Foxtail barley is drought-tolerant once established. Water moderately during dry spells, especially when young. Aim to keep the soil consistently moist but not waterlogged.

Reduce watering in cooler months when growth slows. Overwatering can lead to root rot.

Pruning is primarily for aesthetic appeal and seed head management. Remove spent flower stalks after blooming to prevent unwanted reseeding and to maintain a tidy appearance.

Cut back dead foliage in late winter or early spring before new growth emerges.

Foxtail barley is easily propagated by seed. Sow seeds directly outdoors in autumn or early spring.

It can also be propagated by division of established clumps in spring, which is a reliable method to ensure desired characteristics.

Repotting is generally not applicable for this species as it is an outdoor ornamental grass typically grown in the ground. If grown in containers for temporary display, repotting would be done in spring when the plant is actively growing, moving it to a slightly larger pot.
