Water thoroughly when the soil is dry, typically every 2-4 weeks during the growing season. Reduce watering significantly in winter, allowing the soil to dry out completely between waterings to prevent root rot.

Ensure excellent drainage.

Remove dead or damaged leaves at the base of the plant using clean, sharp tools. Pruning is generally minimal for Dasylirion serratifolium, as it naturally forms an attractive rosette. Avoid cutting healthy foliage.

Propagate from seeds sown in spring, requiring warm temperatures and well-draining soil. Germination can be slow and erratic. Division of offsets is rarely feasible due to the plant's growth habit.

Repot only when the plant is severely root-bound, typically every 3-5 years. Use a gritty, well-draining potting mix. Repot in spring before active growth begins, handling the roots with care to avoid damage.
