An excellent reference for pruning anything. Lots of detail, helpful illustrations, discussions of pruning/training needs starting from initial planting through maturity. Includes sections on training plants onto pillars, trellises, pergolas, and on special training techniques like espalier.
There are multiple editions, including older versions from the American Horticultural Society and another from the Royal Horticultural Society. The current edition seems to be published by DK.
