It tolerates a wide range of sites and soils (from acid to alkaline, from clay to sand) as well as salt-laden winds, which makes it suitable for planting in coastal areas. The species is frost hardy and has survived frosts of up to -20°C in the Southwest ofthe United States. Growth rates are relatively high especially in moist, fertile soils and the plants respond well to trimming.pp.206-210enrooting hormonescallus formationplant propagationLeyland CypressseedlingsJournal Article
