Ammannia cordata prefers consistently moist soil, mimicking its native wetland environment. Avoid allowing the substrate to completely dry out between waterings, especially during active growth.

In aquatic setups, ensure the water level is maintained to keep the roots submerged. Reduce watering slightly in cooler months.

Pruning Ammannia cordata is primarily for shaping and encouraging bushier growth. Trim back leggy stems just above a leaf node to stimulate branching.

Regular pinching of the tops can help maintain a more compact form and prevent the plant from becoming too tall or sparse.

Ammannia cordata is easily propagated through stem cuttings. Take cuttings of 5-10 cm from healthy stems and plant them directly into moist substrate or float them in water.

Roots will form relatively quickly, allowing for new plants to be established.

Ammannia cordata benefits from repotting when it becomes root-bound or outgrows its container. This is typically done every 1-2 years, ideally in spring.

Use a well-draining potting mix, potentially with added sand or gravel for better aeration, and ensure the new pot offers adequate space.
