Sowing

Onion is a vegetable that, in order to grow well and develop, needs a climate that does not present too many temperature ranges. It is resistant to the cold, but needs a few hours of natural light every day: when we choose the soil, it is therefore good to keep this need in mind, and to opt for a position in which the plants are exposed to the sun.

We must also avoid too compact soil: the onion needs light and well-draining soil, because it is necessary to avoid water stagnations, which would rot the plant. For this, the soil must be well prepared, digging and fertilizing it before sowing or planting the onions. It is recommended to do this a couple of months before the expected sowing date. The digging does not need to be too deep, as the roots of the onions do not sink very deep: about twenty centimeters will be sufficient. We recommend fertilizing with the manure, which is suitable for this type of vegetable.

It is advisable to plant the onions at the end of summer and at the end of winter: these two seasonal intervals have in fact the most suitable climate for these plants.

In the event that it was decided for sowing, it is sufficient to dig some shallow holes (about three centimeters), to put the seeds, which will then be covered with potting soil and watered.

Those who have only a terrace or a balcony at their disposal, know that the cultivation of potted onions is very difficult, because these vegetables require a lot of space. However, you can decide to try with very long rectangular pots, placing only a few seedlings in each pot.


Distance at which to plant onions

The holes must be about ten centimeters apart (same distance to be observed between the rows). If, on the other hand, the plants were sown in a seedbed, they must be extracted when they are about fifteen centimeters high, to be planted in holes about five centimeters deep.

For the planting of the bulbs, it is necessary to respect the distance of twenty centimeters between one and the other, and of about thirty between a row and the other. This type of cultivation is recommended above all for onions to be used fresh.
