Water
Water regularly, especially during establishment, but allow the soil to dry slightly between waterings. Once established, it tolerates drought well. Overwatering can lead to root rot, so ensure good drainage.
Reduce watering in winter.

Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during establishment, but allow the soil to dry slightly between waterings. Once established, it tolerates drought well. Overwatering can lead to root rot, so ensure good drainage.
Reduce watering in winter.
Prune after flowering to remove spent flower stalks, which encourages reblooming and maintains a tidy appearance. Deadhead regularly throughout the season.
Heavy pruning can be done in late winter or early spring before new growth begins to shape the plant.
Propagate from seed sown in early spring, either indoors or directly outdoors after the last frost. Stratification may improve germination rates.
Cuttings can also be taken from semi-hardwood in summer, though this method is less common and can be more challenging.
Repot only when necessary, typically every 2-3 years, as Limonium californicum prefers to be slightly root-bound. Choose a pot with excellent drainage. Repot in spring before new growth begins.
Handle the roots gently to minimize disturbance.
