Water Nassella hyalina moderately during its active growing season (spring and summer), allowing the soil to dry slightly between waterings. Reduce watering significantly in fall and winter to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, which this grass dislikes.

Prune Nassella hyalina in late winter or early spring before new growth begins. Cut back the dead foliage to about 5-10 cm above the ground.

This removes old growth, stimulates fresh shoots, and maintains a tidy appearance. Wear gloves as the foliage can be sharp.

Nassella hyalina is primarily propagated by seed. Sow seeds in spring or fall in well-draining soil. Alternatively, divide established clumps in early spring.

Ensure divisions have roots and a few shoots before replanting. This grass can also self-seed readily.

Repotting is generally not necessary for Nassella hyalina when grown in the ground. For container-grown plants, repot every 2-3 years in spring if the plant becomes root-bound.

Use a well-draining potting mix and a slightly larger pot to accommodate its root system.
