Water moderately, ensuring good drainage. Avoid waterlogged conditions, especially during winter.

Deadheading spent flowers can encourage further blooming and prevent self-seeding if unwanted. Minimal pruning is otherwise required.

Easily grown from seed sown directly outdoors in early spring or autumn. Can also be started indoors a few weeks before the last frost.

Not typically repotted as it is an annual. If grown in pots, ensure adequate space and repot into a larger container if root-bound before planting out.
