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

Watering, pruning, propagation, and repotting details from plant data
Water consistently, keeping the soil evenly moist but not waterlogged. Allow the top 2-3 cm of soil to dry out slightly between waterings, especially during warmer months.
Reduce watering frequency in cooler periods to prevent root rot.
Prune to maintain shape and remove spent flower stalks. Deadheading can encourage more blooms and prevent self-seeding if desired.
In late autumn or early spring, trim back any leggy or damaged stems to promote bushier growth.
Propagate from seeds sown in autumn or early spring. Seeds may require a period of cold stratification. Alternatively, take basal cuttings in late spring or early summer and root them in a moist, well-draining medium.
Repot young plants annually in spring, or when root-bound. Mature plants can be repotted every 2-3 years. Use a well-draining potting mix, such as a blend of loam, sand, and compost.
Ensure the new pot has adequate drainage holes.
