Book excerpt: Over the years, Japanese gardeners have fine-tuned a distinctive set of pruning techniques that coax out the essential characters of their garden trees, or niwaki. In this highly practical book, Western gardeners are encouraged to draw upon the techniques and sculpt their own garden trees to unique effect. After first discussing the principles that underpin the techniques, the author offers in-depth guidelines for shaping pines, azaleas, conifers, broadleaved evergreens, bamboos and deciduous trees. Throughout the text, step-by-step illustrations accompany the instructions, while abundant photographs and anecdotes bring the ideas surrounding niwaki vividly to life.
