Allow the soil to dry out completely between waterings. Oloptum miliaceum is drought-tolerant once established. Overwatering can lead to root rot, so err on the side of underwatering, especially in cooler months.

Reduce watering significantly in winter.

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

Cut the grass down to a few centimeters above the ground to promote healthy regeneration.

Propagation is typically done by division of established clumps in early spring. Carefully separate the rhizomatous root system into smaller sections, ensuring each piece has a few shoots and roots.

Replant immediately into well-draining soil.

Repotting is rarely necessary for Oloptum miliaceum as it is usually grown in garden settings. If grown in a container, it may benefit from repotting every 2-3 years to refresh the soil and provide more space, ideally in spring.
