Keep the soil consistently moist but not waterlogged. Cyperus sesquiflorus thrives in damp conditions, similar to its natural wetland habitat.

Water thoroughly when the top centimeter of soil begins to feel dry to the touch. Reduce watering slightly in winter if growth slows.

Pruning is generally minimal. Remove any dead, yellowed, or damaged leaves and flower stalks as they appear. This helps maintain a tidy appearance and encourages new growth. Cut stems back to the base of the plant.

Propagation is easily done by division of clumps in spring or by sowing seeds. For division, carefully separate the rhizomes into smaller sections, ensuring each has roots and shoots, and replant them.

Seeds can be sown in moist, well-draining compost.

Repot young plants annually in spring. Mature plants can be repotted every 2-3 years or when they become root-bound. Use a good quality, general-purpose potting mix that retains moisture.

Choose a pot slightly larger than the current one.
