Sonneratia griffithii is a mangrove species, requiring consistently moist to waterlogged conditions. Keep the substrate submerged or very wet. Avoid letting the soil dry out at any point, especially during establishment.

Flooding the pot or planting area is ideal for mimicking its natural habitat.

Pruning is generally not required for Sonneratia griffithii unless you need to manage its size or shape. If pruning is necessary, do so lightly in late spring or early summer after flowering.

Remove any dead, damaged, or crossing branches to maintain plant health and structure.

Propagation is primarily done through seeds. Fresh seeds should be sown in brackish, waterlogged soil. Germination can be sporadic.

Cuttings are also possible, taken from semi-hardwood during the growing season and planted in a well-draining, saline medium.

Repot Sonneratia griffithii infrequently, as it prefers to be undisturbed. If repotting is necessary, typically every 2-3 years, do so in spring before new growth begins.

Use a well-draining, saline or brackish substrate and ensure the new pot allows for waterlogged conditions.
