I have found this book to be a very helpful reference on pruning fruit trees. I have not found anything more comprehensive and easy to understand on pruning. The part of the book on insects and diseases is also helpful, but not comprehensive. What I find less useful is the list of suggested varieties. I find that many of the recommended varieties are hard to find in the US and highly biased to the taste of the writer or perhaps the British public. For selecting fruit tree varieties, The Fruit, Berry and Nut Inventory, edited by Kent Whealy and copyrighted by the Seed Savers Exchange is by far the most comprehensive and useful book on varieties of fruit trees and their history and performance.
