Soil and fertilizer
Such crops require nutrient, sandy or loamy, friable soil, which will be well to pass the air flow to the root system. The recommended acidity level is 6.5-7 pH.
We advise you to read about what types of soil exist, how to improve soil fertility, how to independently determine the acidity of the soil at the site, as well as how to deoxidize the soil.
The best predecessors for onions are:
- cucumbers;
- potatoes;
- cabbage;
- tomatoes

Growing seeds at home
Grow "Setton" at home is not so difficult. The main thing is to prepare the seed correctly and to provide high-quality care for the seedlings.

Before planting, 3 hours later, the seeds must be placed in warm water, so that empty and unsuitable for planting specimens float to the top. For disinfection, planting material is soaked for another half an hour in a pink solution of potassium permanganate, after which it is washed and placed in hot water (about +50 ° C) for another 40 minutes.

Content and location
The material is planted in a pot with soil or peat cups. The perfect place - sill, sunny side.
Seed planting process

Seedling care
Before the onset of active growth, onions require regular abundant watering. For the first time after planting, plants are fertilized 10-14 days later with liquid organic matter.

Transplanting seedlings to ground
Onions are transplanted into open soil in early May, when its temperature exceeds the mark of +12 ° C. The soil is loosened beforehand and fertilized with organic matter. Do not forget to remove all weeds from the site.
Planting onions carried out with an interval of 9 cm between the bulbs. The recommended distance between the rows is 30 cm. It is possible to sprinkle the bulb on the ground with no more than 2-3 cm. It is better that all the beds are elevated.

The next stage is disinfection. It is carried out by treating the material with a manganese solution or copper sulphate. Additionally, you can handle special preparations to stimulate growth.
The process of planting sevka in the ground
