Presentation of the Napoleon Cherry Tree for Apple Growers and Cherry Producers in France

The Napoleon Cherry is an old variety of Bigarreau , originating from Germany , dating back to 1785. Renowned for its large fruit , longevity and resistance to cold climates , it is particularly suited to commercial cultivation in France. This cherry tree produces fruit of high eating quality , which keeps well and is very versatile in cooking.

Characteristics of Fruits

Napoleon cherries are large , heart -shaped, with pale yellow skin speckled with red . Their flesh is white, firm and juicy , offering a sweet and slightly tart flavor. These cherries are ideal for fresh consumption , but also for processing into jams, preserves and pastries .

They have good shelf life , being able to be stored for several days after harvest. They withstand transport relatively well, which makes them an interesting choice for large-scale marketing.

Flowering and Pollination

The Napoleon Cherry tree is self-sterile , which means that it requires cross-pollination with other varieties to ensure good fruiting. Recommended pollinators include:

• Bigarreau Burlat
• Bigarreau Hâtif Delbard
• Bigarreau Hedelfingen
• Bigarreau Van

It flowers in April , which generally protects it from spring frosts and ensures good fruit set.

Growing Conditions

The Napoleon Cherry is a vigorous tree that adapts to different climates , including temperate, continental, oceanic and Mediterranean zones. It tolerates winter temperatures down to -20°C , making it a variety resistant to winter cold.

It prefers well-drained soils , rich in organic matter , with a neutral to slightly acidic pH. It has low tolerance to limestone , and additions of acidic organic matter (such as heather soil) may be necessary to prevent chlorosis .

The tree is sensitive to root asphyxiation , so it is essential to choose well-drained soil and avoid soils that are too heavy and compact .

Resistance to Diseases and Parasites

The Napoleon Cherry tree is relatively disease resistant , but it can be subject to certain common infections:

• Moniliosis , which causes the branches to dry out and the fruit to rot. It is advisable to apply preventive treatments with Bordeaux mixture and to remove infected fruit.
• Powdery mildew , which can be controlled with sulfur treatments.

Regarding pests , the tree can be attacked by:

• Black aphids , which weaken young shoots. Natural predators such as ladybugs and the application of black soap can limit their presence.
• The cherry fruit fly , whose larvae bore into the fruit. The use of yellow chromatic traps and the collection of fallen fruit can limit the infestation.

Regular pruning helps promote air circulation in the branches and limits the appearance of cryptogamic diseases.

Recommended Rootstocks

The choice of rootstock is essential for adapting the Napoleon Cherry tree to local conditions. In France, several rootstocks are recommended:

• Ceravium , a hybrid of cherry and morello cherry, offering good compatibility with all varieties of cherry trees and promoting rapid fruit set .
• Maxma 14 , a hybrid of cherry and Saint Lucia, which reduces the vigor of the tree while improving productivity and fruit size .
• Prunus mahaleb , suitable for dry and calcareous soils , although less recommended for heavy soils.

The choice of rootstock depends on the characteristics of the soil , the climate and the production objectives .

Harvest and Profitability

The Napoleon Cherry tree is harvested between the end of June and the beginning of July , which allows the season to be extended after early varieties such as Burlat .

Its average yield is 50 to 70 kg per tree , but it can be subject to an alternation phenomenon (high production one year, lower the following year). Rigorous management of the orchard, including balanced fertilization and appropriate pruning , makes it possible to optimize production from year to year.

Orchard Maintenance and Management

Light annual pruning is recommended after harvest to stimulate branching and improve fruit production. It is important to avoid excessive pruning, which could reduce fruit production.

Applying a balanced (NPK) fertilizer in early spring promotes flowering and fruit formation. Fertilization rich in potassium and magnesium also improves the taste quality of cherries .

Mulching at the base of the tree helps to retain soil moisture , prevent competition from weeds and reduce water evaporation in summer.

In the event of prolonged drought, additional watering may be necessary to avoid water stress and ensure good fruit set.

Conclusion

The Napoleon Cherry is an old and hardy variety of bigarreau , appreciated for its superior quality fruits , its adaptability to various climates and its longevity .

Its resistance to cold , good storage and late harvest make it a strategic option for producers wishing to extend the cherry season .

However, cross-pollination is essential , and it is crucial to choose a suitable rootstock to avoid problems related to limescale and root asphyxiation.

Rigorous orchard management , including disease and pest monitoring , helps ensure regular and profitable production for professionals in the sector.
