Water regularly during the growing season, allowing the soil to dry out slightly between waterings. Prairie Sunflowers are drought-tolerant once established. Reduce watering in the fall as the plant begins to senesce.

Ensure good drainage to prevent root rot.

Pruning is usually not necessary for Prairie Sunflowers. Deadheading spent blooms can prevent self-seeding if unwanted volunteers are a concern.

If the plant becomes leggy or overgrown, you can cut it back in late spring to encourage bushier growth.

Prairie Sunflowers are easily propagated by seeds, which can be sown directly outdoors in the spring after the last frost. They can also be started indoors a few weeks before the last frost. Seedlings transplant well.

Repotting is not typically required for Prairie Sunflowers as they are often grown as annuals or in the ground. If growing in containers and the plant becomes root-bound, repot into a slightly larger container in the spring before new growth begins.
