Khat Plant Care

Khat (Catha edulis) belongs to the Celastraceae family within the Catha genus. Khat is native to East and Southeastern Africa. Khat is also known as Miraa, Qat, Chat.

Khat displays a medium-sized evergreen tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Khat produces small white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Khat 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.

Khat thrives in full sun to partial shade.

Catha edulis tolerates temperatures of 60–85°F. Khat prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Khat to prevent waterlogging, which leads to root rot and fungal issues.

Feed Khat every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Khat is suited to USDA Zone 9b – 11b.

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.

Khat can spread to about 15 ft (4.6 m) and reach about 20 ft (6 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 Khat 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.

Khat is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Khat can be propagated through seeds, stem cuttings.

Khat is susceptible to aphids, scale insects, caterpillars. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Khat grows outdoors in USDA Zone 9b – 11b. It survives winters down to planting zone 9b. Khat is native to East and Southeastern Africa. In cooler regions, grow Khat as a houseplant or bring it indoors before the first frost.
