Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogging, as this can lead to root rot. Allow the top few centimeters of soil to dry out between waterings for mature plants.

Pruning is typically minimal. Remove any dead, damaged, or diseased stems as needed. To prevent excessive self-seeding, deadhead spent flowers before they develop into seed pods.

Light trimming can help maintain a neater appearance.

Descurainia sophia is easily propagated by seed. Sow seeds directly into the garden in early spring or in the fall. They can also be started indoors a few weeks before the last frost.

Division of established clumps is possible but less common.

As an annual or short-lived perennial, repotting is generally not necessary. If grown in containers, it may be beneficial to repot every year or two in fresh potting mix to ensure good drainage and aeration, especially if the plant appears root-bound.
