Brazillian Mahogany Plant Care

Brazillian Mahogany (Astronium gardneri) belongs to the Anacardiaceae family within the Astronium genus. Brazillian Mahogany is native to Brazil, Colombia, Ecuador. Brazillian Mahogany is also known as Amendoim.

Brazillian Mahogany displays a tall, spreading tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Brazillian Mahogany produces small clusters of greenish-white flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Brazillian 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.

Brazillian Mahogany thrives in full sun to partial shade.

Astronium gardneri tolerates temperatures of 60–85°F. Brazillian Mahogany prefers humidity levels of 40–70%.

Well-draining loamy soil mix with added organic matter for moisture retention. Good drainage is essential for Brazillian Mahogany to prevent waterlogging, which leads to root rot and fungal issues.

Feed Brazillian 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.

Choose a spot with full sun to partial shade and well-draining loamy soil mix with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Brazillian 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.

Brazillian Mahogany 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 Brazillian 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.

Brazillian 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.

Brazillian Mahogany can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to brazillian mahogany plant care, which shares the same genus.

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

Brazillian Mahogany grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Brazillian Mahogany is native to Brazil, Colombia, Ecuador. In cooler regions, grow Brazillian Mahogany as a houseplant or bring it indoors before the first frost.
