Water moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in fall and winter, providing only enough to prevent complete desiccation.

Enneapogon desvauxii prefers well-draining soil and is susceptible to root rot if overwatered.

Pruning is primarily done for aesthetic purposes or to manage size. Cut back dead or damaged foliage in late winter or early spring before new growth emerges.

This encourages a tidier appearance and promotes vigorous new shoots. Remove any spent flower stalks if desired.

Propagation is typically done by seed. Sow seeds in spring, either directly outdoors after the last frost or indoors a few weeks prior.

Scarification or a short period of cold stratification may improve germination rates. Division of established clumps is also possible but less common.

Repotting is generally not necessary for this perennial grass, as it is often grown in the ground or in large, permanent containers.

If grown in a container and it becomes root-bound, repot in early spring into a slightly larger pot with well-draining potting mix. This is a rare event.
