Oreorhamnus serrulatus Plant Care

Oreorhamnus serrulatus (Oreorhamnus serrulatus) belongs to the Rhamnaceae family within the Oreorhamnus genus. Oreorhamnus serrulatus is native to Borneo and Sumatra.

Oreorhamnus serrulatus displays a compact, spreading shrub growth habit, reaching up to 3 ft tall with a spread of approximately 4 ft. Oreorhamnus serrulatus produces small clusters of inconspicuous greenish-white flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Oreorhamnus serrulatus every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Oreorhamnus serrulatus thrives in full sun to partial shade.

Oreorhamnus serrulatus tolerates temperatures of 60–80°F. Oreorhamnus serrulatus prefers humidity levels of 40–70%.

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

Feed Oreorhamnus serrulatus every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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 sandy loam with added organic matter. Avoid low spots where water collects after rain.

Oreorhamnus serrulatus is suited to USDA Zone 13a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Oreorhamnus serrulatus can spread to about 4 ft (1.2 m) and reach about 3 ft (1 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Oreorhamnus serrulatus 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 shrub in one year.

Oreorhamnus serrulatus 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.

Oreorhamnus serrulatus can be propagated through seeds, hardwood cuttings.

Oreorhamnus serrulatus grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Oreorhamnus serrulatus is native to Borneo and Sumatra. In cooler regions, grow Oreorhamnus serrulatus as a houseplant or bring it indoors before the first frost.
