Fragrant Flatsedge thrives in consistently moist to wet conditions. Water regularly, allowing the soil to dry out slightly between waterings. In bog gardens or ponds, ensure the base is submerged.

Overwatering is generally not an issue for this moisture-loving plant.

Pruning is minimal and mainly involves removing dead or damaged foliage. Cut back stems at the base as needed to maintain a tidy appearance.

This can be done anytime during the growing season, or more extensively in late winter before new growth emerges.

Fragrant Flatsedge is easily propagated by division of clumps in spring. Simply dig up the plant, separate the rhizomatous root system into smaller sections, and replant.

Seeds can also be sown in moist soil in spring or autumn.

Repotting is typically only necessary when the plant becomes root-bound, usually every 2-3 years. If grown in a container, choose a pot that is slightly larger.

Repot in spring, ensuring the new pot provides adequate drainage and space for root growth.
