We have a guy near here that does grafting of apple trees. He has classes on it and sells all the supplies. They have an orchard, but I think grafting is his main focus. You can buy apple trees from him, but I don't recognize any of the apple types. He has plums also. According to his website, he will do custom grafting to order also. I am thinking of seeing if he will make me a plum tree with a couple of varieties of plums. We don't eat a lot of plums, but I would like to grow some for making plum sauce. However, I don't want to loose too much space in the orchard to plums. I want apples, cherries, pears, raspberries, blackberries, blueberries and peaches. Peaches are going to be iffy, not sure we are in the right zone, we are close and get lake effect, but it will be iffy. A friend of ours has a couple of peach trees, but we are north of him.
