Water moderately when the top inch of soil feels dry. Anthoxanthum brunonis prefers consistent moisture but dislikes waterlogged conditions. Reduce watering in winter dormancy to prevent root rot.

Ensure good drainage to keep roots healthy and thriving throughout the growing season.

Pruning is generally not required for Anthoxanthum brunonis unless it becomes overgrown or develops dead/damaged foliage.

If needed, trim lightly in early spring before new growth emerges to maintain shape and remove any winter damage. Avoid heavy pruning to maintain its natural form.

Propagation is typically done by division of established clumps in early spring. Carefully separate the rhizomes, ensuring each division has roots and shoots. Replant immediately into well-draining soil.

Alternatively, seeds can be sown in autumn or early spring, but germination can be slow.

Repot Anthoxanthum brunonis every 2-3 years or when it outgrows its container. Use a slightly larger pot with fresh, well-draining potting mix. Spring is the ideal time for repotting, preferably after flowering.

Ensure the new pot has adequate drainage holes.
