Water regularly, especially during dry periods, ensuring the soil dries out slightly between waterings. Avoid waterlogging, which can lead to root rot. In containers, water until it drains from the bottom.

Reduce watering in cooler months when growth slows.

Prune after flowering to encourage bushier growth and a second bloom. Remove spent flowers (deadheading) regularly to promote more blooms and prevent seed formation. Lightly trim leggy stems to maintain a compact shape.

Easily propagated from seed sown directly in the garden after the last frost, or started indoors a few weeks prior. Seeds germinate readily.

Cuttings can also be taken in late spring or early summer and rooted in moist soil or water.

Repot young plants annually in spring as needed, typically when root-bound. Choose a pot that is only slightly larger than the previous one. Use well-draining potting mix.

Mature plants may not require frequent repotting.
