Keep the soil consistently moist but not waterlogged during the growing season. Reduce watering in cooler months, allowing the top inch of soil to dry out between waterings.

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

Pinch back young plants to encourage bushier growth. Deadhead spent flowers regularly to promote continuous blooming and prevent self-seeding.

Remove any yellowing or damaged foliage promptly to maintain plant health and appearance.

Easily propagated from seeds sown indoors in early spring, about 6-8 weeks before the last frost. Seeds require light and warmth to germinate. Transplant seedlings outdoors after the danger of frost has passed.

Cuttings can also be taken in summer.

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