Avicennia marina thrives in consistently moist, even waterlogged conditions, mimicking its natural estuarine habitat. Regular watering is essential, especially during warmer periods.

Ensure the substrate remains saturated, but avoid prolonged stagnant water unless in a hydroponic setup. Reduce watering slightly in cooler months to prevent root rot.

Pruning is primarily for shape and size management, or to remove dead or crossing branches. Light pruning can be done year-round. For more significant shaping, prune in late spring or early summer.

Avoid heavy pruning, as this can stress the plant. Clean cuts will promote faster healing.

Seed propagation is common. Freshly collected propagules (viviparous seeds) should be sown immediately in moist, saline substrate. Germination is usually rapid.

Cuttings are less common but can be taken from mature stems and rooted in saline conditions. This method requires patience and specific environmental controls.

Avicennia marina has a tolerance for being root-bound, typical of many mangrove species. Repotting is infrequent, perhaps every 2-3 years, or when the plant significantly outgrows its container.

Use a well-draining, sandy, slightly saline substrate. Perform repotting in spring to allow for recovery during the growing season.
