Water Panicum capillare regularly, especially during establishment and dry periods. Allow the soil to dry out slightly between waterings.

While drought-tolerant once established, consistent moisture promotes better growth and flowering. Avoid waterlogged conditions, which can lead to root rot.

Prune Panicum capillare in late winter or early spring before new growth emerges. Cut back all old flowering stalks and foliage to about 5-10 cm above the ground.

This tidies the plant and encourages vigorous new growth, preventing it from looking straggly.

Propagate Panicum capillare by seed or division. Sow seeds in early spring, either directly outdoors or indoors a few weeks prior. Divisions can be made in spring or fall.

Gently separate clumps, ensuring each piece has roots and shoots, and replant them promptly.

Repotting is generally not necessary for Panicum capillare as it is a perennial grass often grown in the ground.

If grown in a container, repot every 2-3 years in early spring to refresh the soil and accommodate root growth. Use a well-draining potting mix.
