Southern Cut Grass thrives in consistently moist to wet conditions. Water frequently, ensuring the soil remains saturated, especially during warmer months.

Avoid allowing the soil to dry out completely, as this can stress the plant. In natural settings, it often grows in shallow water or waterlogged soil.

Pruning is generally minimal for Southern Cut Grass. Remove any dead or discolored foliage as needed to maintain a tidy appearance.

In ornamental settings, you can cut back the entire plant in late winter or early spring before new growth emerges to encourage fresh, lush foliage.

Southern Cut Grass is easily propagated by division of established clumps in spring.

Simply dig up the plant, separate the rhizomatous roots into smaller sections, each with some viable roots and shoots, and replant them. It can also be propagated from seed sown in moist soil.

Repotting is rarely necessary for Southern Cut Grass unless it is grown in a container and has become root-bound. If container-grown, repot in spring into a slightly larger container with fresh, moist potting mix.

Ensure the new pot allows for consistent moisture retention.
