In this guide I discuss pruning for the desires of man, but also for the health of the trees and their associates. I have tried to make this guide easy to read, easy to understand, and easy to put into practice. I hope you find it that way. I emphasize that this is a guide and not a rule book full of absolutes. Themes are presented . There will always be variations on the themes. And finally, please use great care and caution when pruning. Because information is given does not mean that laymen should attempt all pruning operations.
