Water Koeleria eriostachya regularly during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter.

Avoid waterlogged conditions, as this can lead to root rot. Ensure good drainage to promote healthy root development.

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

This tidies the plant and encourages fresh, vigorous new growth for the coming season.

Propagate Koeleria eriostachya by dividing established clumps in early spring or autumn. You can also sow seeds in spring, either directly outdoors or in a cold frame.

Division is the most common and reliable method for increasing your stock.

Repotting is generally not necessary for Koeleria eriostachya as it is typically grown in the ground.

If grown in a container, repot every 2-3 years in spring when the plant becomes root-bound, using a well-draining potting mix. This provides fresh nutrients and space for root growth.
