Water regularly, especially during establishment and dry periods. Ensure good drainage to prevent waterlogging. Allow the top few centimeters of soil to dry out between waterings for established plants.

Reduce watering in winter.

Prune in late winter or early spring to remove dead, damaged, or crossing branches. Pricklyash can be pruned to maintain a desired shape or size, but it's generally a low-maintenance shrub.

Be cautious of the sharp thorns.

Propagate from seeds, which require a period of cold stratification. Alternatively, root cuttings can be taken in summer, or suckers can be transplanted in late winter or early spring.

Repotting is rarely necessary for this species as it is often grown in the landscape. If grown in a container, repot only when root-bound, typically every 2-3 years in late winter or early spring.
