Marsh Pennywort thrives in consistently moist to waterlogged conditions. Keep the soil perpetually damp, mimicking its natural boggy habitat. During warmer months, ensure the surface of the soil remains wet.

In winter, allow the top layer to dry slightly, but never let the plant desiccate completely.

Pruning primarily involves tidying up the plant and encouraging denser growth. Trim back any leggy or overgrown stems to maintain a compact form.

Remove any yellowing or dead leaves promptly to prevent disease and maintain aesthetic appeal. Light pruning can be done as needed.

Marsh Pennywort is easily propagated by division or stem cuttings. In spring or summer, divide established clumps, ensuring each section has roots and shoots.

Alternatively, take cuttings of healthy stems and plant them in moist soil or water; they will root readily.

Repot Marsh Pennywort when it becomes root-bound, typically every one to two years. Use a well-draining potting mix amended with peat or coir. Ensure the new pot is only slightly larger than the current one.

This plant prefers to be slightly crowded, so avoid oversized containers.
