Rough Dog's-Tail prefers well-drained soil and is drought-tolerant once established. Water moderately during dry periods, especially in the first year. Avoid waterlogged conditions, as this can lead to root rot.

Allow the soil to dry out slightly between waterings for optimal health.

Pruning is minimal for Rough Dog's-Tail. Remove any dead or damaged foliage as needed, typically in late winter or early spring before new growth emerges.

This helps maintain a tidy appearance and encourages vigorous new shoots.

Propagation is primarily done through seed. Sow seeds in autumn or early spring in well-drained soil. Germination typically occurs within 1-3 weeks.

Alternatively, division of established clumps can be done in spring, though this is less common for this species.

Repotting is generally not applicable to Rough Dog's-Tail as it is a perennial grass often grown directly in the ground or in large containers. If grown in a container, ensure it is large enough to accommodate root growth, and repot only if root-bound, which is infrequent.
