Growing onions from seeds in one year
Onion is a relatively cold-resistant plant. Onion shoots can endure short-term frosts and lower temperatures. That is why it begins to land very early.
For growing onions, plots with rather fertile soil are chosen, where a large amount of organic matter was introduced. When preparing the site, the soil is dug to the depth of the entire fertile layer. Then, in early spring, urea, superphosphate and potassium chloride are added to the selected area.

In order for seedlings to emerge friendly and plants to grow faster, onion seeds are soaked for germination until white roots appear in the seeds and then dried to flow. Sow onions in the spring, early, in moist soil.
For sowing on the plot, beds of a quarter meter wide are planted and onion seeds are sown in furrows to a depth of 2 cm. Then the seeds are covered with earth and compacted. Above, onion crops are mulched with peat or humus. For a more even distribution of small seeds during sowing, they are mixed with sand or dusted with white tooth powder to make them white and clearly visible. The approximate consumption of onion seeds is 1 kg per 10 meters of beds, depending on the germination of seeds.
Onion shoots appear two weeks after sowing. During this time, many weeds sprout, which can drown out the tender shoots of onions. Therefore, even before the appearance of the first shoots, it is necessary to carefully loosen the aisles and weed.
For better growth, onions must be fertilized with organic and full mineral fertilizers. The very first feeding of onions should be done in the phase of three real leaves of slurry diluted 1: 5 with water with the addition of 30 grams of superphosphate or a chicken droppings in a ratio of 1:10. During the crust, the onions must be thinned out, leaving the plants 4 cm apart.

At the next feeding, mineral fertilizers are introduced - 30 g of superphosphate, 10 g of urea and 15 g of potassium chloride are dissolved in a bucket of water. One bucket of fertilizer is enough for 10 meters of beds. If the growth of plants is intense, then nitrogen fertilizers must be excluded. Since July, they are also not fed with nitrogen, but superphosphate and potassium chloride are added.
Bulb harvesting begins with lodging and yellowing of leaves at the end of summer. The onion pulled out with the tops is left on the bed for ripening for one week, and then the tops are cut and transferred to a ventilated room.
