Khaen Plant Care

Khaen (Dracaena kaweesakii) belongs to the Asparagaceae family within the Dracaena genus. Khaen is also known as Thai Dracaena.

Khaen displays an upright, tree-like growth habit, reaching up to 6 ft tall with a spread of approximately 3 ft. Khaen produces rarely flowers indoors, small white blooms in clusters.

Leaf size: approximately 18 inches.

Water a young or newly planted Khaen 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.

Khaen thrives in bright indirect to low light. Avoid placing Khaen in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Dracaena kaweesakii tolerates temperatures of 65–80°F. Khaen prefers humidity levels of 40–60%.

Well-draining, peat-based potting mix with perlite for aeration. Good drainage is essential for Khaen to prevent waterlogging, which leads to root rot and fungal issues.

Feed Khaen every 4 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 bright indirect to low light and well-draining, peat-based potting mix with perlite for aeration. Avoid low spots where water collects after rain.

Khaen is suited to USDA Zone 13b.

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.

Khaen can spread to about 3 ft (0.9 m) and reach about 6 ft (2 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Khaen 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.

Khaen is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Khaen can be propagated through stem cuttings, air layering. Similar propagation techniques also apply to corn plant plant care, which shares the same genus.

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

Khaen grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. In cooler regions, grow Khaen as a houseplant or bring it indoors before the first frost.
