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

Ensure good drainage to avoid waterlogging, which can lead to root rot.

Prune back old foliage in late winter or early spring before new growth emerges. This removes dead or damaged material and encourages vigorous new growth.

Cut stems to a few centimeters above the ground to maintain a tidy appearance and promote dense flowering.

Propagate primarily through division of established clumps in spring. Carefully separate sections of the root system, ensuring each piece has at least a few healthy shoots and roots.

Replant immediately in well-draining soil and water lightly.

Repotting is generally not required frequently for Chrysopogon benthamianus as it prefers to be slightly pot-bound. If repotting becomes necessary due to overcrowding or poor drainage, do so in spring, using a gritty, well-draining potting mix.
