A large, broad-crowned deciduous specimen tree for open space, with leaves with 5-7 large oblong leaflets, aromatic when bruised. Yellowish catkins give rise to green, globose fruits that in good (and long!) summers ripen into edible walnuts. The nuts do not appear until the tree is approximately 15 years old. Juglans regia has deep roots and much prefers lighter soils that the roots can penetrate.
How to care for walnut common:
Though a relatively compact variety if left unpruned they can reach up to 6-7m tall when mature, however with regular careful pruning they can easily be maintained at around 3-4m tall. Regular pruning will also encourage bigger crops of nuts. Pruning should be undertaken between late summer and autumn to avoid excessive bleeding. When planting incorporate lots of well-rotted garden compost in the planting hole and stake firmly.

This tree is deciduous so it will lose all its leaves in autumn, then fresh new foliage appears again each spring.
