Water Mediterranean buckthorn regularly during its first year to establish a strong root system. Once mature, it is drought-tolerant and requires watering only during prolonged dry spells.

Ensure the soil drains well to prevent waterlogging, which can lead to root rot. Overwatering should be avoided.

Prune Mediterranean buckthorn in late winter or early spring before new growth begins. This can involve removing dead, damaged, or crossing branches.

Pruning can also be used to maintain desired shape and size, or to encourage denser growth. Avoid heavy pruning in summer.

Propagate Mediterranean buckthorn from semi-hardwood cuttings taken in late summer or early autumn. Dip cuttings in rooting hormone and plant them in a well-draining potting mix.

Alternatively, seeds can be sown in autumn, but germination may be slow and erratic. Patience is key.

Repot young Mediterranean buckthorn plants every 1-2 years, or when they become root-bound. Mature plants in the ground rarely need repotting.

Choose a pot that is slightly larger than the current one and use a well-draining potting mix. Water thoroughly after repotting.
