Water Chestnut thrives in consistently moist to submerged conditions. It requires a shallow layer of water covering its substrate, mimicking its natural wetland habitat.

Maintain water levels to prevent the soil from drying out, especially during active growth. Avoid stagnant water for extended periods to prevent root rot.

Pruning is generally not required for Water Chestnut unless stems become overly long or damaged. Remove any yellowing or decaying leaves promptly to maintain plant health and appearance.

Avoid heavy pruning, as it can stress the plant. Focus on removing dead or diseased material.

Propagation is primarily achieved through division of the corms. In spring, before new growth begins, carefully separate the corms. Each corm should have at least one bud to ensure successful propagation.

Plant the separated corms in shallow water or moist soil.

Repotting is typically only necessary if the plant outgrows its container or if the substrate needs refreshing. This is best done in early spring. Use a well-draining aquatic soil mix.

Ensure the new container allows ample space for root development and is stable in water.
