Hello. My name is Dave and I'm new here. I recently bought a home in St. Louis and have an Oak that looks to have a problem. Please have a look at the pictures. I'm not even sure what kind of oak it is but the bark is falling off. I can tell you that the tree had a lot of ivy crawling on it which we pulled off. Some of the damage looks older but bark is continuing to peel off the tree. How do I save this tree or can I? Might I have a fungus or a bug issue?
