Crataegus pinnatifida (Chinese Hawthorn)


Michael's Opinion

The Chinese Hawthorn is an ordinary looking tree with minimal abstract features. The dark oak-like leaves contrast well with the pome like fruit, creating a very simple looking tree. Although the Chinese Hawthorn may be the star in the everyday landscape, there are a vast amount of medicinal and recreational uses. The fruit is believed to have been used to treat indigestion and heart tingling. The pome like fruit is also used in the everyday Chinese cuisine, which makes for a useful crop. This Hawthorn brings an elegant winter interest through its coloured and textured bark, adding some depth to a winter garden. It is also quite forgiving when it comes down to seed propagation and general maintenance. This ordinary looking tree in the summer holds many beautiful secrets through its fruit, seasonal interest and low demand nature, which allows for a useful tree regardless of horticultural knowledge.

It is also quite forgiving when it comes down to seed propagation and general maintenance.
PropagationThe main method for propagation is by seed. When planting by seed, be sure to store the seed in the original packing in the refrigerator until it is time to plant, ideally in the fall. The germination process may take up to 18 months, to the next spring, in even moisture within a coldframe. Avoid temperatures below -5 C. When ready to plant, the seed will grow in good soil in full sun. You may also speed up the germination process by fermenting the seed in its own fruit pulp for a few days.
CultivationThe Chinese Hawthorn prefers partial shade to full sun. It prefers moist to wet soils, and can tolerate acidic to slightly alkaline soil. Best time to use a slow-release fertilizer is during the early spring, and it is ideal to prune dead/dying branches in the middle of fall. The tree is also wind, pollution, fire and drought tolerant.
PestsMembers of the Crataegus genus are susceptible to cedar-hawthorn rust, quince rust and fire blight. They are prone to leaf spot, apple scab, and powdering mildew, and will attract aphids, borers, leaf miners, lace bugs, spider mites, and scales.
