Water regularly during the growing season, especially in dry periods, to maintain consistently moist soil. Allow the soil surface to dry slightly between waterings. Reduce watering in autumn and winter.

Ensure good drainage to prevent waterlogging, which can lead to root rot.

Cut back dead foliage in late winter or early spring before new growth emerges. This tidies the plant and encourages fresh growth. Remove any damaged or diseased leaves throughout the year.

Established clumps can be divided, which also serves as a form of rejuvenation.

Propagate by division in early spring. Carefully dig up the clump and divide it into smaller sections, ensuring each section has healthy roots and shoots. Replant divisions immediately into well-prepared soil.

It can also be grown from seed, sown in autumn or spring.

Molinia arundinacea is a perennial grass that is not typically grown in containers for long periods. If grown in a pot, repot every 2-3 years in spring when the plant becomes root-bound.

Use a larger pot with fresh, well-draining potting mix. Ensure adequate drainage holes.
