Sea Poison Tree grows best in a fertile, humid, well-drained soil. It prefers a position in full sun or light shade. Established plants are fairly drought tolerant and very tolerant of saline conditions and salt-laden winds. They thrive in the wild, where their roots dabbling in the brackish waters of lagoons, inlets, estuaries, and seasonally flooded coastal regions.

New plants are usually grown from seed. It performs best on free-draining sand and loam soils of a slightly acid to alkaline nature, generally with a pH of 6.0 to 8.5 and on sites with full sun exposure. It has good tolerance to salt, wind, tidal flooding, and coral derived limestone soils. See more at How to Grow and Care for a Sea Poison Tree (Barringtonia asiatica).
