Water Daphne tangutica regularly, ensuring the soil remains consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out slightly between waterings.

Reduce watering in winter when the plant is dormant, but do not let the soil become completely dry. Overwatering can lead to root rot.

Prune Daphne tangutica immediately after flowering to maintain its shape and size. Remove any dead, damaged, or crossing branches. Light pruning can be done to encourage bushier growth.

Avoid heavy pruning, as this plant does not tolerate it well and can be slow to recover.

Propagate Daphne tangutica from semi-hardwood cuttings taken in mid-summer. Dip the cuttings in rooting hormone and plant them in a well-draining, moist compost. Cover with a plastic bag to maintain humidity.

Rooting can take several weeks to months. Seeds can also be sown but require stratification.

Repot young Daphne tangutica plants every 2-3 years in spring. Use a well-draining, slightly acidic potting mix. Choose a pot that is only slightly larger than the current one.

Mature plants generally prefer to be left undisturbed and can be top-dressed with fresh compost annually.
