Praised by The New York Times as "an indispensable guide for the homeowner and the professional," Tree Maintenance has been the definitive source on maintenance of North American landscape trees for over fifty years, an essential reference not only for arborists, nurserymen, and landscapearchitects, but for all homeowners who want to keep their trees healthy and pest free. The Seventh Edition, now named in honor of Dr. P. P. Pirone, who authored the first five editions and co-authored the sixth, has been revised to reflect the enormous amount of new information available since the last edition, including the latest techniques in selecting, planting, andprotecting trees. The authors explain how to evaluate the site (the soil, drainage, and exposure), how to select the right tree for that location, and how to prune, fertilize, and spray for pests. There is an extensive section on the diagnosis and control of tree pests and diseases, and on problemssuch as construction damage, gas injury, sunscald, leaf scorch, and air pollution. While the general structure of the sixth edition has been retained, there are several topics--notably hazardous trees and coping with tree pests and diseases--that have received greater attention than in previousversions of the book. The second half of the book comprises a systematic listing of the major landscape trees found in North America, describing the specific pests and diseases that attack each species. Well organized, clearly written, and beautifully illustrated with many new photographs, Pirone's Tree Maintenance is an encyclopedic resource, the first place to turn for information on dogwoods and elms, magnolias and redwoods, or any other tree growing in North America. Anyone serious aboutgardening will want this book on their shelf.
