Water moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in autumn and winter, especially if grown in cooler conditions, to prevent root rot.

Ensure good drainage to avoid waterlogged conditions.

Prune lightly after flowering to maintain a tidy shape and encourage further blooming. Deadhead spent flowers regularly.

In late autumn or early spring, you can cut back any leggy or straggly growth to promote denser, bushier plant habit.

Easily propagated from seed sown in spring or autumn, either indoors or directly outdoors in a prepared seedbed. Cuttings can also be taken from semi-ripe shoots in summer and rooted in a moist, well-draining medium.

Repot annually in spring if the plant becomes root-bound, using a well-draining potting mix. Choose a pot that is only slightly larger than the previous one.

Ensure the pot has adequate drainage holes to prevent water accumulation around the roots.
