1、 Transplanting time

When transplanting onions, we should avoid the cold weather, which can be carried out around November at the end of autumn. If it is transplanted at this time, it can enter the winter in the best state. If it is transplanted earlier, it is likely to have early stage in spring. If it is transplanted too late, it may also be frostbitten and cannot survive the winter normally

Generally, people will sow seeds in September in autumn, and it can be transplanted in about two months. In addition, when transplanting, it is necessary to screen out the seedlings with thin growth and diseases and insect pests, and try to transplant the seedlings with strong growth, which is also helpful for its later growth

2、 Precautions

1. Soil: the adaptability of onion is better, but the use of relatively loose and well permeable soil is more conducive to its growth

2. Keep warm: give it a mild environment in winter, so it will grow better. The most suitable temperature is between 16-28 ℃. Pay attention to keep warm in cold winter to avoid freezing injury

3. Watering: after the transplanting work is completed, the soil cannot be too dry. It needs to be properly watered, but don't water it immediately. Wait for it to slow down. In addition, it needs to be watered with green water in the coming spring, that is, from March to April
