For more than twenty years, ""Growing Media for Ornamental Plants and Turf"" has been a core text for students of horticulture and an essential reference for practicing horticulturists, their suppliers, green keepers, landscape gardeners and designers. With 42 new illustrations, this fourth edition has been substantially revised and updated to include the latest advances in horticultural production systems, with significant revisions to chapters on fertilizer practice in nurseries, foundations for good turf, managing turf soil, fertilizing turf irrigation, and drainage. New additions include discussion on roof gardens and vertical gardens, and topics on recycled water for irrigation and issues of water shortage have been expanded.
