Sweet Cherry (Prunus avium)
The Sweet Cherry (Prunus avium), commonly known as Wild Cherry or Sweet Cherry Tree, is a species belonging to the Rosaceae family. It is valued for the production of sweet and juicy cherries, as well as for its ornamental value, thanks to its abundant and decorative spring flowering.
Native to Europe and Western Asia, the Sweet Cherry is now widely cultivated in many temperate areas. The tree is known for the quality of its fruit, the beauty of its flowers, and its importance in both food and ornamental uses.
Botanical classification
Kingdom: Plantae
Order: Rosales
Family: Rosaceae
Genus: Prunus
Species: Prunus avium
Plant characteristics
Growth habit:
Prunus avium is a deciduous tree that generally reaches 10–15 metres in height. It has a broad, rounded crown and smooth grey bark.
Leaves:
The leaves are oval or elliptical, with finely serrated margins and a glossy green colour. They are arranged alternately on the branches and measure on average 7–15 cm in length.
Flowers:
Flowering occurs in early spring. The flowers are white or slightly pink, fragrant, grouped in small clusters, and composed of five petals.
Fruit:
The fruit is a drupe, commonly called a sweet cherry. The skin may be yellow, red, or dark purple, while the flesh is sweet, juicy, and contains a hard central stone.
Chemical composition and structure
Oils:
Cherry kernel oil, extracted from the seeds, contains fatty acids such as oleic acid and linoleic acid. Vitamin E is also present and is known for its antioxidant activity.
Vitamins and minerals:
Sweet cherries contain vitamin A, vitamin C, potassium, and dietary fibre. These components contribute to the nutritional value of the fruit.
Phenolic compounds:
Cherries contain phenolic compounds and anthocyanins, substances associated with antioxidant and anti-inflammatory activity.
How to grow it
Soil:
The Sweet Cherry prefers well-drained, fertile, sandy, or clayey soils. It grows best in soils with a slightly acidic or neutral pH.
Light:
It requires full sun exposure. For good fruit production, at least 6–8 hours of direct sunlight per day are recommended.
Watering:
It needs regular watering, especially during dry periods. However, waterlogging must be avoided, as it can promote root rot.
Propagation:
Propagation can be carried out by seed or grafting. Grafting is generally preferred because it helps maintain consistent fruit quality and plant characteristics.
Maintenance:
Pruning is useful for removing dry, damaged, or diseased branches, maintaining a good crown shape, and improving air circulation.
Curled leaves: probable cause and treatment
The problem of curled leaves at the tips of the branches is most likely caused by the black cherry aphid, rather than by a true fungal disease.
This pest mainly attacks young and tender leaves, causing curling, deformation, and leaf crumpling. As the tree grows and the leaves mature, the problem often tends to decrease because the tissues become harder and less attractive to aphids.
How to intervene:
Check the underside of the curled leaves for the presence of small black aphids.
Manually remove the most affected shoot tips if the infestation is limited.
Treat with potassium soft soap, making sure to wet the underside of the leaves well.
Repeat the treatment after 7–10 days, if necessary.
Check for the presence of ants, as they often protect aphids and encourage their spread.
In winter or late winter, before vegetative growth resumes, a preventive treatment with white mineral oil may be useful.
If the tree continues to grow well, the problem is generally not serious, but it is advisable to act early, as soon as the first deformed leaves appear.
Uses and benefits
Culinary uses:
Sweet cherries can be eaten fresh or used in desserts, jams, preserves, juices, sauces, and baked products.
Cosmetic uses:
Cherry kernel oil is used in cosmetics for its emollient, moisturising, and nourishing properties. It may be found in creams, lotions, balms, and hair care products.
Traditional uses:
Sweet cherries are appreciated for their antioxidant content and for their possible contribution to general well-being, mainly due to the presence of anthocyanins, vitamins, and phenolic compounds.
Applications
Food industry:
Sweet cherries are used as fresh fruit and as an ingredient in desserts, jams, preserves, juices, syrups, and beverages.
Cosmetics and personal care:
Cherry kernel oil is included in cosmetic formulations to improve skin softness, elasticity, and hydration.
Traditional and nutraceutical products:
Cherry extracts may be used in wellness-related products, especially due to their content of antioxidant substances.
Environmental and safety considerations
Environmental impact:
Sweet Cherry cultivation has a moderate environmental impact. Proper management of irrigation, pruning, and plant protection treatments helps reduce waste and unnecessary interventions.
Food safety:
Cherries are generally safe to consume. However, the stones contain amygdalin, a substance that can release toxic compounds if ingested in large quantities. For this reason, cherry stones should not be consumed.
INCI functions
Cherry kernel oil may be used as a skin conditioning agent.
In cosmetics, it helps improve skin tolerance to external factors and helps counteract skin dehydration. Its action is linked to the presence of lipid components with an emollient and nourishing effect.
It may be used in formulations for dry skin, moisturising products, face creams, body creams, lip balms, and hair care products.
INCI Functions: Skin conditioning agent.
