nanking cherry
(prunus tomentosa)
History
Prunus tomentosa has been cultivated for centuries in China, where it was valued as much for its ornamental qualities as for its edible fruits. Later introduced to Europe and North America, this small tree has seduced with its hardiness and abundant flowering, becoming an interesting choice for orchards and landscaping.
Origins
Native to China and other parts of East Asia, the Nanjing cherry tree is found naturally in temperate zones. It has adapted to the varied climates of its range and is known for its tolerance of cold winters, allowing it to thrive in environments where other cherry species may perform poorly.
Orchard Management
- En verger, le Prunus tomentosa est souvent planté en pleine lumière pour maximiser la floraison et la fructification. Il nécessite un sol bien drainé et fertile – idéalement légèrement acide – afin d’éviter l’engorgement. Un espacement d’environ 4 à 6 mètres entre les arbres permet de garantir une bonne circulation de l’air et de faciliter l’entretien, la taille et la récolte des fruits.
Physiology
- This deciduous fruit tree usually comes in the form of a shrub or small tree reaching 2 to 4 meters in height. Its foliage, characterized by a downy texture (hence its epithet « tomentosa »), is green in color and offers a nice contrast with its white to pinkish flowers in spring. Flowering, which precedes fruit formation, lasts a few weeks and attracts many pollinators.
Tree Management
- To obtain a balanced and productive tree, training pruning is recommended from the first years in order to promote aerated branches. Maintenance pruning in winter removes dead wood and directs growth towards fruiting branches. Regular management of the tree structure contributes to better light penetration and better canopy aeration.
Fruit Quality
- The fruits of Prunus tomentosa are small red to orange berries, with a thin skin and a tangy, fragrant flesh. Although they are modest in size, they offer a unique flavor that is reminiscent of both cherry and a slight plum note. Rich in vitamin C, these fruits are eaten fresh or used in the preparation of jams and juices, bringing a touch of exoticism to recipes.
Plant Protection
- Relatively hardy, the Nanking cherry tree tolerates climatic conditions well, but fungal diseases (such as mildew or powdery mildew) and insect pests should be monitored. Good cultural hygiene – removing dead leaves and managing irrigation to avoid excess moisture – is usually sufficient. In case of problems, preventive biological treatments can be applied to limit the risks without resorting to overly aggressive chemicals.
Harvest
- The fruit is usually harvested in late spring or early summer, as soon as the berries have reached full maturity and have their characteristic colour. Picking is done by hand to avoid damaging the delicate fruits. The fruits are then eaten fresh or processed into jams and juices, taking advantage of their unique flavor and nutritional qualities.
