Calamagrostis anthoxanthoides prefers consistently moist soil but can tolerate some drought once established. Water deeply when the top few centimeters of soil feel dry, especially during prolonged dry spells.

Avoid waterlogged conditions, which can lead to root rot. Reduce watering in winter.

Cut back dead foliage in late winter or early spring before new growth emerges. This helps maintain a tidy appearance and prevents the buildup of decaying plant matter.

Remove any yellowed or damaged leaves throughout the growing season as needed. Deadheading spent flower stalks can improve aesthetics.

Calamagrostis anthoxanthoides is primarily propagated by division of clumps. In early spring, carefully dig up the plant and divide it into sections, ensuring each section has roots and shoots.

Replant the divisions immediately into well-prepared soil. Seeds can also be sown, but division is more reliable for maintaining parent plant characteristics.

For container-grown plants, repot every 2-3 years in early spring before new growth begins. Choose a pot that is one size larger than the current one. Ensure the new pot has adequate drainage.

Refresh the potting mix with a good quality, well-draining compost to provide nutrients and improve soil structure.
