Reproduction
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.
Safer to do spring planting, but it will require careful storage of seeds. It is best to put the nuts in a single layer in wooden boxes, covered with wet sand and place in a cool place where the temperature is close to 0°C. For a month and a half before sowing, the boxes move to the room where supported +5-7°C. To increase humidity close to water left in an open container.
For planting walnut it is best to choose polozhennye place. When spring sowing distance in the row should be increased to 30 cm drilling depth should be 7-9 see If the nut is planted in a permanent place of growth, dig a pit of about 1 m, add a few buckets of compost, then place in the prepared planting 3-4 walnut. 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.
Features of cultivation and care
