All seeds of onion-sowing up to 1 cm in size at home can not be kept until the spring.
They will dry completely, and then they will be released.
Therefore, they must be planted in the ground under the winter.
Bulbs will winter well and at the end of July they will give a good crop of turnip.
But at the same time there is a small difference in agricultural technology in comparison with the spring planting.
In the beginning, the soil must be disinfected with a solutionCopper sulphate. In 10 liters of water, dissolve 1 tbsp. L. Copper sulphate, and this solution is watered onion beds. Then for every square meter a bucket of humus is poured, 2 tbsp. L. Superphosphate, all this must be digged and leveled with rakes. After leveling, make grooves 5 cm deep with a row spacing of 18-20 cm. In these grooves after 4-5 cm, spread out the sowing and fill with peat-and-spray mixture. If there is no peat, then you can fall asleep with one humus.
Remember the main rule. Before freezing, fill the entire bed with any insulation: peat, sawdust, humus, pine tartar layer 3-4 cm to keep the onion from freezing. Early in the spring, this shelter should be removed for the purpose of better warming the soil and obtaining uniform shoots. In winter, at a very low temperature, warm the bed additionally with snow.
In spring, the thickened onion is thin and used for food, leaving a distance between plants 5-6 cm. Planted on winter, the onions are kept better than the onion of spring planting.
