Oenanthe benghalensis thrives in consistently moist to wet conditions. Water regularly to keep the soil saturated, especially during warmer months. Avoid letting the soil dry out completely.

In its natural aquatic habitat, it receives ample water, so mimic this by placing pots in shallow water or saucers filled with water.

Pruning is mainly for maintaining shape and removing dead or yellowing foliage. Trim back stems as needed to prevent the plant from becoming leggy or overcrowded.

This can be done at any time, but is most effective in spring before vigorous growth begins. Remove any spent flower stalks to encourage further blooming.

Propagation is typically done through division of established clumps in spring or by taking stem cuttings. Cuttings can be rooted in water or moist potting mix.

For division, carefully separate the rhizomes or root systems, ensuring each piece has some healthy shoots and roots, and replant immediately into moist soil.

Repot Oenanthe benghalensis when it becomes root-bound, usually every 1-2 years. This is best done in early spring before new growth starts. Use a well-draining potting mix amended with organic matter.

If planting in a pond, ensure the pot is stable and sunk into the substrate.
