The method in which onions are grown from seeds is the most economical - the seeds are inexpensive, gardeners can get them themselves on their own plot, and the process itself cannot be called labor-intensive. In addition, such a bow does not go into the arrow.
But there are features that are important to take into account to obtain the harvest of this crop.
Seed selection
If they are purchased at a gardening center or online store, you should pay attention to the expiration date. Onion seeds remain viable for 2 years, but even by the end of this period it decreases, and old seeds may not germinate at all.
Containers for seedlings
Containers for sowing onion seeds should be deep, about 15 cm. The fact is that this crop, even at the age of seedlings, has long roots - they need to develop in a large volume of soil. It is advisable to use drainage in the boxes - this way the roots will be protected from waterlogging, which is detrimental to them.
Sowing time
Do not delay sowing. If onions are sown in the garden, it is better to do this before winter. Even better is to use the seedling method. In this case, sowing in special boxes is carried out already in the second ten days of February. But at this time you cannot do without additional lighting. Otherwise, the seedlings will begin to stretch out greatly, and the seedlings will be thin and weak.
Correct picking
If seedlings require picking, it must be done carefully.The roots should not bend; when replanting, they are placed strictly vertically in the soil. Otherwise, they stop working and the plant may die. Some gardeners cut off the roots - this makes it easier to straighten them when transplanting into new soil. In addition, under no circumstances should seedlings be deeply buried; If the growing point is covered with soil, this will lead to its rotting.
Temperature for growing seedlings
One of the important points in cultivating onions. The fact is that if the temperature needed to germinate seeds is quite high - about +23-25 °C, then when seedlings appear, it needs to be reduced to +18 °C during the day and +10 °C at night. But there is one subtlety here - you cannot water the seedlings often at low temperatures, because the roots may rot.
Many gardeners have already switched to cultivating onions not in the traditional way from sets, but have learned to obtain large and even huge onions from seeds in one season. This significantly reduces the time and minimizes the efforts of gardeners when working with this crop, which is so necessary for our table.
