Water moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter when the plant is dormant.

Ensure good drainage to prevent waterlogging, as Oriental Junegrass is drought-tolerant once established.

Prune in late winter or early spring before new growth begins. Cut back dead or damaged foliage to about 5-10 cm above the ground. This encourages vigorous new growth and maintains a tidy appearance.

Remove any invasive shoots to control spread.

Propagate primarily through division of clumps in early spring. Carefully dig up the plant and separate it into smaller sections, each with roots and shoots. Replant divisions immediately into well-draining soil.

Seeds can also be sown in autumn or early spring.

Repotting is generally not necessary for ornamental grasses like Oriental Junegrass, as they prefer to be slightly pot-bound.

If division is done in containers, repot into a slightly larger pot with fresh, well-draining soil mix. This is typically done every 2-3 years.
