Bulb Arrowgrass prefers consistently moist soil, mimicking its natural wetland habitat. Water regularly, especially during drier periods, to prevent the soil from drying out.

Avoid waterlogged conditions for extended periods, as this can lead to root rot. Ensure good drainage if grown in a container.

Pruning is minimal for Bulb Arrowgrass. Remove any dead, damaged, or yellowing leaves as they appear to maintain the plant's appearance and health. This can be done at any time of year.

Avoid severe pruning, as it focuses on foliage rather than significant structural changes.

Propagation is best achieved through division of established clumps, typically in early spring before new growth begins. Carefully separate the rhizomes, ensuring each division has roots and at least one growth point.

Replant immediately into suitable moist soil. Seed propagation is also possible but less common.

Repot Bulb Arrowgrass when it becomes root-bound, usually every 2-3 years. This is best done in early spring. Choose a pot that is slightly larger than the current one, ensuring adequate drainage.

Use a well-draining, moist potting mix, ideally with some organic matter.
