After garlic is harvested, the dormant period is usually two to three months. After the dormant period, under suitable temperatures, garlic seeds will quickly germinate and grow leaves, consuming the nutrients in the stems, causing the bulbs to shrink, wither, and their edible value is greatly reduced, or even rot. Therefore, although sprouted garlic can be eaten, its nutritional value will be greatly reduced due to depletion of nutrients, and its meat will become hollow and dry.
