Temperature requirements. Garlic is a crop that prefers cold and cool conditions. It is suitable for lower temperatures during the germination and seedling stages, usually around 3-5 degrees Celsius, while the optimal growth temperature is between 12-16 degrees Celsius. At a temperature of 15-20 degrees Celsius, garlic expands the fastest.
Lighting requirements. Garlic is a long day crop that requires long days to sprout and promote the formation of garlic. When the sunlight is less than 12 hours, garlic cannot form.
Water management. Garlic has a smaller root system and weaker absorption capacity, so it has strict requirements for soil moisture. Before sowing and emergence, the soil should be moist. During the seedling stage, the soil should be dry and moist, while during the vigorous growth period of leaves, more water is needed.
Birth cycle. The growth cycle of garlic is usually divided into two stages, including the growth period and the maturity period. The growth period generally takes 4 to 6 months, and the maturity period takes 2 to 3 months.
Cold resistance. Garlic has good cold resistance and can grow in lower temperature environments. In winter, when the temperature is below 10 degrees Celsius, the above ground part of garlic will gradually wither, but garlic can still survive in the soil and resume growth in spring.
Strong adaptability. Garlic has strong adaptability and can grow in different types of soil and climatic conditions, but it is most suitable for growing in environments with temperatures ranging from 15 ℃ to 25 ℃.
Growth environment. Garlic is native to dry and cold Central Asia and has strong adaptability to soil and climate. It is generally suitable for growth in environments with temperatures ranging from 15 ℃ to 25 ℃. It prefers soft, fertile, and well drained soil.
Reproductive methods. Garlic is mainly propagated by dividing garlic. At the end of the growth period, the underground part of garlic gradually forms garlic heads, each containing multiple garlic cloves.
