Water: Roundfruit rush thrives in moist environments, requiring consistent hydration and weekly watering. It is moderately drought-tolerant and prefers outdoor cultivation to utilize natural rainfall. Efficient irrigation practices are essential for its growth cycle, which is closely linked to water availability.

Fertilize: For optimal nourishment of roundfruit rush, apply a thin layer of mulch or compost annually in spring. This enriches the soil, enhancing growth and resilience. Adjust quantity during active growth to prevent root burn, and ensure even distribution for novice gardeners while experienced ones may customize based on soil tests.

Pruning: Roundfruit rush has tough, grass-like leaves and compact fruit capsules. Pruning in early spring encourages new growth and maintains tidiness. It helps prevent overcrowding, promotes air circulation, and reduces disease risk. Use sharp, clean tools for effective pruning and healthy regrowth.

Propagation: Roundfruit rush is a resilient perennial, easily propagated by dividing clumps. Ensure roots remain intact during separation and replant promptly in moist soil at original depth. Maintain thorough watering and adhere to its native habitat care for optimal growth.
