Dialium orientale Plant Care

Dialium orientale (Dialium orientale) belongs to the Fabaceae family within the Dialium genus. Dialium orientale is native to Kenya, Somalia, and Tanzania.

Dialium orientale displays a tall canopy tree growth habit, reaching up to 60 ft tall with a spread of approximately 30 ft. Dialium orientale produces small, fragrant yellow or white flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Dialium orientale 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.

Dialium orientale thrives in full sun to partial shade.

Dialium orientale tolerates temperatures of 65–85°F. Dialium orientale prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Dialium orientale to prevent waterlogging, which leads to root rot and fungal issues.

Feed Dialium orientale 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 organic matter for moisture retention. Avoid low spots where water collects after rain.

Dialium orientale is suited to USDA Zone 10b – 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.

Dialium orientale can spread to about 30 ft (9.1 m) and reach about 60 ft (18 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 Dialium orientale 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.

Dialium orientale 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.

Dialium orientale can be propagated through seeds, grafting. Similar propagation techniques also apply to dialium eurysepalum plant care, which shares the same genus.

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

Dialium orientale grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Dialium orientale is native to Kenya, Somalia, and Tanzania. In cooler regions, grow Dialium orientale as a houseplant or bring it indoors before the first frost.
