The germination period of garlic is one week.

The germination time of garlic is related to the temperature. If the temperature is around 15℃, it will take a week from the time of planting to the emergence of sprouts. Garlic bought from the market, whether grown in hydroponics or soil, will take root and sprout within a week. It is better if the temperature is higher, which will shorten the time for new sprouts to sprout. However, garlic takes longer to germinate in winter when the temperature is lower.

Extended information:

Garlic likes cold and is more tolerant of low temperatures. It requires higher sunshine and high temperature to promote the differentiation of flower buds and scale buds. In addition, sandy loam soil is the best place for garlic to grow. Garlic grown in sandy soil has a strong spicy taste, but its texture is loose and cannot be stored well. Garlic has shallow roots and many root hairs. The root system has weak ability to absorb water and fertilizer, so it is not drought-tolerant. In different growth periods, garlic has different requirements for soil moisture.

The germination stage requires higher soil moisture to promote root germination; the seedling stage should not have too much water to prevent the seedlings from growing too long and promote the longitudinal growth of the root system; the post-mother, scale bud and flower bud differentiation stages require higher requirements. During the bulb expansion period, the soil humidity should be reduced to prevent the bulb skin from rotting and turning black.
