Stemonoporus elegans Plant Care

Stemonoporus elegans (Stemonoporus elegans) belongs to the Dipterocarpaceae family within the Stemonoporus genus. Stemonoporus elegans is native to the southern slope of Adam's Peak.

Stemonoporus elegans displays a tall canopy tree growth habit, reaching up to 50 ft tall with a spread of approximately 30 ft. Stemonoporus elegans produces small white or cream-colored flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Stemonoporus elegans 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.

Stemonoporus elegans thrives in full sun to partial shade.

Stemonoporus elegans tolerates temperatures of 65–85°F. Stemonoporus elegans prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with high organic content. Good drainage is essential for Stemonoporus elegans to prevent waterlogging, which leads to root rot and fungal issues.

Feed Stemonoporus elegans 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 loamy soil with high organic content. Avoid low spots where water collects after rain.

Stemonoporus elegans 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.

Stemonoporus elegans 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 Stemonoporus elegans 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.

Stemonoporus elegans 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.

Stemonoporus elegans can be propagated through seeds, stem cuttings.

Stemonoporus elegans is susceptible to 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.

Stemonoporus elegans grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Stemonoporus elegans is native to the southern slope of Adam's Peak. In cooler regions, grow Stemonoporus elegans as a houseplant or bring it indoors before the first frost.
