Interesting little volume. It’s not a comprehensive book on pruning like the one I just finished by Gilman. It mainly focuses on how and why to make your pruning cut right above the branch collar. Lots of great photos of trees, wounds, proper cuts, lots of cross sections through a trunk/branch to show you what’s going on inside. Not a lot of text, just an ardent and thorough plea to please make proper cuts right above the branch collar! There is some assorted text at the end, some excerpts from other tree experts the author admires. It’s a great companion to a more thorough pruning text like Gilman.
