Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, especially during winter dormancy. Allow the soil to dry out slightly between waterings to prevent root rot.

Reduce watering significantly in cooler months.

Prune back stems by about one-third in early spring to encourage bushier growth and abundant flowering. Deadhead spent blooms throughout the growing season to prolong blooming and maintain an attractive appearance.

Remove any winter-damaged stems.

Easily propagated from seed sown in spring or by taking basal cuttings in late spring or early summer. Seeds can be sown directly into the garden after the last frost or started indoors a few weeks prior.

Cuttings root readily in moist, well-draining soil.

Repot established plants every 2-3 years in early spring, or when root-bound, into a slightly larger container with fresh, well-draining potting mix. Ensure the new pot has adequate drainage holes.

Avoid over-potting, which can lead to excess moisture retention.
