Book excerpt: How, when, and where to prune? The questions that beset every gardener never change, but the solutions do. The Pruning of Trees, Shrubs and Conifers recommends the best pruning techniques and practices. This unique encyclopedic treatment details the best pruning methods for more than 450 genera of trees, shrubs, conifers, and woody climbers. The A-Z format covers several thousand species, yet remains a manageable and practical reference. Kirkham clearly explains the reasons behind pruning techniques as well as how to apply them.
