Barringtonia lanceolata Plant Care

Barringtonia lanceolata (Barringtonia lanceolata) belongs to the Lecythidaceae family within the Barringtonia genus. Barringtonia lanceolata is native to Borneo.

Barringtonia lanceolata displays a tall, spreading tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Barringtonia lanceolata produces showy, fragrant flowers in shades of pink, white, or red.

Leaf size: approximately 8 inches.

Water a young or newly planted Barringtonia lanceolata 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.

Barringtonia lanceolata thrives in full sun to partial shade.

Barringtonia lanceolata tolerates temperatures of 65–85°F. Barringtonia lanceolata prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

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

Feed Barringtonia lanceolata 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 for moisture retention. Avoid low spots where water collects after rain.

Barringtonia lanceolata is suited to USDA Zone 13b.

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.

Barringtonia lanceolata 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 Barringtonia lanceolata 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.

Barringtonia lanceolata 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.

Barringtonia lanceolata can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to sea poison tree plant care, which shares the same genus.

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

Barringtonia lanceolata grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Barringtonia lanceolata is native to Borneo. In cooler regions, grow Barringtonia lanceolata as a houseplant or bring it indoors before the first frost.
