Hordeum bogdanii prefers consistently moist soil during its active growth period but can tolerate drier conditions once established. Water deeply when the top 2-3 cm of soil feels dry.

Reduce watering in fall and winter to prevent waterlogged conditions, especially if overwintering outdoors.

Pruning is typically not necessary for Hordeum bogdanii beyond removing dead or damaged foliage. In late winter or early spring, before new growth begins, cut back any browned or tattered leaves from the previous season to maintain a tidy appearance and encourage fresh emergence.

Hordeum bogdanii can be propagated by division or seed. Divisions are best undertaken in spring as growth begins. Sow seeds in early spring or fall.

Seeds may require a period of cold stratification to improve germination rates. Ensure good drainage for both methods.

Repotting is generally not required for Hordeum bogdanii as it is a perennial grass often grown in the ground or in large containers where it can establish. If grown in a container and it becomes root-bound, repot in spring into a slightly larger container with fresh, well-draining potting mix.
