Water thoroughly when the top few centimeters of soil feel dry. Retama sphaerocarpa is drought-tolerant once established and prefers drier conditions.

Overwatering can lead to root rot, so ensure good drainage and allow the soil to dry out between waterings.

Prune lightly after flowering to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches.

Heavy pruning is best done in late winter or early spring before new growth begins to shape the plant.

Easily propagated from seeds sown in spring, which may require scarification or stratification. Cuttings can also be taken from semi-hardwood in summer and rooted in well-draining soil or a sand-based medium.

Young plants may need repotting every 2-3 years into slightly larger containers. Mature plants are generally best left in their pots or planted in situ, as they dislike root disturbance.

Repot only when necessary, preferably in spring.
