Melliodendron xylocarpum Plant Care

Melliodendron xylocarpum (Melliodendron xylocarpum) belongs to the Styracaceae family within the Melliodendron genus.

Melliodendron xylocarpum displays a medium-sized deciduous tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Melliodendron xylocarpum produces small white fragrant flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Melliodendron xylocarpum 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.

Melliodendron xylocarpum thrives in full sun to partial shade.

Melliodendron xylocarpum tolerates temperatures of 60–80°F. Melliodendron xylocarpum prefers humidity levels of 40–70%.

Well-draining loamy soil with added organic matter like compost or peat moss. Good drainage is essential for Melliodendron xylocarpum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Melliodendron xylocarpum 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 added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Melliodendron xylocarpum is suited to USDA Zone 13a.

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.

Melliodendron xylocarpum 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 Melliodendron xylocarpum 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.

Melliodendron xylocarpum 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.

Melliodendron xylocarpum can be propagated through seeds, softwood cuttings.

Melliodendron xylocarpum is susceptible to aphids, 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.

Melliodendron xylocarpum grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Melliodendron xylocarpum as a houseplant or bring it indoors before the first frost.
