Onions are an unpretentious crop, but this does not mean that you can skip fertilizing.
It is thanks to the right fertilizers that you can get an excellent harvest of large onions. The feathers will be thick and green.
How to feed onions
In 10 liters of clean water, dissolve one tablespoon of potassium sulfate, magnesium sulfate, and ammonium sulfate. Add one teaspoon of copper and iron sulfate to this mixture.
If desired, you can add another 100 ml of liquid potassium humate to this fertilizer.
After this, when all the products are thoroughly mixed, you can proceed to watering the beds.
For every one and a half square meters of the plot you will have to spend about 10 liters of fertilizer.
It is better to apply fertilizers for the first time as soon as the outside temperature rises above 15 degrees. The procedure should be repeated in May. If the soil is poor, you can apply fertilizer in the first half of June.
