Water consistently when the top 2-3 cm of soil feels dry. Avoid overwatering, as Helichrysum arenarium prefers well-drained conditions and is susceptible to root rot. Reduce watering in winter when the plant is dormant.

Deadhead spent flowers regularly to encourage continuous blooming and prevent self-seeding. Lightly prune in late spring or early summer to maintain a bushy shape and remove any straggly stems.

Hard pruning is best done in early spring before new growth begins.

Propagate from seeds sown indoors in early spring, or directly outdoors after the last frost. Stem cuttings can also be taken in late spring or early summer and rooted in moist, well-draining soil or perlite.

Ensure cuttings are taken from healthy, non-flowering stems.

Repot young plants annually or biennially in the spring to provide fresh soil and more space for root growth. Mature plants can be left in their pots for longer periods.

Use a well-draining potting mix, such as a cactus or succulent blend, to ensure adequate drainage.
