Ammannia auriculata thrives in consistently moist to waterlogged conditions. In aquariums, maintain a high water level, allowing the substrate to remain saturated.

Avoid letting the soil dry out completely, as this can stress the plant. For terrestrial cultivation, water regularly to keep the soil consistently damp.

Pruning is primarily for maintaining shape and encouraging bushier growth. Trim leggy stems just above a leaf node.

For submerged growth, regularly thin out overcrowded areas to improve light penetration and water circulation. Dead or yellowing leaves should be removed promptly.

Ammannia auriculata is easily propagated by stem cuttings. Simply take healthy stem tips, at least 5-10 cm long, and plant them directly into the substrate or float them in water.

Roots will develop quickly from the nodes, leading to new plantlets.

For potted specimens, repot annually or when the plant becomes root-bound. Use a nutrient-rich, water-retentive potting mix. Ensure the new pot offers adequate space for root development.

Terrestrial plants may benefit from being placed in a bog garden or a pot with a water reservoir.
