Dittrichia graveolens is highly drought-tolerant once established. Water sparingly, allowing the soil to dry out completely between waterings. Overwatering can lead to root rot, especially in poorly draining conditions.

In very hot, dry climates, occasional deep watering might be beneficial during extended dry spells.

Prune Dittrichia graveolens in late autumn or early spring to remove dead or spent flower stalks and to shape the plant. Cutting back encourages denser growth.

Removing spent flowers before they set seed can help prevent unwanted self-seeding, as it can be invasive.

Propagation is typically done by seeds sown in spring, either directly outdoors or started indoors a few weeks prior. It can also be propagated by division of clumps in spring.

Due to its vigorous self-seeding, it often propagates itself readily in suitable conditions.

Repotting is rarely necessary for Dittrichia graveolens, as it prefers to be slightly root-bound and thrives in its natural environment. If growing in a container and it becomes severely root-bound, repot in spring to a slightly larger container with well-draining soil.
