Common Walnut - Juglans regia

The Juglans regia, also known as the common walnut tree, is a deciduous tree of medium size with a majestic habit, cultivated for its hard and homogeneous wood as well as its oil-rich fruits, the walnuts. It is a broad and dense tree, with a short trunk and large, twisted, spreading, and highly branched branches. The medium green leaves, measuring 20 to 30 cm (8 to 12in), appear in May and consist of large and numerous ovate leaflets with smooth edges. The fruits appear in October. A countryside species widespread in our regions, it prefers full sunlight and requires a rich, deep, well-drained soil with enough moisture for good fruiting. It tolerates clay and limestone very well. Hardy down to -20°C, it still prefers mild climates and the hot, dry air of the continental climate. Not tolerating competition and inhibiting the growth of other species, it is a beautiful tree to plant in isolation, in the middle of a large meadow.

The Juglans regia is a majestic tree that requires space. No planting is possible below its canopy, as few plants can withstand its competition. The walnut, ready for harvesting in October, is large and oval with a soft shell. It is very good for drying, but it is even better when fresh. This variety bears fruit quite late, so expect about ten years before your first harvest.

Walnut trees in general prefer cool and deep but well-drained soils, as they are sensitive to stagnant moisture as well as prolonged droughts. A harsh winter can limit its fruiting and weaken the tree.
