A few members have b118 on poor sandy soil and do well. CrazyEd is one of those guys. I feel B118 treated richly causes problems. Well fertilized, quality soil, well watered. I also feel b118 needs to be pruned hard too. Russian B118 was made for poor sandy soils and colder climates.
Have 2 or 3 M7's. Almost feel i should of been doing m7's all along, especially ib my single row north-south 16ft spacing.
Little surprised granny smith isnt discussed on here much. Good warm zone tree and easy to find.
Been very happy with turkey creek, Saint Lawrence nusery, and mehrabyan nursery. whitetail crabs is ok too. Twist his arm a bit and he will yell you what rootstock he had on what. Fall delivery is s very nice plus from him, if you dont mind planting during hunting season.
