About soil condition, leyland cypress grows well in a wide range of soils as long as the soil is well-drained. It is tolerant of both dry and wet soils, but it does not tolerate discrimination soils. The tree also does not do well in heavy, dense clay soils. Leyland cypress prefers soils that are rich in organic matter.
So, like the other evergreens, Leyland cypress (x Cupressocyparis leylandii) need sun to grow well and stay healthy. This fast-growing tree is often used as a hedge or privacy screen, so it's important to plant it in an area that gets at least six hours of direct sunlight each day. In shady areas, the tree may grow more slowly and be more susceptible to diseases.
The temperature conditions that are most favorable for Leyland cypress growth are those that are within the range of 60 to 80 degrees Fahrenheit. This plant is not tolerant of high temperatures, and prolonged exposure to temperatures above 80 degrees Fahrenheit can cause leaf scorching and needle drop. In addition, this species is not tolerant of frost, and temperatures below 60 degrees Fahrenheit can damage or kill the plant.
Ideal humidity condition for this plant is between 40 and 60 percent. The roots of the plant are very sensitive to over-watering, so be sure to allow the topsoil to dry out between watering. If the leaves of the plant begin to turn brown, this is a sign that it is not getting enough water.
About fertilizer, usually the plant doesn't need too much. An annual feeding in spring is usually sufficient. As for the roots, they are relatively shallow and close to the surface. Because of this, the plant is not particularly drought tolerant.
Pruning is an important part of caring for a leyland cypress. The tree will need to be pruned regularly to keep it looking its best. When pruning, be sure to remove any dead or dying branches. You should also trim back any branches that are growing too close to the trunk of the tree.
Propagation of Leyland cypress is usually by cuttings taken from young, healthy plants in late spring or early summer. The cuttings should be about 6 inches (15 cm) long and should be taken from the tips of the branches. They should be placed in a planting mix that is well-drained and kept moist until they have rooted. Leyland cypress can also be propagated by seed, but it is often difficult to get the seeds to germinate.
Usually, the plant growth rate during their first 10 years of life. After that, growth slows considerably. In the wild, these trees may live to be 150 years old, but in cultivation, they are more likely to live 50 to 70 years. Given the rapid growth of these trees during their first decade, it is important to provide them with plenty of space so they do not crowd out other plants in the landscape.
Common problems for this kind of plant are fungal diseases, such as canker and root rot. These diseases can kill the tree if left untreated. Other problems include pests, such as caterpillars and scale insects, which can damage the tree's foliage.
