The growth process of garlic includes 6 periods such as budding period, seedling period, bulb bud floral differentiation period, garlic moss elongation period, bulb expansion period and dormancy.

Leaf unfolding belongs to the budding period, which generally takes about 7-30 days, and after budding, it enters the seedling period with growth, and the leaf area gradually increases. Subsequently entered the flower bud and scale bud differentiation period, this is the key period of fertility. After the differentiation is completed, it comes to the period of garlic shoot growth, and then to the period of bulb expansion, and the garlic head underneath grows gradually. Wait until the plant withers and enters the physiological dormancy period.

The length of the garlic growth process varies greatly depending on the sowing period. Spring sowing garlic fertility period is short, 90~100 days, fall sowing garlic fertility period is long, 220~240 days. Garlic sprouting from the lifting of dormancy to the first leaf sowing generally takes about 10~15 days. Seedling period from the beginning of the expansion of the primary leaves open to growth to the leaves are no longer differentiated, autumn sown garlic 5~6 months, spring sown garlic about 25 days. Flower buds and bulbous bud differentiation period for flower buds, bulbous bud differentiation began to the end of the differentiation, the production is called the petal period, usually takes 10~15 days.

Garlic moss growth period refers to the beginning of garlic moss growth, to garlic moss dumping end of the harvest period, this time is the bulb bud expansion of the pre-scaling period, lasts about 30 days. Bulb expansion period from the end of bulb differentiation to bulb harvest, the period lasts 50 ~ 65 days, of which the first 30 days overlap with the garlic moss growth period.
