Water Festuca glauca thoroughly when the top 2-3 cm of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot.

Drought tolerant once established, but occasional deep watering during prolonged dry spells will ensure optimal health and appearance.

Prune Festuca glauca in late winter or early spring before new growth emerges. Cut back the entire plant to about 5-10 cm above the ground to remove dead or faded foliage.

This encourages fresh, vibrant blue growth and maintains a tidy appearance.

Propagate Festuca glauca by division in early spring or autumn. 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-draining soil.

Repotting is generally not required for Festuca glauca as it is often grown as an accent plant in garden beds or containers. If grown in a container and it becomes root-bound, repot in spring to a slightly larger container with fresh, well-draining potting mix.
