Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in cooler months.

Deadheading spent flowers can encourage more blooms and prevent self-seeding. Minimal pruning is otherwise needed; remove any dead or damaged stems in early spring.

Easily grown from seeds sown directly outdoors after the last frost. Seeds can also be started indoors a few weeks prior to transplanting.

Not typically repotted as it is an annual. If grown in containers, ensure adequate drainage and repot only if root-bound, usually into a slightly larger pot.
