To cultivate this plant, you must first choose a site that offers full sun or partial shade. Prepare the planting area by loosening the soil down to a depth of at least 30cm and adding organic matter. Plant the rhizomes about 10-15cm deep and 30-45cm apart. Keep the soil moist until the plant establishes itself
Watering needs
Cyperus capensis (Steud.) Endl. var. polyanthemus Kük. prefers wet conditions and thrives in damp soils. During the growing season, water regularly to keep the soil moist, taking care not to overwater and create waterlogged conditions that may damage or rot the roots. In the dormant period, cut back on watering, but do not let the soil dry out entirely.
Fertilization
Though Cyperus capensis (Steud.) Endl. var. polyanthemus Kük. grows well in soils rich in nutrients, you can boost its performance by feeding it with a general-purpose organic fertilizer.

The seeds should be spread on moist soil in a container or directly in the ground. Germination usually occurs within two to three weeks. The seedlings should be transplanted into their permanent location when they are large enough to handle.
Propagation by division
Cyperus capensis (Steud.) Endl. var. polyanthemus Kük. can also be propagated by division. This is best done in early spring or autumn. The plant should be carefully dug up and the clump separated into smaller sections. Each section should have some roots attached. The divided plants should be replanted immediately in their permanent location.
Propagation by cuttings
Cyperus capensis (Steud.) Endl. var. polyanthemus Kük. can also be propagated by cuttings. This method is not commonly used, but it can be successful. Cuttings should be taken in the spring or summer. The cuttings should be approximately 10cm in length and should be taken from the stem just above a node. Remove the leaves from the bottom half of the cutting and dip the base in rooting hormone powder. The cuttings should be planted in moist soil and kept in a warm, humid environment until roots form.
