Those Jonathans look beautiful, Al. That's some work bagging 900(?!?!) apples. We picked up some Jonathans from an orchard recently, and they were very tart, but still very good. They probably should've sat for a week before we ate them to maybe let them sweeten up, but they were hard to resist. Are yours like that?
Those yellow apples look kinda like Grimes Golden, but they are related so I guess there will be some similarities. Did these trees put out any fruit last year, and were they smaller then compared to this year after you had pruned them? What a treat to have two nice old apple trees already there when you moved in.
