Water Lycium shawii sparingly once established. Allow the soil to dry out completely between waterings, especially during its dormant period in winter. Overwatering can lead to root rot, so ensure good drainage.

In very hot, dry climates, occasional deep watering may be beneficial.

Prune Lycium shawii in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches. Light shaping can be done after flowering to maintain its form.

It is tolerant of hard pruning if necessary to control size or rejuvenate an old plant.

Propagate Lycium shawii from semi-hardwood cuttings taken in late summer or early autumn. Alternatively, seeds can be sown in spring, though germination may be erratic.

Cuttings generally root more reliably and produce plants true to the parent.

Repot established Lycium shawii plants only when they are severely root-bound, typically every 2-3 years. Use a well-draining potting mix. Repot in early spring before the onset of active growth.

This plant prefers to be slightly root-bound, so frequent repotting is not necessary.
