Expert tips
The key tip
Fast-growing up to 15 m. Let it grow with minimal intervention—just straighten any deformed branches.
The common mistake
Pruning too often slows growth and can create an irregular shape.
The pro's trick
A single leader should dominate: if two stems emerge equally, remove the weaker one right away.
Care
Exposure
Leyland cypress thrives in full sun, receiving at least 6 hours of direct light daily. In very hot regions, it tolerates light afternoon shade. Good air circulation around the plant prevents fungal problems.
Watering
Water regularly during the first year after planting to promote root establishment. Once established, Leyland cypress tolerates relative drought well and requires little watering, except during prolonged heat waves. Avoid excessive moisture which can cause rot.
Soil
This conifer adapts to most well-draining, neutral to slightly acidic soils. Soil that is too compacted or waterlogged compromises plant health. Amending with coarse compost at planting improves drainage.
Pruning and shaping
Prune lightly in late summer or early autumn to control shape and maintain foliage density. Avoid severe cuts on old wood, which heals poorly. Regular, moderate maintenance is preferable to drastic pruning.
Fertilizer
Not very demanding, Leyland cypress requires only a light application of balanced fertilizer in spring each year. A layer of organic mulch at the base helps retain moisture and gradually enriches the soil.
Diseases and pests
Susceptible to root rot in poorly draining soil. The foliage can occasionally be affected by fungal diseases. Good aeration and optimal drainage significantly reduce these risks.
Did you know?
Leyland cypress is a natural hybrid resulting from a cross between Monterey cypress and Himalayan juniper, fortuitously discovered in the gardens of Leighton Hall castle in England. This hybrid's exceptional vigor made it one of Europe's fastest-growing conifers, capable of gaining more than a meter per year under good conditions. Some specimens became so imposing that they sparked passionate debates about height restrictions for hedges in British urban planning!
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
