Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out slightly between waterings. Reduce watering in cooler months to prevent root rot.

Ensure good drainage to avoid soggy conditions.

Prune lightly to shape the plant and encourage bushier growth. Remove dead or spent flower stalks regularly to promote continuous blooming. Pinch back young plants to foster a more compact form.

Heavy pruning is generally not necessary unless the plant becomes leggy.

Propagate from seeds sown indoors in early spring, about 6-8 weeks before the last frost. Alternatively, sow seeds directly outdoors after the danger of frost has passed.

Germination can be erratic; a warm, moist environment aids success. Cuttings can also be taken in summer.

Repot young plants annually or when they become root-bound, typically in spring. Use a well-draining potting mix. For mature plants, repot every 2-3 years or when signs of stress appear.

Choose a pot slightly larger than the current one, ensuring adequate drainage holes.
