Kyrt, I have apple, plum, and apricot trees, the bottom of the canopy is at about 5-7 feet, just high enough to walk under. I guess I could plant AO and keep it short? Yes our rainfall is less than 18in a year, but we irrigate once a week during the growing season. I don't mind having to prune it, I just don't want to plant something that is going to destroy my orchard.
