Mauritius Plum Plant Care

Mauritius Plum (Psiloxylon mauritianum) belongs to the Myrtaceae family within the Psiloxylon genus. Mauritius Plum is native to the Mascarene Islands in the Indian Ocean.

Mauritius Plum displays a tall, upright tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Mauritius Plum produces small white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Mauritius Plum 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.

Mauritius Plum thrives in full sun to partial shade.

Psiloxylon mauritianum tolerates temperatures of 60–85°F. Mauritius Plum prefers humidity levels of 40–70%.

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

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

Mauritius Plum 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.

Mauritius Plum can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Mauritius Plum 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.

Mauritius Plum 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.

Mauritius Plum can be propagated through seeds, cuttings.

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

Mauritius Plum grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Mauritius Plum is native to the Mascarene Islands in the Indian Ocean. In cooler regions, grow Mauritius Plum as a houseplant or bring it indoors before the first frost.
