White Meranti Plant Care

White Meranti (Shorea gratissima) belongs to the Dipterocarpaceae family within the Shorea genus. White Meranti is native to Sumatra, Borneo, Peninsular Malaysia, Singapore, Myanmar and Thailand. White Meranti is also known as Light Red Meranti.

White Meranti displays a tall canopy tree growth habit, reaching up to 100 ft tall with a spread of approximately 50 ft. White Meranti produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted White Meranti 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.

White Meranti thrives in full sun.

Shorea gratissima tolerates temperatures of 65–85°F. White Meranti 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 White Meranti to prevent waterlogging, which leads to root rot and fungal issues.

Feed White Meranti every 8 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 and well-draining loamy soil with high organic content. Avoid low spots where water collects after rain.

White Meranti 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.

White Meranti can spread to about 50 ft (15.2 m) and reach about 100 ft (30 m) tall. Space plants about 50 ft (15.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune White Meranti 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.

White Meranti 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.

White Meranti can be propagated through seeds, cuttings. Similar propagation techniques also apply to meranti plant care, which shares the same genus.

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

White Meranti grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. White Meranti is native to Sumatra, Borneo, Peninsular Malaysia, Singapore, Myanmar and Thailand. In cooler regions, grow White Meranti as a houseplant or bring it indoors before the first frost.
