Water regularly, allowing the soil to dry slightly between waterings. In hot, dry conditions, more frequent watering may be necessary. Ensure good drainage to prevent root rot.

Overwatering can be detrimental, so err on the side of caution, especially during cooler months.

Prune back to encourage bushier growth and more blooms. Deadhead spent flowers regularly to prolong the blooming period.

In late autumn, cut back plants significantly to prepare them for winter dormancy or to manage size for overwintering.

Propagate from seeds sown in early spring, or from semi-hardwood cuttings taken in late summer. Seeds germinate best with consistent warmth and light. Cuttings root readily in well-draining potting mix.

Both methods are effective for increasing plant numbers.

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

Ensure the new pot is only slightly larger than the previous one to avoid waterlogged soil.
