Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top centimeter of soil to dry out slightly between waterings. Reduce watering during winter months to prevent root rot.

Ensure good drainage to avoid issues.

Prune back established plants in late winter or early spring to encourage bushy growth and prevent legginess.

Deadhead spent flowers throughout the growing season to promote continuous blooming and maintain a tidy appearance. Remove any diseased or damaged foliage promptly.

Propagate by division of clumps in spring or by softwood cuttings taken in late spring or early summer. Seeds can also be sown in spring, either indoors or directly outdoors after the last frost.

Ensure good air circulation for cuttings.

Repot young plants annually or as needed when they become root-bound, usually in spring. Mature plants can be repotted every 2-3 years. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one.
