Walnuts are propagated by cuttings or cuttings, seeds or grafting. Seed propagation is the easiest way. To do this, select the seeds of large-fruited, high-yielding and frost-hardy trees.
Seed germination is retained for only one year. Walnuts intended for autumn sowing, can be sown without drying. Dig the garden bed to a depth of 30-40 cm, spread the seeds in the groove depth of 7-9 cm at a distance of 15-20 cm in the row and 50-60 cm between rows. After this the soil is compacted, and then tuck a fallen leaf or straw in winter with snow.
Seedlings appear in mid-may of the following year, during the summer the seedlings will grow up to 30 cm and form a good root system. If the winter was snowy with strong alternating frosts and thaws, autumn sowing may prove to be unsuccessful.

You should continue to keep the best plant. Nuts are placed in a triangle or a square whose side is equal to 20-25 cm, and after planting watered.
The seedlings are planted in spring, and the planting hole is prepared in the fall. 2/3 of it is filled with carefully peremeshennoi with a mixture of compost, fertile soil and peat in a ratio of 1:1:1, as well as fertilizers.
