Bothriochloa bladhii prefers moderate watering. Allow the soil to dry out slightly between waterings. In hot, dry periods, increase frequency. Ensure good drainage to prevent waterlogging, which can lead to root rot.

Overwatering should be avoided, especially during cooler months.

Pruning is generally minimal for Bothriochloa bladhii. Remove any dead or damaged foliage as needed to maintain a tidy appearance.

In late winter or early spring, before new growth begins, you can cut back the entire plant to about 5-10 cm above the ground to encourage fresh, vigorous growth.

Bothriochloa bladhii can be propagated by seed or by division of established clumps. Seeds can be sown in spring in a well-drained seed-starting mix.

Divisions are best undertaken in spring as well, carefully separating the root ball into smaller sections, each with healthy roots and shoots.

Repotting is typically only necessary if the plant becomes root-bound in a container. This is infrequent for this species as it's often grown in the ground.

If repotting, choose a slightly larger pot with excellent drainage. Repot in spring, using a well-draining potting mix.
