Ok, I have a grasp on the root pruning, doing NOT what the books say. Most books I read say to "trim off an inch or so around the outside of the rootball", which I figure are the productive roots. I trim the old roots, that are more or less just anchoring roots. Anywho, I also have read that when you prune roots, you should also prune the top growth as well, at about the same ratio that you prune the roots. Is this true, or can I just root prune, and we're good to go? Thanks.
