Watering onions actually has a strong impact on the quantity and quality of the harvest.
It is important to know that onion leaves grow one from another - the leaf starts from the very root. Together they form a dense fruit.
In the first half of the growing season, from the moment the first leaf appears, the onion begins to actively grow foliage. Therefore, it is important to maintain soil moisture during this period.
The onion's root system is located in the upper layer of soil, so drying out occurs quite quickly.
You need to water until the first leaves appear. After that, the intensity of watering can be reduced.
You need to let the bed dry out between waterings, but it is wrong to completely stop providing the onions with water.
Fully formed onions ripen in the ground. It is better to reduce the amount of moisture to a minimum, since excess water will cause rotting.
To prevent rotting, you can trample yellowed leaves to the ground.
