Bromus cebadilla prefers consistently moist soil during its active growing season, typically spring and autumn. Reduce watering significantly during hot, dry summer months and overwintering.

Allow the top few centimeters of soil to dry out between waterings to prevent root rot. Avoid waterlogged conditions.

Pruning is minimal. Remove any dead or yellowing foliage as it appears to maintain a tidy appearance.

In late autumn or early winter, consider cutting the entire plant back to a few centimeters above the ground to encourage fresh growth in the spring.

Bromus cebadilla is primarily propagated by seed. Sow seeds in early spring or autumn in a well-draining seed-starting mix. Germination typically occurs within 2-4 weeks.

Division of established clumps in spring is also an effective method for propagation.

Repotting is generally not necessary for this grass unless it is grown in a container. If container-grown, repot in spring every 2-3 years into a slightly larger pot with fresh, well-draining potting mix.

Ensure good drainage in the pot.
