Meet the Lemon Cypress

The lemon cypress, also called the Monterey cypress, is a striking evergreen. These popular ornamentals are grown for their bright chartreuse foliage colors. With their informal habit, these cypress trees make good lawn specimens. Several cultivars (including Goldcrest Wilma and Goldcrest) offer a smaller presentation and even more brilliant coloration. They can be grown in a container or in a garden bed.

Lemon Cypress Care

Lemon cypress trees are easy-to-grow plants. They offer bright yellow foliage color and their informal habit. These cypress trees are often grown as lawn specimens and will stand up to salt wind.

Light

Lemon cypress care begins with having a good placement. These trees can thrive in either full, direct sun or partial shade. This means either a site with at least 6 hours of direct sunlight each day, or a site with between 2 and 6 hours a day. 

Water

As with most trees, lemon cypress trees require regular irrigation when they are first planted. However, they are drought tolerant once established and those planted in the garden bed do not require irrigation more than once a week during the growing season. However, container plants will need more regular irrigation.

Temperature & Humidity

Care of lemon cypress is fairly easy in the correct location. Lemon cypress is hardy down to USDA zone 7 and up to zone 11. 

Soil

These trees tolerate a wide range of types of soil and acidity. However, they require well-drained soil. 

Fertilizer

Lemon cypress trees grow well without fertilizer and it is not recommended..

Problems, Pests & Diseases

Lemon cypress can be vulnerable to strong winds. They grow quickly, especially when grown in rich soil, which should be avoided. 

These plants can be vulnerable to several pests and diseases. These include borers. Armillaria, Phytophthora, root rot, and coryneum canker.

Tips for Planting a Lemon Cypress Tree

Lemon cypress, especially the dwarf cultivar, grows easily in containers. They can also be planted in the landscape in an area that gets adequate direct sun. Well-draining soil is essential, but avoid rich soils since the plant’s growth rate in rich soil can encourage a vulnerability to wind damage.

Pruning

Lemon cypress trees require little if any pruning. The sole exception is cypress grown as hedges that need trimming. 

Propagation

Yellow cypress are conifers that produce seeds in their cones. These seeds can be used for propagation. However, if you own a cultivar, propagating from seed will not produce a plant with the same features as the parent. It is also possible to propagate from stem cuttings taken in winter.

Repotting Lemon Cypress Trees

If you decide to grow lemon cypress in a container, it may be necessary to repot the tree from time to time. Every three to four years, move the cypress to a container at least one inch (2.5 cm) wider than the old pot and backfill with fresh potting mix.

Lemon Cypress Varieties

The most popular lemon cypress cultivars are Gold Crest and Goldcrest Wilma. The former grows relatively quickly (at about 10 inches (25 cm)  a year) to 40 feet (12 m).  The Goldcrest Wilma cultivar is a dwarf selection of the cultivar Gold Crest. It matures to 6 feet (1.8 m) tall.
