I have a commercial orchard and am pushing out a lot of apple trees that have large graft unions. This is where the variety meets the rootstock and forms a big bulb that looks from the outside like a burl; about 14-24" in diameter. Doesn't sound like much, but apple trees in orchards today don't get very big as no one plants trees that get large. Do you think these parts of the tree are good for turning, and where could I sell enough to justify having Santa bring me a new Laguna bandsaw ?
