Water sparingly, allowing the soil to dry out completely between waterings. Nolina arenicola is drought-tolerant and susceptible to root rot if overwatered, especially in cooler temperatures.

Reduce watering significantly during winter months to mimic its natural arid conditions.

Pruning is rarely required. Remove any dead or damaged leaves by cutting them back to the base of the plant.

If the trunk develops an undesirable shape, it can be pruned, but this will not induce branching and should be done cautiously.

Propagation is typically done by seed, which requires patience as germination can be slow and erratic. Seeds should be sown in a well-draining, gritty mix and kept warm.

Vegetative propagation is not common or easily achieved for this species.

Repot only when absolutely necessary, typically every 3-5 years or when the plant becomes root-bound. Use a very gritty, well-draining potting mix. Choose a pot only slightly larger than the current one.

Repotting is best done in spring.
