Siberian Melicgrass prefers consistently moist soil but can tolerate brief dry spells once established. Water deeply when the top few centimeters of soil feel dry.

Avoid waterlogged conditions, which can lead to root rot, especially in cooler temperatures. Reduce watering during winter dormancy.

Cut back all foliage to the ground in late winter or early spring before new growth emerges. This removes dead or damaged material and encourages vigorous new growth.

Deadheading spent flower stalks in summer can improve appearance and prevent unwanted self-seeding if desired.

Siberian Melicgrass is easily propagated by division of established clumps in early spring. Carefully dig up the plant and separate the root ball into smaller sections, ensuring each section has healthy roots and shoots.

Replant immediately into prepared soil.

Repotting is generally not necessary for this perennial grass as it is typically grown in the ground. If grown in a container, repot every 2-3 years in early spring into a slightly larger pot with fresh potting mix to prevent it from becoming root-bound.
