Common walnut is a native tree of the Old World. Its natural habitat lies between South-eastern Europe and Himalayas. Irrespective of its large size it is still one of the most sought-after fruit trees of our country.
Walnut has attractive, pinnate foliage that have a unique scent. Flowers are catkins. Both the leaves and flowers emerge late but yet may be damaged by late frost should it come in May when the leaves and flowers have come out. Fruit is a well-know walnut in a hard shell. This species ripens in October and sets fruit when 8-10 years old. Self-fertile.
Walnut is a large tree that needs space. It can grow 20m tall and wide and offers medium-deep shade. Its leaves cannot be composted. Pruning, if needed, can be done at the end of winter. Remove dead or damaged branches in late summer to prevent bleeding. It will grow in almost any well-drained soil but will thrive in deep and fertile soil, in full sun. Fully hardy to about -30°C (USDA zone 5).
