Semecarpus subpeltata Plant Care

Semecarpus subpeltata (Semecarpus subpeltata) belongs to the Anacardiaceae family within the Semecarpus genus. Semecarpus subpeltata is native to Sri Lanka.

Semecarpus subpeltata displays a medium-sized tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Semecarpus subpeltata produces small greenish-yellow flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Semecarpus subpeltata 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.

Semecarpus subpeltata thrives in full sun to partial shade.

Semecarpus subpeltata tolerates temperatures of 60–85°F. Semecarpus subpeltata prefers humidity levels of 40–70%.

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

Feed Semecarpus subpeltata 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 sandy loam with added organic matter. Avoid low spots where water collects after rain.

Semecarpus subpeltata is suited to USDA Zone 11a – 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.

Semecarpus subpeltata can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Semecarpus subpeltata 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.

Semecarpus subpeltata is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Semecarpus subpeltata can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to burmese marking nut plant care, which shares the same genus.

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

Semecarpus subpeltata grows outdoors in USDA Zone 11a – 12b. It survives winters down to planting zone 11a. Semecarpus subpeltata is native to Sri Lanka. In cooler regions, grow Semecarpus subpeltata as a houseplant or bring it indoors before the first frost.
