I have what I am assuming is a crab apple tree in my side yard. It's in a pretty sad state but I'm not sure what to do to fix it. I am in zone 7a and we are about to enter fall so I'm not sure how much (if any) pruning I should be doing. My biggest confusion is that it doesn't seem to have a trunk. It looks like it's just a bunch of branches coming out of the ground. Any advice on what to do to prune this tree and when to do it? If it helps at all it has dark pink flowers in the spring.
