Not all gardeners grow onions from sets. The most thrifty prefer to do it from seeds.
If you try, the onion will grow much larger and stronger than if you chose onion sets for this purpose. We will tell you about the best days for sowing black onions.
This is the same onion, only grown from seeds, which are small and black in this plant. Hence the specific name.
The beginning of March is considered the ideal time for sowing onions with seeds. Before transplanting, the seedlings grow on the windowsill, react normally to temperature changes, and do not need additional lighting.
It is important that the flowerpot is at least 12-15 centimeters high.
After a month, picking is carried out, but this is not necessary, however, the procedure allows you to grow large onions.
In March, you should not sow onions only on the 18th. The best dates are considered to be 7, 13, 15-16, 24-26, 29 and 30 March.
The seedlings are planted in open ground after the snow melts and warm weather sets in. The crop adapts well to cold weather even in cold soil.
There is no point in delaying the transplant. The hotter the weather, the worse the onion seedlings will take root.
