Water Pseudognaphalium sandwicensium moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in cooler months or when the plant is dormant.

Ensure good drainage to prevent root rot, as it prefers drier conditions.

Prune Pseudognaphalium sandwicensium after flowering to maintain shape and encourage bushier growth. Remove spent flower stalks to prevent self-seeding if desired.

Light annual pruning is usually sufficient to keep it tidy.

Propagate Ena'ena from seeds sown in spring or by stem cuttings taken in late spring or early summer. Seeds germinate best with light stratification. Cuttings root readily in moist, well-draining medium.

Repot Pseudognaphalium sandwicensium when it becomes root-bound, typically every 2-3 years. Use a well-draining potting mix, such as a cactus or succulent blend, and a pot with drainage holes.

Repot in spring before active growth begins.
