Also Known As - Golden Leyland Cypress
The Castlewellan Leyland Cypress (Cupressocyparis x leylandii 'Castlewellan') is an amazing evergreen tree with a unique look and an attractive shape. It grows quickly once established, reaching a height of 8-15 ft. It has a pyramidal shape and glossy, dark-green foliage that turns into a bright golden color during the winter months. In addition, the dense foliage provides excellent wind protection and noise reduction. It also tolerates a wide range of soils, making it great for hedges and privacy screens. Furthermore, the Castlewellan Leyland Cypress exhibits superb disease and pest tolerance. With its all-year-round evergreen color and elegant form, it is an excellent choice for any garden.

watering

Castlewellan Leyland Cypress needs to be watered regularly, but should not be overwatered. Aim to water about 1-2 times per week in the summer months and approximately once a month in winter (in areas where temperatures drop below 30°F). Make sure to check the soil to assess the moisture content, as that can vary depending on the environment. It is important to make sure the soil drains well after watering, so be sure to water directly into the soil and avoid getting the foliage wet as this can lead to fungal issues.

sunlight

Castlewellan Leyland Cypress requires full sun to partial shade to thrive, ideally with 6 to 8 hours of direct sunlight per day. It is considered sun-tolerant and can survive in hotter climates so long as it is provided with adequate moisture. In cooler areas, however, it tends to do best if given partial shade from the hot afternoon sun. During the summer and fall months, it should receive at least 6 hours of direct sunlight per day, while in the winter months it can do with slightly less.

pruning

The Castlewellan Leyland Cypress is a tough and resilient evergreen conifer that requires regular pruning. Pruning should take place twice a year - once in early spring and again in late summer. In early spring, pruning should be done to maintain a desired size, a natural shape and to create a neat border. Pruning should also remove any dead, damaged, or diseased branches. In late summer, pruning should be done to control branch thickening. Removing some of the smaller old twigs and some of the longer branches will help to maintain air circulation and will ensure the plant has an open structure. As a general rule, pruning should be conservative - removing no more than a third of the branches of the tree in any 1 season. The sharp, thin cutting blades of pruning shears should be used to make clean cuts.
