Water moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in late summer and autumn as the plant enters dormancy.

Ensure good drainage to prevent root rot, especially during winter.

Remove spent flower stalks after blooming to prevent seed formation and conserve energy for the plant's next growth cycle. Cut back dead foliage in late autumn once it has yellowed and dried.

No significant structural pruning is typically required.

Propagate Eremurus Aitchisonii by dividing the fleshy roots (rhizomes) in early spring or autumn. Ensure each division has at least one bud. Plant the divisions about 10-15 cm deep in well-draining soil.

Germination from seed is slow and can take several years.

Repotting is generally not required frequently. If necessary, such as for division or to refresh the soil, repot in early spring or autumn. Handle the fleshy roots with care to avoid damage.

Use a well-draining potting mix.
