaven is diseased? I had a tree guy come out and he thought the tree was fine and healthy and this was natural. It is starting to show leaves but I just donít think it looks right. Any feedback would be appreciated.
A: The tissue that looks different is a canker which is like a big wart. Cankers like this are mostly cosmetic. Applying the Sick Tree Treatment is all I would recommend.
