Arum hygrophilum prefers consistently moist soil, mimicking its natural wetland habitat. Water thoroughly when the top few centimeters of soil begin to feel dry.

Avoid waterlogging, but do not allow the soil to dry out completely. Reduce watering slightly during the dormant period.

Prune away any yellowed or dead foliage as it appears to maintain plant health and appearance. After flowering and seed set, the leaves will naturally die back.

Cut back the dead stems and foliage to the ground level in late autumn or early winter.

Propagation is typically done by dividing the rhizomes in early spring before new growth begins. Carefully separate the rhizomes, ensuring each piece has at least one bud.

Replant them in moist, well-draining soil at the appropriate depth.

Repot Arum hygrophilum every 2-3 years, or when the rhizomes have filled the pot. This is best done in early spring before active growth commences.

Use a larger pot with fresh, well-draining potting mix enriched with compost.
