Prickly AshZanthoxylum oxyphyllum

Water regularly during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering in fall and winter. Ensure good drainage to prevent waterlogged roots, which can lead to rot.

Established plants are somewhat drought-tolerant.

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

Light shaping can be done after flowering if desired, but heavy pruning is generally not needed.

Propagation is typically done by seeds sown in fall or by root cuttings taken in late winter. Seeds may require stratification.

Alternatively, cuttings can be taken from semi-hardwood in summer, though this method can be less reliable.

Repot young plants every 2-3 years in spring, or when root-bound. Mature plants generally prefer to be left undisturbed. Use a well-draining potting mix. Avoid disturbing the roots excessively during repotting.
