Hello! I was wondering if anyone might help me figure out what kind of apple tree this is. It was planted by the builder a couple years ago. It produced fruit of approx. the same size last year. Fruit is very tart. I think it is a type of crab apple, but not sure. Thanks!!
Seems pretty healthy to me. Keep up the maintenance. If it is a Dolgo you can graft it over to something else...ask someone who is experienced in that area.
