The Q&A Archives: Location For An Emerald Isle Leyland Cypress

Question: I bought 3 Em. Isle Leyland cypress to put in my front yard to replace 3 other 8ft., groomed junipers(that were killed by spider mites.) But now I am a little concerned that they may grow too large for the area. The area that I have is in full sun, but only 2-3 feet away from my house. There are also other 2-3ft tall shrubs in the same bed. Can this type of Evergreen be trimmed so that they don't get too wide and too tall and still keep a decent shape and appearance?

Answer: Cupressus leylandii 'Moncal', the Emerald Isle, is a fast-growing, 20-25' tall evergreen, perfect for windbreaks or tall screens. The ultimate width of the plant is 6'-8'. When they reach maturity, they may be to large for the area you describe. Annual pruning will keep them small for a few years, but eventually they'll become too large to keep under control. A better choice for the garden bed is Swane's Golden Italian Cypress (Cupressus sempervirens 'Swane's Golden'). This is a narrow, columnar evergreen with a mature height of 15-20' and a width of 2-3'
