Water regularly to keep the soil consistently moist, but avoid waterlogged conditions. Allow the top inch of soil to dry out slightly between waterings, especially during hot weather.

Reduce watering during cooler periods or if the plant is established and self-sufficient.

Pruning is generally not necessary for Cleome viscosa, as it is an annual that completes its life cycle in one season. If desired, you can pinch back the tips of young plants to encourage bushier growth.

Remove spent flowers to promote continuous blooming.

Cleome viscosa is easily grown from seed sown directly in the garden after the last frost. Seeds can also be started indoors a few weeks before the last frost and transplanted out.

It readily self-seeds, often returning year after year.

Repotting is not typically required for Cleome viscosa, as it is usually grown as an annual from seed. If started indoors in pots, transplant seedlings into the garden when they are large enough to handle and the danger of frost has passed.
