When Can You Plant Leyland Cypress Trees?

If you're looking for a fast-growing, evergreen tree with attractive foliage, the Leyland Cypress is an excellent choice. Named after the location it was first hybridized, the Leighton Hall in Wales, Leyland Cypress has become a popular choice for privacy screens, windbreaks, and landscapes.

The Best Time to Plant Leyland Cypress Trees

The best time to plant Leyland Cypress trees is in the late fall or winter, though planting can continue through early spring. Early planting allows the tree's roots to establish before the onset of new growth in the spring. It also reduces the amount of water the tree requires because cooler weather demands less moisture.

Though fall is the best time to plant, gardeners who cannot plant during this time can plant Leyland Cypress trees in spring as well. Trees planted in spring require more moisture to establish because the sun is higher in the sky and warms the soil quicker, so water regularly during the first year.

Factors to Consider When Planting Leyland Cypress

Before planting Leyland Cypress trees, several factors must be considered. The first thing to consider is the location of the trees. Leyland Cypress trees prefer full sun exposures, but they can tolerate partial shade in hot climates. They also prefer well-drained soils, acidic to slightly alkaline soil, and will not thrive in waterlogged soils.

It's also crucial to consider spacing when planting Leyland Cypress. Space trees at least 10 feet apart when planting for windbreaks or privacy screens. When planting for landscapes, space trees according to their mature size, which can reach up to 70 feet tall and 15 to 25 feet wide. By spacing trees correctly, you create maximum growth and reduce competition for water, nutrients, and sunlight.

Planting Leyland Cypress Trees

When planting Leyland Cypress trees, dig a hole that is twice the width of the root ball but no deeper than the size of the root crown. Gently remove the tree from its container and trim any damaged or broken roots before planting. If the tree is rootbound, score the sides of the root ball to encourage root expansion.

After placing the tree in the hole, backfill the hole with topsoil, tamping periodically to remove air pockets. Add a layer of mulch around the base of the tree, avoiding the stem to prevent moisture buildup, which can lead to fungus and other diseases.

Caring for Leyland Cypress Trees

For the first year after planting, water Leyland Cypress trees once or twice a week, providing one inch of water every week. During hot and dry weather, increase watering as needed to prevent water stress. Apply a balanced fertilizer in early spring and mid-summer for the first year after planting. After that, fertilize annually in the spring with a slow-release fertilizer to encourage growth and development.

Prune Leyland Cypress trees in late winter or early spring to keep the trees' size and shape. Avoid pruning in the fall because it can attract pests like bark beetles, which can infest the tree and cause damage. Leyland Cypress trees can also be vulnerable to spider mites, aphids, and bagworms, so monitor trees regularly for signs of pests and treat as needed.

Conclusion

Leyland Cypress is an excellent choice for a fast-growing, evergreen tree that provides privacy screens and windbreaks. When planting Leyland Cypress trees, consider the location, spacing, and soil conditions to ensure that the trees thrive. With proper care and maintenance, Leyland Cypress trees can flourish and add beauty to any landscape.
