Red Sandalwood Tree Plant Care

Red Sandalwood Tree (Adenanthera pavonina) belongs to the Fabaceae family within the Adenanthera genus. Red Sandalwood Tree is native to southern Asia and northern Australasia. Red Sandalwood Tree is also known as Coralwood, Paternoster Tree, Peacock Flower.

Red Sandalwood Tree displays a tall, spreading tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Red Sandalwood Tree produces small, red flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Red Sandalwood Tree 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.

Red Sandalwood Tree thrives in full sun to partial shade.

Adenanthera pavonina tolerates temperatures of 65–85°F. Red Sandalwood Tree 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. Good drainage is essential for Red Sandalwood Tree to prevent waterlogging, which leads to root rot and fungal issues.

Feed Red Sandalwood Tree 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 full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Red Sandalwood Tree 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.

Red Sandalwood Tree 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 Red Sandalwood Tree 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.

Red Sandalwood Tree 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.

Red Sandalwood Tree can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to adenanthera microsperma plant care, which shares the same genus.

Red Sandalwood Tree grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Red Sandalwood Tree is native to southern Asia and northern Australasia. In cooler regions, grow Red Sandalwood Tree as a houseplant or bring it indoors before the first frost.
