Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top centimeter of soil to dry out between waterings. Reduce watering in cooler months when the plant is dormant.

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

Pinch back young plants to encourage bushier growth. Remove spent flowers (deadheading) to promote continuous blooming and prevent self-seeding if unwanted. Prune lightly after flowering to maintain shape and tidiness.

Propagate from seed sown directly outdoors in early spring or autumn. Seeds germinate best with light stratification. Can also be propagated by cuttings taken in late spring or early summer.

Seeds are the most common and reliable method.

Repot young plants annually or as needed when root-bound, typically in spring. Use a well-draining potting mix. Choose a pot only slightly larger than the current one. Ensure the new pot has adequate drainage holes.
