BottomLand, I think I can help. I've got four producing crabapples than I'm grafting onto, and I'll certainly cut you a batch of scions when I prune next month. I've also got access to native persimmons that I'm going to be cutting about the same time.
As for what I need, I have two deer pear trees onto which I'd like to graft eating pears. I already have enough Bartlett scions available, but most anything else will work. The most fire blight resistant variety would be preferred. Along with that, I would love to have southern apple varieties to graft onto my crabs. I also have plenty of plain old Honeycrisp to spare.
