How to Grow a Tall Leyland Cypress

Overview

The Leyland cypress is an evergreen that grows best in USDA hardiness zone 6 and higher. The tree is fast growing with a mature height of 50 feet and spread of 25 feet when cared for properly. Choose to plant Leyland cypress trees in open landscapes instead of small residential areas, as the tree will outgrow small space surroundings when left to grow tall. Leyland cypress trees have soft needle foliage and grow well as a Christmas tree variety or planted as a hedge.

Step 1

Select a planting area for the Leyland cypress that has no overhead wires that will prevent the tree from growing tall. Make sure the area receives full sunlight and has a well-draining soil.

Step 2

Plant the Leyland cypress in a hole that is twice as wide and the same depth as the container the tree came in. Work equal portions of organic compost into the removed soil to increase the nutrient content for tree growth.

Step 3

Apply 3 to 4 inches of organic mulch around the base of the tree and over the root ball to increase moisture retention, which prevents the tree from drying out. Start the mulch 6 inches from the trunk of the tree to prevent excess moisture build up around the trunk.

Step 4

Provide supplemental water to the Leyland cypress tree by applying 1 to 2 inches of water through drip irrigation when the weekly rainfall is less than 1 inch.

Step 5

Apply a balanced tree fertilizer to the Leyland cypress each spring to provide nutrients for growth. Place the fertilizer 12 inches from the trunk and apply water to assist with absorption. Follow the application instructions listed on the package based on the height of the tree.

Step 6

Remove dead and damaged branches from the Leyland cypress with a clean pruning clipper in early spring before the flush of growth. Leyland cypress trees do not require pruning to maintain shape or stimulate growth.
