Leyland cypress has become one of the most widely used plants in commercial and residential landscapes across Georgia as a formal hedge, screen, buffer strip or wind barrier. Leyland cypress (x Cupressocyparis leylandii) is a graceful, rapidly growing evergreen tree that is adapted for growth within the 6-10a USDA hardiness zones. Leyland cypress is considered relatively pest-free; however, because of its relatively shallow root system, and because they are often planted too close together and in poorly drained soils, Leyland cypress is prone to root rot and several damaging canker diseases, especially during periods of prolonged drought. Disease management is, therefore, a consideration for Leyland cypress.
