ABOUT

× Cuprocyparis notabilis, more commonly known as Leyland Cypress, is a coniferous evergreen that is well known for its dense, compact foliage. Its leaves are scale-like, with a rich green color that adorns the flattened sprays of its branches. These leaves can sometimes present a slightly bluish or grayish green hue, depending on the variety and growing conditions. The overall shape of the Leyland Cypress is generally pyramidal to columnar, giving it a stately and formal appearance that is favored in many landscape designs. The bark of this plant is usually a reddish-brown color, which fissures with age and can add textural interest to the visual profile of the tree. It produces small, rounded cones, usually not longer than an inch, which are green when young and turn brown as they mature. The Leyland Cypress has a vigorous growth habit and displays a symmetrical, densely foliated form. It offers excellent coverage and is often used for privacy screens or windbreaks as a result. The appearance of the Leyland Cypress can vary based on pruning and maintenance practices, allowing for a range of uses in both residential and commercial landscaping. Its broad, sweeping branches create a soft yet full silhouette, with the year-round color making it a popular choice for those seeking an evergreen planting solution.

Pruning
  • water dropWater

    The Leyland Cypress, which is the most common common name for × Cuprocyparis notabilis, requires consistent moisture but doesn’t do well with overwatering. Ensure the soil is well-draining and water the plant deeply when the top few inches of soil feel dry to the touch, which usually amounts to once a week during hot dry weather. In cooler temperatures or when rainfall is abundant, watering frequency can be reduced. Provide about 1 to 2 gallons per watering for young trees, increasing the amount as the tree matures and depending on the size and environmental conditions.

  • sunLight

    The Leyland Cypress thrives in full sunlight, which means it should receive at least 6 hours of direct sun per day. It's best to place the plant in an open area where it is not overshadowed by taller structures or trees. This sun-loving conifer will perform well and grow dense foliage when situated in a spot that meets its light exposure needs.

  • thermometerTemperature

    Leyland Cypress is hardy and can tolerate a temperature range from down to about 0°F to up above 100°F, but it thrives best in temperatures between 50°F and 80°F. Sudden drops below freezing can be harmful especially to young plants, so providing some wind protection can help in managing temperature stress.

  • scissorsPruning

    Prune Leyland Cypress for shape and size management in late winter or early spring before new growth starts. Pruning may also be necessary to remove dead or damaged branches which can be done at any time of year. Annual pruning helps maintain the desired height and density of the hedge or tree, improving air circulation and enhancing the plant's overall health.

  • bambooSoil

    Leyland Cypress thrives in well-draining soil with a pH between 5.5 and 7.0. The best soil mix for this tree is a blend of loam, peat, and sand to ensure proper drainage and aeration. Slight acidity to neutral pH is ideal for nutrient absorption.

  • plantRepotting

    Leyland Cypress trees, being large and potentially fast-growing, do not typically require frequent repotting. They are usually planted directly in the ground. However, if grown in containers, repotting every 2-3 years or when rootbound is recommended to ensure sufficient space for root growth.

  • circleLife cycle

    × Cuprocyparis notabilis, commonly known as Leyland Cypress, begins its life with the germination of a hybrid seed, which requires a warm, moist environment to sprout. The seedling then develops into a juvenile plant featuring a single leader and horizontal branching, characteristic of its coniferous nature. As the Leyland Cypress matures, it undergoes a period of rapid vertical growth, often gaining several feet per year, and its evergreen foliage becomes dense, creating a conical or columnar shape. Once the tree reaches reproductive maturity, it produces small, round cones that contain the seeds for the next generation, although reproducing true to type might be limited due to its hybrid nature. The Leyland Cypress, being a long-lived tree, can remain in its mature stage for several decades, providing screening and ornamental value. Eventually, the tree enters a senescence phase, where growth slows and it becomes more susceptible to diseases and environmental stresses, leading ultimately to its decline and death.

      Spring-Early Summer

    • The Leyland cypress, scientifically known as × Cuprocyparis leylandii, is most commonly propagated by cuttings. This method is popular due to its simplicity and high success rate. To propagate the Leyland cypress by cuttings, take a 4 to 6 inch (approximately 10 to 15 centimeters) cutting from the current year's growth during the late fall or early winter when the tree is dormant. Ensure the cutting includes at least one set of leaves or nodes. Dip the cut end in rooting hormone to encourage root development and plant it in a well-draining soil mix. Keep the soil consistently moist and provide indirect light until the cutting has rooted, which can take a few weeks to a few months. Once rooted, the new Leyland cypress can be transplanted to a more permanent location in the garden.
