Water consistently during the growing season, allowing the top 2-3 cm of soil to dry out between waterings.

Reduce watering significantly in fall and winter, providing just enough to prevent the soil from becoming bone dry. Overwatering can lead to root rot.

Pruning is generally not required for Phalaris brachystachys unless specific shaping is desired. Dead or damaged foliage can be removed at any time.

If seed heads are undesirable, they can be cut back after flowering to prevent self-seeding.

Propagation is typically done by seed. Sow seeds in spring, either directly into the garden after the last frost or in pots indoors a few weeks prior. Ensure good drainage and consistent moisture for germination.

Division of established clumps can also be done in spring.

As a grass, Phalaris brachystachys is not typically repotted unless grown in containers. If container-grown and root-bound, repot in spring into a slightly larger container with fresh, well-draining potting mix.

This is usually only necessary every 2-3 years.
