The director of Cheyenne Botanic Gardens and author of The Bountiful Solar Greenhouse has produced a practical, comprehensive guide to making the most of any greenhouse or garden room. Addressing almost every aspect except the actual construction, Smith covers the greenhouse environment (light, humidity, temperature), interior design (plant placement, fans, drainage), individual plants and their propagation, pollination, growth, and scheduling for flower or fruit production. There are chapters on problems, diseases, and insects, and lists of associations, mail-order suppliers, and sun averages during the year across the country. As a Wyoming gardener, he puts a good deal of emphasis on using the greenhouse in summer as well as in winter, but this is a useful, practical guide for readers in most of the continental United States.
