Marsilea batardae thrives in consistently wet conditions. Keep the substrate waterlogged or submerged in shallow water. For submerged growth, maintain a water depth of 5-15 cm.

Avoid letting the soil dry out completely at any stage, as this can stress the plant and hinder its development.

Pruning is generally minimal for Marsilea batardae. Remove any dead, yellowing, or decaying leaves as they appear to maintain aesthetic appeal and prevent rot. This also encourages new growth.

Trim back any overly crowded growth to improve air circulation within the pond or water feature.

Propagation is easily achieved through division of mature rhizomes. Carefully separate sections of the rhizome that have at least one growth point.

Alternatively, it can be propagated by spores, though this method is slower and less common. New plantlets will readily establish in suitable conditions.

Repotting is typically only necessary when the plant outgrows its container or when the substrate needs refreshing. This is best done in spring.

Gently remove the plant, divide any overgrown rhizomes, and replant in fresh aquatic soil or a suitable nutrient-rich substrate. Ensure adequate water coverage after repotting.
