Sun Requirements of Leyland Cypress. Commonly known as leylandii, the Leyland cypress provides year-round color. It is a popular species to plant in gardens of new houses because it grows very quickly and provides privacy from other neighbors. Leylandii also absorb high noise decibels and this makes them suitable trees to grow near busy roads.

Leylandii is a familiar sight in suburban gardens where it provides fast-growing boundary hedges, borders, windbreaks and screening. Despite its popularity, the species is the source of many neighbor disputes because it can grow up to 50 feet tall and 17 feet wide. If it is not pruned. it can block sunlight or easily topple over due to shallow roots.
Leylandii is a cross between the Alaskan cedar and Monterey cypress and is an evergreen conifer. This means it retains its leaves all year and produces small woody cones instead of flowers. As a hybrid cross, the first leylandii tree is thought to have grown in 1888 in the grounds of Leighton Hall, Wales, after two conifers were grown close to each other.
Sun and Growth
Ideally, the leylandii prefers full sun in well-drained soil but it is a hardy species and can also thrive in poor soils and shade and will tolerate pollution. During the first year, it will only grow 1 foot tall while the root system is being established but after this period, it typically grows 3 to 4 feet per year.
Pests and Diseases
Reddy-brown branches are the sign of a fungal disease known as canker that can cause branches to wither and die. Leylandii also suffer from needle blight that makes needles go brown and fall off. It is common following periods of damp and windy weather as they provide the perfect conditions for infectious spores to spread and multiply.
In 2000, a Welsh resident was shot dead after an argument with his neighbor over a leylandii hedge that had grown 6 foot high. In 2005, a new law was introduced by the British government called Leylandii Law. It granted local councils the power to cut down leylandii trees if they were proven to be a nuisance to neighbors.
