Koeleria glauca prefers well-drained soil and can tolerate some drought once established. Water moderately during active growth in spring and summer, allowing the soil to dry out slightly between waterings.

Reduce watering significantly in autumn and winter to prevent root rot. Overwatering is detrimental.

Prune Koeleria glauca in late winter or early spring before new growth emerges. Cut back the old, dead foliage to about 5-10 cm above the ground.

This tidies the plant, encourages fresh growth, and prevents the accumulation of old, decaying material, which can harbor pests or diseases.

Koeleria glauca is best propagated by division in early spring. Carefully dig up the plant and divide the root ball into smaller sections, ensuring each section has roots and shoots.

Replant the divisions immediately into well-drained soil. Alternatively, it can be propagated from seed sown in autumn or early spring.

Repotting is generally not necessary for Koeleria glauca as it is a perennial grass often grown in garden beds. If grown in containers, repot every 2-3 years in early spring when the plant becomes root-bound.

Use a well-draining potting mix and a slightly larger container to accommodate its growth.
