Cyperus vandervekenii thrives in consistently moist soil. Water frequently, ensuring the potting mix never dries out completely. Aim to keep the substrate wet, especially during active growth periods.

Reduce watering slightly in cooler months, but still maintain adequate moisture to prevent the plant from wilting.

Pruning is minimal for Cyperus vandervekenii. Remove any yellowed or dead leaves and flower stalks as they appear to maintain a tidy appearance and encourage new growth.

This can be done with clean scissors or pruning shears at any time of year.

Propagate Cyperus vandervekenii by division of the root ball in spring. Carefully separate mature clumps into smaller sections, ensuring each piece has roots and shoots. Replant them in moist potting mix.

Alternatively, seeds can be sown in a moist medium, but division is generally easier.

Repot Cyperus vandervekenii every 1-2 years, or when it becomes root-bound. Spring is the ideal time for repotting.

Choose a pot that is slightly larger than the current one and use a well-draining, peat-based potting mix. Ensure the new pot has drainage holes.
