Garlic can be planted all year round, but the best planting time is in late autumn and early winter, around 9- 10. Soon after planting garlic in late autumn, it will enter winter, and then it will go through low temperature in winter, which will help to complete garlic bud differentiation and grow garlic bolts and garlic heads in the next spring. It is suitable for growing in the environment of 15-20℃. The autumn climate is cool and suitable, the temperature is suitable, and it is easy to survive after planting. The climate in different regions is different, so the planting time is different. We should choose the planting time according to the local actual situation. The autumn climate is cool and suitable, and the temperature is suitable, so it is easy to survive after planting. Different regions have different climatic conditions, so the planting time is also different. For example, in cold areas such as Qinghai, Tibet and Northeast China, most of them are planted in spring.

If it is planted indoors, it can be planted all year round, regardless of the season.

Second, the growth habits of garlic

1, temperature: like cold and cool, the suitable temperature is -5-26℃. The 4-5 leaf stage of Allium sativum has the strongest cold tolerance and is the most suitable winter seedling age.

2, lighting: choose a place with sufficient light, long sunshine time.

3. Moisture: Garlic likes semi-dry and semi-wet soil.

4. Soil and nutrition: The fertile loam with a soil pH close to neutral, rich in organic matter, loose and breathable, and can be drained by drought and waterlogging is more suitable for the growth of garlic.

Three: garlic maturity

It takes more than 7 months for garlic to ripen. Garlic varieties can be divided into purple garlic and white garlic according to the color of bulb skin. The garlic cloves of purple garlic are few and large, with strong spicy taste and high yield, which are mostly distributed in North China, Northwest China and Northeast China, with weak cold tolerance, sowing in spring and late maturity. There are two kinds of white garlic: large petals and small petals, which are less spicy, colder than purple garlic, sown in autumn, and mature slightly earlier.

To sum up: garlic is usually sown in late autumn and early winter, that is, it is best to sow around September 9- 10/0; The maturity of garlic is usually 7 months, but there are also differences. The maturity of purple garlic and white garlic is different due to different sowing seasons.
