Barringtonia racemosa thrives in consistently moist soil. Water regularly, ensuring the substrate does not dry out completely, especially during warmer months and when the plant is establishing.

Reduce watering slightly in cooler periods but maintain adequate hydration. Avoid waterlogging, which can lead to root rot.

Prune Barringtonia racemosa to maintain desired shape and size, and to remove any dead, damaged, or crossing branches. Light pruning can be done at any time, but heavier pruning is best performed after flowering.

This encourages bushier growth and can improve air circulation within the plant.

Propagate Barringtonia racemosa from seeds or semi-hardwood cuttings. Seeds require soaking before sowing and can be slow to germinate.

Cuttings should be taken in spring or summer, treated with rooting hormone, and placed in a well-draining medium in a warm, humid environment. Patience is key for successful propagation.

Repot Barringtonia racemosa every 2-3 years, or when the plant becomes root-bound. Spring is the ideal time to repot, just as new growth begins.

Use a well-draining potting mix, such as a blend of peat, sand, and compost. Ensure the new pot provides adequate space for root development.
