Barringtonia apiculata prefers consistently moist soil. Water regularly, especially during dry periods, to maintain soil humidity. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering slightly during cooler months but never allow the soil to dry out completely.

Prune Barringtonia apiculata to maintain shape and encourage bushier growth. Light pruning can be done at any time to remove dead or damaged branches.

For shaping, prune in late winter or early spring before new growth begins. Avoid heavy pruning.

Propagation is typically done through seeds, which require scarification before sowing. Alternatively, cuttings can be taken from semi-hardwood in summer and treated with rooting hormone.

Ensure cuttings are kept in a warm, humid environment to encourage root development.

Repot Barringtonia apiculata every 2-3 years, or when the plant becomes root-bound. Spring is the ideal time for repotting. Use a well-draining potting mix.

Choose a pot that is slightly larger than the current one to allow for root growth.
