I have an heirloom apple tree in my background that probably dates from when the house was built, over 100 years ago. Once the tree was freed from the blackberries choking it we got a lovely crop, tart and tasty. But I haven't been able to identify it yet and am hoping the Forum can help. Additionally, the tree this year seems affected by some disease and I'm hoping to be able to treat it. Crop this year was much smaller, but I know sometimes apple harvests are biannual. Any help on either issue much appreciated.
