Water Fall Witchgrass regularly during its establishment phase, especially in its first year. Once established, it becomes quite drought tolerant.

Allow the soil to dry out somewhat between waterings, but avoid prolonged periods of dryness. Overwatering can lead to root rot.

Prune Fall Witchgrass in late winter or early spring before new growth begins. Remove any dead or damaged foliage and spent flower stalks from the previous season.

This promotes a tidy appearance and encourages vigorous new growth.

Fall Witchgrass is easily propagated by division of established clumps in early spring or fall. It can also be grown from seed, sown directly into the garden in fall or early spring, or started indoors a few weeks before the last frost.

Repotting is typically not necessary for Fall Witchgrass as it is usually grown in the ground. If grown in a container, repot in early spring every 2-3 years when the plant becomes root-bound, using a well-draining potting mix.
