White Mahogany Plant Care

White Mahogany (Dysoxylum latifolium) belongs to the Meliaceae family within the Dysoxylum genus. White Mahogany is native to New Guinea, the Solomon Islands, and the Australian states of Western Australia, Northern Territory and Queensland. White Mahogany is also known as Australian Rose Mahogany.

White Mahogany displays a tall canopy tree growth habit, reaching up to 50 ft tall with a spread of approximately 20 ft. White Mahogany produces small, fragrant white flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted White Mahogany 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 Mahogany thrives in partial to full sun.

Dysoxylum latifolium tolerates temperatures of 65–85°F. White Mahogany prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich loamy soil with added compost for nutrients. Good drainage is essential for White Mahogany to prevent waterlogging, which leads to root rot and fungal issues.

Feed White Mahogany 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 partial to full sun and well-draining, rich loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

White Mahogany is suited to USDA Zone 10b – 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.

White Mahogany can spread to about 20 ft (6.1 m) and reach about 50 ft (15 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 White Mahogany 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 Mahogany is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

White Mahogany can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to dysoxylum gaudichaudianum plant care, which shares the same genus.

White Mahogany 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.

White Mahogany grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. White Mahogany is native to New Guinea, the Solomon Islands, and the Australian states of Western Australia, Northern Territory and Queensland. In cooler regions, grow White Mahogany as a houseplant or bring it indoors before the first frost.
