Nootka cypress Plant Care

Nootka cypress (Callitropsis nootkatensis) belongs to the Cupressaceae family within the Callitropsis genus. Nootka cypress is native to the coastal regions of northwestern North America. Nootka cypress is also known as Yellow cypress, Alaska cypress, Nootka false cypress.

Nootka cypress displays a tall, conical tree growth habit, reaching up to 50 ft tall with a spread of approximately 15 ft. Nootka cypress produces small cones.

Water a young or newly planted Nootka cypress every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Nootka cypress thrives in full sun.

Callitropsis nootkatensis tolerates temperatures of 50–80°F. Nootka cypress prefers humidity levels of 40–60%.

Well-draining sandy soil with good aeration. Good drainage is essential for Nootka cypress to prevent waterlogging, which leads to root rot and fungal issues.

Choose a spot with full sun and well-draining sandy soil with good aeration. Avoid low spots where water collects after rain.

Nootka cypress is suited to USDA Zone 12a.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Nootka cypress can spread to about 15 ft (4.6 m) and reach about 50 ft (15 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Nootka cypress while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

Nootka cypress is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Nootka cypress can be propagated through seeds, cuttings.

Nootka cypress grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Nootka cypress is native to the coastal regions of northwestern North America. In cooler regions, grow Nootka cypress as a houseplant or bring it indoors before the first frost.
