All-Winter-Hangover is a tree that St. Lawrence Nursery sells - I think it's a proprietary variety (?). It gets apples about 1 1/2" in dia. that are delicious to eat if you want to rob some from the deer. Ours have good branch angles ( on their own ) and by year 3 have put on up to 50 apples. Last fall the apples dropped periodically into late December, but the tree was only about 12 ft. tall - 3rd leaf. I think as the tree grows more and has bigger fruit loads, they'll hang on longer. ( we have 3 more now ) They don't seem to be disease-prone, and they haven't been a bug magnet either. I can't vouch for CAR resistance because we have no cedars / junipers around for miles, so we don't have that problem. So far, they've been NO PROBLEM AT ALL. The oldest one is probably our best looking apple or crab on the camp's ground. This year's crop is between 40 and 50 apples again, and we had some late frosts this spring. They turn red when ripe.
If I had another old field that I could plant to apples & crabs, I'd have at least 10 All-Winter-Hangovers in there. October thru December drops for us here. I love 'em.
