Water thoroughly when the top 2-3 cm of soil feels dry. Grindelia species are drought-tolerant and prefer to dry out between waterings.

Avoid overwatering, as this can lead to root rot, especially in poorly draining soils.

Prune after flowering to maintain a tidy appearance and encourage bushier growth. Deadhead spent blooms to prevent self-seeding if unwanted.

Light pruning can also be done in early spring to remove any winter damage and shape the plant.

Propagate from seed sown in spring or early summer, either indoors or directly outdoors after the last frost. Cuttings can also be taken in late spring or early summer. Ensure good drainage for both methods.

Repot only when necessary, typically when the plant becomes root-bound, usually every 2-3 years. Use a well-draining potting mix, such as a cactus or succulent blend. Repot in spring before new growth begins.
