First of all, you need to consider what crops the onion will be planted after. The best beds are those after spinach, tomatoes, cucumbers, pumpkin or cabbage.
If you can't implement such a planting plan, you should prepare the beds in advance. According to experts who grow onions in the Chinese way, you should add 5 kilograms of humus with chopped onions to the soil in advance.
It is also advisable to add a tablespoon of superphosphate and a teaspoon of nitrophoska to each meter of land. You can add a couple of tablespoons of dolomite.
A few days before planting, the seedlings need to be warmed up for about 8 hours at 40 degrees.
It is recommended to remove excess scales and also cut off the dry part of the neck, but without touching the sprout.
After this, the bulbs can be soaked in warm water for a day. This should be done before planting.
When planting, it is important to remember that the holes should be 15 cm apart.
After a couple of weeks, you can add fertilizer. For example, a solution based on bird droppings will do.
