Garlic likes cool climate. The suitable temperature for aboveground stem and leaf growth is 12- 16℃, and the optimum seedling age for overwintering is 4-6 leaves. It takes about 40-45 days from sowing to growing 4-6 leaves, and the growth stops when the daily average temperature is lower than 7℃.

3. The seedlings have strong cold tolerance, and can tolerate the low temperature of -7 ~- 10℃. At 0-4℃, the vernalization period can be passed after 30-40 days. Sowing early, easy to be frozen, sowing late because of the influence of high temperature in the later period, the production cycle is shortened, the yield is low and the quality is poor.
