Garlic generally takes more than 200 days to mature after sowing, and can be harvested in spring and summer. If the seeds are sown earlier, they may grow too fast and consume too much nutrients, making it difficult to survive the winter.
The cultivation season of garlic varies with the climate in the north and south. In the area south of 35 degrees north latitude, winter is not cold, and seedlings can overwinter in the open field, usually sowing in autumn; In the northern area of 38 degrees north latitude, the winter is very cold, and autumn sowing seedlings are vulnerable to freezing injury, so it is suitable to sow in early spring; North latitude, 35-38 degrees, can be planted in spring and autumn.
