Keep the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out slightly between waterings.

Reduce watering frequency during cooler months to prevent root rot, ensuring adequate drainage to avoid standing water.

Deadhead spent flowers regularly to encourage continuous blooming throughout the season. In late autumn or early spring, trim back any leggy or overgrown stems to maintain a compact and tidy shape.

Remove any dead or diseased foliage promptly.

Propagate from basal cuttings taken in spring. Select healthy shoots and root them in a well-draining potting mix.

Alternatively, sow seeds in spring under glass, transplanting seedlings when large enough to handle into their final positions.

Repot every two to three years in spring, or when the plant becomes root-bound. Use a slightly larger pot with fresh, well-draining compost.

Gently loosen the roots before placing the plant in its new container, ensuring it is at the same depth as before.
