Water Chinese Firethorn regularly, especially during dry spells and the first year after planting. Ensure the soil drains well to prevent waterlogging, which can lead to root rot.

Reduce watering frequency in winter once established, but do not let the soil become completely dry.

Prune Chinese Firethorn in late winter or early spring before new growth begins to shape the plant and remove any dead, damaged, or crossing branches. Summer pruning can be done after flowering to control size and encourage bushier growth, as well as to manage its thorny nature.

Propagate Chinese Firethorn from semi-hardwood cuttings taken in mid-summer. Dip the cuttings in rooting hormone and plant them in a well-draining medium. Keep them moist and provide a warm environment.

Alternatively, seeds can be sown in autumn, but germination can be erratic.

Repot Pyracantha only when necessary, typically every 2-3 years for container-grown specimens. Choose a pot that is only slightly larger than the current one.

Repotting is best done in early spring before active growth begins. Ensure good drainage in the new pot.
