Water moderately, allowing the soil to dry slightly between waterings. Avoid waterlogging, as this can lead to root rot. In hot, dry weather, more frequent watering may be necessary to maintain consistent soil moisture.

Reduce watering during cooler periods and dormancy.

Pruning is generally minimal. Lightly trim back leggy stems to encourage bushier growth and more flowering. Remove any dead or damaged branches as needed.

Pruning can also be done after flowering to tidy up the plant's appearance.

Easily propagated from seeds sown directly into the garden after the last frost or started indoors a few weeks prior. Seeds can also be scarified or soaked briefly to improve germination rates.

Cuttings can be taken from healthy stems.

This plant is not typically repotted frequently as it is often grown as an annual or in its natural habitat. If grown in a container and it becomes root-bound, repot into a slightly larger container with fresh, well-draining potting mix in the spring.
