You could ask your library to purchase them if they do not have them.

Remember, we need to treat the system and not just the wound. MODERN
ARBORICULTURE will help you understand treatments of systems. MODERN
ARBORICULTURE is a systematic approach to the care of trees.

of the list for pruning. I have read many other books on pruning and few to
none actually explain how branches form on trees thus helping to understand
how to remove a branch correctly.
