Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in fall and winter, especially if grown in cooler conditions.

Ensure good drainage to prevent root rot, as this plant prefers drier conditions once established.

Prune back spent flower stalks to encourage reblooming and maintain a tidy appearance. In late winter or early spring, before new growth begins, cut back the plant by about one-third to one-half to promote dense, bushy growth and prevent woodiness.

Easily propagated from seeds sown in spring, either indoors or directly outdoors after the last frost. Division of established clumps in spring or fall is also an effective method.

Cuttings taken in late spring or early summer can also be rooted.

Repot container-grown plants every 2-3 years, or when they become root-bound. Spring is the ideal time to repot, using a well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
