Water moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter, providing just enough to prevent the soil from becoming bone dry.

Ensure good drainage to avoid root rot, especially in containers.

Prune back dead or damaged foliage as needed to maintain a tidy appearance. In late winter or early spring before new growth emerges, you can cut back the entire plant by about one-third to encourage vigorous new shoots and prevent it from becoming too leggy or unkempt.

Propagate Eragrostis multicaulis by division of established clumps in spring. Gently separate sections of the root ball, ensuring each division has roots and shoots. Replant immediately into well-draining soil.

It can also be grown from seed sown in spring under glass.

Repot Eragrostis multicaulis every 2-3 years or when it becomes root-bound. Choose a pot that is only slightly larger than the current one and ensure it has drainage holes.

Use a well-draining potting mix, such as a standard compost mixed with grit or perlite.
