Terminalia alata Plant Care

Terminalia alata (Terminalia alata) belongs to the Combretaceae family within the Terminalia genus. Terminalia alata is native to southern and southeast Asia in India, Nepal, Bangladesh, Myanmar, Thailand, Laos, Cambodia, and Vietnam.

Terminalia alata displays a tall, spreading tree growth habit, reaching up to 50 ft tall with a spread of approximately 30 ft. Terminalia alata produces small, inconspicuous flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Terminalia alata 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.

Terminalia alata thrives in full sun to partial shade.

Terminalia alata tolerates temperatures of 60–85°F. Terminalia alata prefers humidity levels of 40–70%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Terminalia alata to prevent waterlogging, which leads to root rot and fungal issues.

Feed Terminalia alata 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Terminalia alata is suited to USDA Zone 10a – 12b.

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.

Terminalia alata can spread to about 30 ft (9.1 m) and reach about 50 ft (15 m) tall. Space plants about 30 ft (9.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Terminalia alata 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.

Terminalia alata is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Terminalia alata can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to grey terminalia plant care, which shares the same genus.

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

Terminalia alata grows outdoors in USDA Zone 10a – 12b. It survives winters down to planting zone 10a. Terminalia alata is native to southern and southeast Asia in India, Nepal, Bangladesh, Myanmar, Thailand, Laos, Cambodia, and Vietnam. In cooler regions, grow Terminalia alata as a houseplant or bring it indoors before the first frost.
