False Mastic Plant Care

False Mastic (Margaritaria nobilis) belongs to the Phyllanthaceae family within the Margaritaria genus. False Mastic is native to Mexico, Central America, South America, and the West Indies. False Mastic is also known as Pigeonwood, Bulletwood.

False Mastic displays a small tree, spreading canopy growth habit, reaching up to 15 ft tall with a spread of approximately 10 ft. False Mastic produces small greenish-yellow flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted False Mastic 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.

False Mastic thrives in full sun to partial shade.

Margaritaria nobilis tolerates temperatures of 65–85°F. False Mastic prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

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

Feed False Mastic 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 for nutrients. Avoid low spots where water collects after rain.

False Mastic is suited to USDA Zone 13b – 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.

False Mastic can spread to about 10 ft (3 m) and reach about 15 ft (5 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune False Mastic 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.

False Mastic 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.

False Mastic can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to false mastic plant care, which shares the same genus.

False Mastic 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.

False Mastic grows outdoors in USDA Zone 13b – 12b. It survives winters down to planting zone 13b. False Mastic is native to Mexico, Central America, South America, and the West Indies. In cooler regions, grow False Mastic as a houseplant or bring it indoors before the first frost.
