Fertilize: For flat sedge, enrich soil with organic mulch or compost annually during spring-summer for nutrient replenishment and robust growth. Use a balanced, slow-release fertilizer, avoiding over-fertilization. As seasons change, reduce applications to support flat sedge's dormancy. Wear gloves and distribute evenly to enhance health and stress resilience.

Pruning: Flat sedge is a grass-like plant characterized by compressed stems and dense growth. Prune in early spring to remove dead foliage and promote new shoots. Maintaining moderate height aids air circulation, reduces disease risk, and improves appearance and vigor for sustainable growth throughout the season.

Propagation: Flat sedge is best propagated through careful division, ensuring each section retains adequate root structure. Replant segments promptly in moist, well-draining soil for optimal results, particularly during the plant's vigorous growth phase to support quick establishment and recovery.
