Ecology
- Leyland cypress tolerates most soil types, including clay, loam, and sand, acidic, and alkaline. It also tolerates drought and brief waterlogging.
Management
- To help its roots get established after spring or summer planting, water your Leyland cypress regularly. A Leyland cypress will take a few months to get established. After that, apply 1 gallon a week to the rootball if you live in USDA zones 7 or 8 and 2 gallons a week if you live in USDA zones 9 or 10. For the first and second years, water your Le...
Cultivation
- Leyland cypress trees are best grown in planting zones 6 to 10 with temperature lows of -8 degrees Fahrenheit. However, zone-5 gardeners have been successfully growing them by providing mulch and an A-frame shelter in the winter months to protect them from snow and ice damage. Such sheltering is feasible only while the plants are young (unless you keep them shor…
Culture
- Their height can be controlled (you can grow them as multi-stemmed shrubs), but only through persistent pruning that starts when the plants are young. Trim the sides of Leyland cypress trees every year in July.
Prevention
- After the leader has reached the height you want the tree to retain, make a pruning cut a few inches below that (which will leave room for the vertical growth of minor branches) to preclude any further significant upward growth, as you would do when pollarding a tree.
Uses
- A common landscape use is planting several Leyland cypresses along a border, in order to create a privacy screen. They are also used as windbreak trees. Since they are amenable to shearing or pruning, some homeowners take this a step further and turn such a border planting into a formal hedge. In addition to these practical landscaping uses, these plants frequently are used as Chris…
Symptoms
- Be sure to prune them early and often, otherwise, due to their fast growth rate, they tend to get too tall too quickly and can overwhelm a landscape.
