Water moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in winter to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, especially for potted specimens.

Prune in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches to maintain the plant's shape and health.

Light shaping can be done after flowering if desired to encourage a denser habit.

Propagation is best done from seed sown in autumn or by semi-hardwood cuttings taken in summer. Seeds require a period of cold stratification.

Cuttings should be treated with rooting hormone and placed in a well-draining medium.

Repot potted Rock Buckthorn every 2-3 years in spring, or when root-bound. Use a free-draining soil mix, such as a blend of loam, sand, and grit. Trim any circling roots to encourage healthier root development.
