When is the best time to grow green onions in the north?

Green onions sown in autumn are generally harvested after May of the following year; Green onions sown in spring are generally harvested after 10 months.

Green onions are generally sown in two seasons, and the sowing time is different and the harvesting time is different. Green onions sown in the autumn of the first year are generally harvested after May of the second year. Green onions sown in spring are generally harvested after 10 months. If it is used as winter storage green onion, the harvest period of green onion can be postponed according to the temperature.

In rural areas, there is also a saying that "spring onions are not harvested at the autumnal equinox, and the first frost is empty", which means that when spring onions are harvested, most of them will be harvested at the autumnal equinox. If you can't harvest in the autumnal equinox, you can't delay harvesting until the first frost, because harvesting too late will easily lead to hollow green onions, which will affect the quality and yield of green onions.

According to the solar term temperature

Because there are many varieties of green onions, the area where green onions are planted is very wide, so we can judge the harvest time of green onions not only according to the solar term temperature, but also according to the growth of green onions. Generally, after the outer leaves of Chinese onion stop growing, the leaves can turn yellow-green, but they have not dried up, and they will be harvested before the soil freezes 15-20 days.

Correct harvesting methods for planting green onions;

When harvesting green onions, one side of the ridge of green onions can be hollowed out with a shovel, and then gently pulled up by hand after the green onions leak out, so that the soil at the root of green onions will not be broken at the same time, and then the withered yellow leaves on the epidermis will be removed, and generally 4-5 intact leaves can be kept in the middle, and then the whole green onions will be tied up with plastic woven bags.

Generally, it is 15 kg -20 kg. The green onions used for winter storage are relatively long, so it is better to tie them three times and firmly, but not too tight will crush the green onions and leaves, which will affect the quality and storage time of the green onions.
