Water regularly during the growing season, keeping the soil consistently moist but not waterlogged. Reduce watering in winter, allowing the soil to dry out slightly between waterings.

Ensure good drainage to prevent root rot, especially in containers.

Deadhead spent flowers to encourage further blooming and maintain a tidy appearance. Remove any yellowing or dead foliage as needed.

Light pruning after flowering can help maintain plant shape and prevent excessive self-seeding, if desired.

Propagate by seed, which can be sown directly outdoors in spring or autumn. Alternatively, take stem cuttings in late spring or early summer.

Seeds generally germinate readily, and cuttings root easily in moist, well-draining conditions.

Repot young plants annually in spring as needed, or when root-bound. Choose a pot with ample drainage holes. Use a well-draining potting mix, such as a blend of loam, sand, and compost.

Mature plants may not require frequent repotting.
