Onion bulbs are planted in the fall, but green onions can be planted at any time of year. The best time to plant onion bulbs is from September to November. You can also plant them in December or January, but they may not produce as many onions as those planted in the fall.

If onions are planted in September, you can get a crop of onions in early spring. But for this kind of growing, you need to choose a variety that can survive the low winter temperatures. If you decide to choose a variety that is not winter-hardy, it should be planted from March to August. In this case, the harvest will be possible in 8 weeks after planting.

Tips for planting onions:

  1. Onions should only be planted in well-drained soil, and very fertile soil. Before sowing, the soil should be well loosened and an all-purpose fertilizer should be added. This should be done 1 week before sowing onions.
  2. After that, start making hollows in the soil about 1.5 cm, with a distance of 15 cm between them. Then start sowing the seeds in a thin layer.
  3. Remember that green onions do not tolerate too much water. So it is important to make the soil well drained. Make sure that there are no weeds in your vegetable garden. Weeds quickly kill onions. Young shoots are also very attractive to birds, so it makes sense to cover the seedlings with a garden blanket.

Onions should be watered regularly, but not too often. Water the onions every day for about two weeks and then do it every other day. During dry periods, it may be necessary to water them twice a day. When watering, soak the soil well so that the water penetrates deep into the soil. It is important to avoid wet puddles – this can cause root rot onions as well as other diseases.

The disease also affects the top of the onion, turning it yellow. After a while, the onion will begin to wilt.

  3. Take a glass, jar or bottle with a wide neck, put our fruit inside and pour water. The water should completely cover the roots of the onion;
  4. As the green feathers leaves grow, you can cut them off and eat them;
  5. Change the water every 2-3 days;
  6. If you cut off the leeks, the onion will produce new ones until the head is no longer yielding. In this case, it is recommended to replace the fruit.
