Lealand cypress trees, more commonly called Leyland cypress, are a fast-growing evergreen capable of reaching a height of 35 to 50 feet and width of 15 to 25 feet. Leyland cypress can be used to create privacy hedges. It is cold hardy in USDA zones 6 through 10a. Tolerant of salt spray, Leyland cypress is suitable for beach cottages.
Choose a sunny, well-drained location. Leyland cypress can be planted any time of the year as long as the soil is not frozen. Spring and fall the optimal times for planting.
Dig the hole twice as wide as the root ball or container. Dig the hole as deep as the root ball or container is tall. If planting more than one Leyland cypress to create a privacy hedge, space the holes 15 to 20 feet apart.
Dig down about 6 inches deeper in clay soil, amend the soil with about 25 percent topsoil, and return the soil mixture to the hole. Organic matter, like compost or leaf mold, can be substituted for topsoil
Keep the ball and burlap wrapped, but remove the potted Leyland cypress from the container. Place the plant in the center of the hole.
Backfill the hole halfway with the removed soil. Water to settle the soil. Release the burlap and pull it down to expose the top half of the root ball. Finish backfilling the hole.
Water thoroughly, and then water every 10 days the first year. After the first year, rainfall should be sufficient to water the Leyland cypress except in dry periods, when it should receive 1 inch of water every 7 to 14 days.
Pruning is only needed to control height or width. Prune in late winter. Immediately prune diseased or dead branches, recognizable by brown needles, by cutting back at least 3 inches into healthy wood.
