Avicennia officinalis thrives in consistently moist, saline conditions. Mimic its natural habitat by keeping the soil perpetually wet, but avoid waterlogging.

For indoor cultivation, a shallow water tray can be beneficial. Regular watering is crucial, especially during warmer periods, to maintain soil saturation.

Pruning is generally minimal for Avicennia officinalis. If necessary, prune to maintain shape or remove dead or damaged branches. Avoid heavy pruning as it can stress the plant.

Lightly trim new growth to encourage bushier development. Pruning is best done in spring or early summer.

Propagation is typically done via seeds. Sow fresh seeds immediately in saline, waterlogged soil. Germination is usually rapid.

For more advanced propagation, cuttings can be taken from mature stems, but success rates can be variable. Ensure high humidity and warmth for best results.

Repotting is infrequent, as mangroves prefer to be slightly root-bound. Only repot when the plant outgrows its container, typically every 2-3 years. Use a well-draining, saline-tolerant potting mix.

Handle the roots gently, as they are sensitive. Repot in spring.
