Water consistently, especially during establishment and dry periods, but avoid waterlogging. Allow the top few centimeters of soil to dry out between waterings.

Reduce watering in cooler months when the plant is less active. Good drainage is crucial to prevent root rot.

Pruning is typically minimal for Bunias erucago. Remove any dead, damaged, or diseased stems as needed.

Occasional light trimming can help maintain a tidy appearance and encourage bushier growth, especially if it becomes leggy. Deadheading spent flowers can prevent unwanted self-seeding.

Bunias erucago is easily propagated by seeds sown directly outdoors in early spring or autumn. It can also be propagated by division of established clumps in spring.

Some sources indicate stem cuttings may be successful, though less common.

Repotting is rarely necessary for Bunias erucago, as it is often grown as an annual or short-lived perennial and prefers a permanent location.

If container-grown, repot only when severely root-bound, typically in spring, using a well-draining potting mix. Ensure the new pot is only slightly larger.
