Water Peking Cotoneaster regularly during its first year to establish a strong root system. Once established, it is drought-tolerant and prefers occasional deep watering during prolonged dry spells.

Avoid waterlogged soil, which can lead to root rot. Allow the soil surface to dry out slightly between waterings.

Prune Peking Cotoneaster to shape the plant, remove dead or diseased wood, and improve air circulation. For best flowering and fruiting, prune after the plant has finished blooming in late spring or early summer.

Light pruning can be done to maintain its size and form. Heavy pruning may reduce fruit production.

Propagate Peking Cotoneaster from semi-hardwood cuttings taken in mid-summer. Dip the cuttings in rooting hormone and plant them in a well-draining potting mix.

Alternatively, seeds can be sown in autumn, requiring a period of cold stratification to germinate. Seed propagation may result in variability.

Repot container-grown Peking Cotoneaster every 2-3 years, or when the plant becomes root-bound. The best time for repotting is in early spring before new growth begins. Use a well-draining potting mix.

Ensure the new pot is only slightly larger than the previous one to avoid overwatering issues.
