Hydrocharis chevalieri thrives in consistently moist to submerged conditions. Ensure the substrate remains waterlogged or the plant is fully aquatic.

Regularly top up water levels in containers or ponds to prevent drying out, especially during warmer months. Avoid letting the roots dry out completely, as this can be detrimental.

Pruning is generally not required for Hydrocharis chevalieri unless it becomes overly dense and begins to crowd out other aquatic species.

If necessary, simply remove excess foliage or runners by hand to maintain desired coverage. This can be done throughout the growing season as needed to manage its spread.

Hydrocharis chevalieri propagates readily through runners and plantlets. During the growing season, it produces stolons that develop into new individuals.

These can be detached and allowed to float freely in the water or gently anchored in substrate to establish new plants. Division of larger clumps is also an effective method.

Repotting is typically not necessary for Hydrocharis chevalieri as it is an aquatic or semi-aquatic plant that often disperses freely. If grown in a contained environment and it outgrows its space, or if the substrate needs refreshing, gently replant divisions into a suitable aquatic soil mix in a larger container or directly into the pond.
