Today is Saturday August 9th. Today, while we were away, my neighbor decided to prune my beautiful black oak tree. I don't know why, because it is (or was)beautifully balanced. I read in an article that this is not the correct time to prune a tree, and also about the chances of causing oak wilt. The article was from a Texas University and I want to know if the same rule applies to trees in Mid-Illinois. I do not see where they had treated the branch wound. You help would be appreciated.
