For more than 20 years this essential reference has been the bible for Australian students of horticulture--and for practicing horticulturists, groundskeepers, landscapers, and gardeners. With 42 new illustrations, this updated edition has been substantially revised to include the latest advances in horticultural production, with significant revisions to chapters on soil-borne diseases, fertilizers, nursery practices, turf irrigation, and drainage. Other additions to the book include plans for roof gardens, vertical gardens, and water-recycling projects.
