Water regularly during the growing season, especially in dry periods. Allow the soil to dry out slightly between waterings.

Reduce watering in autumn and winter, providing just enough to prevent the soil from becoming completely parched. Overwatering can lead to root rot.

Deadhead spent flowers regularly to encourage more blooms and prevent self-seeding. Cut back the plant in late autumn or early spring to remove dead or damaged stems and to shape the plant.

This also helps maintain a tidy appearance.

Propagate by seeds sown in spring, either indoors or directly outdoors after the last frost. Division of established clumps in spring or autumn is another effective method.

Ensure new plants receive adequate moisture and are protected from extreme conditions.

Established plants are generally best left undisturbed in their preferred location. If repotting is necessary, typically for container-grown specimens, do so in spring before new growth begins.

Use a well-draining potting mix and a pot only slightly larger than the current one.
