Water thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as this grass prefers well-draining soil and can be susceptible to root rot.

Reduce watering frequency during the dormant winter months, allowing the soil to dry out more between waterings.

Prune back dead or damaged foliage in late winter or early spring before new growth begins. This helps maintain a tidy appearance and encourages vigorous new shoots.

Remove any flower stalks that have gone to seed if self-seeding is undesirable.

Slimspike Windmill Grass can be propagated by division of established clumps in early spring. Alternatively, it can be grown from seed, which can be sown directly outdoors in spring after the last frost, or started indoors a few weeks prior.

As an ornamental grass, Chloris andropogonoides is typically planted in garden beds and does not require regular repotting. If grown in containers, repot every 2-3 years in spring into a slightly larger pot with fresh, well-draining potting mix.
