Instead, we're just shearing it off. You take the branches and tie them up. As they continue to grow, you tie them up. You don't do much cutting except after you get this wall of foliage and then cut off any vigorous growth that comes out. We'll prune two of the trees that way and selected shoots of the apple and pear will be directed out onto the wires.
Small trees are easier to manage and usually productive enough.
Full-sized trees are best where shade or high production is desired. Let us hear from you.
