Nothing about pruning is obvious; in fact, most of it is downright counterintuitive, says expert Cass Turnbull. This second edition of her definitive illustrated guide adds 40 percent new material, with more coverage of different kinds of trees, shrubs and ground covers and how to prune them for health and aesthetics. The book looks at evergreen and deciduous shrubs; bamboos and tea roses; rhododendrons, camellia and other tree-like shrubs; hedge plants like boxwood and heather; clematis, wisteria and all those vines; and includes detailed information on trees by species from dogwoods to weeping cherries. In her trademark witty style, Turnbull also addresses tools, landscape renovation and design errors and offers her amusing Ten Commandments for gardeners.
