Description of your tree:
The common walnut (Juglans regia L.) is a large, deciduous tree, reaching a height up to 25-35 m and exceptionally a maximum trunk diameter up to 2m. It is long-lived: normally 100-200 years, but some specimens may reach 1000 years old. It has a deep root system, with a substantial tap root starting from the juvenile stage. The bark is silver-grey and smooth between deep, wide fissures. The leaves are 20-45 cm long, with 5 to 9 leaflets, the ones from the apex being larger compared with those from the base of the leaf. Crushed leaves have a scent like shoe-polish. The crown diameter of the common walnut is larger in relation to its stem diameter than any other broadleaf tree species used in Europe. The fruit ripens during hot summers and is a large rounded nut of 4-5 cm and weighing up to 18g. It may be propagated both by seeds and also vegetatively.
The common walnut is a demanding species and requires special site conditions. Usually grown in pure stands or as individual trees, rather than within mixed woodland, it needs a warm and sheltered site and a long growing season. It also prefers deep and rich soils, with pH values of between 6 and 7.5. It is light-demanding, highly susceptible to competition and sensitive to winter and late spring frosts. Older trees are however able to withstand winter temperatures as low as -30°C. Germination is improved in mild winters, indicating that a changing climate with warmer winters may prove beneficial to its establishment.
Walnut is very appreciated for its nuts, which are a highly nutritious food source. They are rich in oil composed of unsaturated fatty acids, proteins, vitamins and minerals. The kernels contain a wide variety of flavonoids, phenolic acids and related polyphenols, which have good antioxidant, anti-atherogenic, anti-inflammatory and anti-mutagenic properties. A diet rich in walnuts is also thought to have a cardiovascular protective effect. Bark or leaf extracts are used worldwide in traditional medicine to treat a variety of conditions including fungal infections such as Candida, to inhibit the growth of bacteria responsible for dental plaques and oral hygiene problems, or to increase the insulin level in diabetic patients. The wood of the walnut is highly prized, being strong, attractive and easy to work. Good quality logs are sold for veneer and can command high prices. It is also used in agroforestry.
The Franquette variety of the Common Walnut is a typical French variety which produce good quality nuts and it’s generally more resistant to the moths and their larvae.
