Since the tree is a hybrid, the Leyland cypress is almost always sterile and propagated mainly from cuttings. Successful rooting is achieved most often with cuttings taken from trees less than 10 years old, or from new shoot growth on older trees.
January, February, or March are the best months to do the cutting. Cuttings should be 6 to 8 inches long and show some brown coloration in the lower part of the stem. Dip the end of the stem in a rooting hormone used for woody trees. Plant into a porous planting media. Maintain the cutting in a warm, humid environment. Once the plant develops roots, transplant into a gallon-sized container. After six to nine months, the plant should be ready for planting outside in the spring.
Leyland cypress trees are shallow-rooted, meaning they can topple over easily, and they are susceptible to canker, which are dead sections caused by fungus or bacteria. Clean any pruning tools between each cut to keep the disease from spreading.
