Leyland cypress (Cupressocyparis leylandii) trees are fast growing evergreen trees. They grow up to four feet a year and can be used as a single specimen tree or planted in a line and used as a windbreak. Also, Leyland cypress trees can be planted in a row and trained as a hedge. They are hardy in the Southern half of the United States and grow best in well-drained soil. The Leyland cypress grows to 40 feet tall and 30 feet wide.
Choose a Leyland cypress to plant that has soft green foliage that does not look dried or stressed. Look for brown areas on the foliage that indicate disease. The surface roots in the pot should not be exposed or circling around the inside of the pot and the soil in the container should be moist.
Locate a place in the landscape that receives full sun, or at least six hours of direct sun each day, and is well drained. A Leyland cypress cannot grow in water logged soil. Because of the eventual large size and the rapid growth rate, be sure you find an area that is suitable for a large tree. Also, keep in mind that plants and lawn grass have trouble growing in dense evergreen shade.
Dig a hole with a shovel that is as deep as the plant is in the pot and twice as wide as the container. You don't want the plant to be placed in the ground deeper than it is planted in the container. If there is heavy clay in the planting hole, pulverize the clay as much as possible.
Pull the Leyland cypress from the pot and immediately place the root ball into the planting hole. If the hole is too deep, then remove the plant and place dirt in the hole to adjust the depth of the hole. Once the tree is in the hole, spread out any roots so the roots cannot grow in a circle around the root ball.
Fill in the hole around the roots of the Leyland cypress with the same dirt that was removed from the hole. There is no need to add any amendments while planting because the tree needs to become accustomed to the native soil as soon as possible. Mix water with the soil as you add it into the hole to prevent the formation of air spaces around the root system. After the root base is covered, add a one-inch layer of mulch around the root base of the Leyland cypress to protect the roots and prevent wide fluctuation in moisture levels.
