Red Bean Tree Plant Care

Red Bean Tree (Archidendron pauciflorum) belongs to the Fabaceae family within the Archidendron genus. Red Bean Tree is native to Southeast Asia. Red Bean Tree is also known as Pink Bean Tree.

Red Bean Tree displays a tall tree, spreading canopy growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Red Bean Tree produces showy clusters of small yellow flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Red Bean 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 Bean Tree thrives in full sun to partial shade.

Archidendron pauciflorum tolerates temperatures of 60–85°F. Red Bean Tree prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, slightly acidic soil mix with added organic matter. Good drainage is essential for Red Bean Tree to prevent waterlogging, which leads to root rot and fungal issues.

Feed Red Bean 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, slightly acidic soil mix with added organic matter. Avoid low spots where water collects after rain.

Red Bean Tree 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.

Red Bean 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 Bean 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 Bean Tree 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.

Red Bean Tree can be propagated through seeds, grafting. Similar propagation techniques also apply to bigeminum archidendron plant care, which shares the same genus.

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

Red Bean Tree grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Red Bean Tree is native to Southeast Asia. In cooler regions, grow Red Bean Tree as a houseplant or bring it indoors before the first frost.
