When is the best time to grow leeks?

Leek seeds can be sown in spring, summer and autumn, but the best time is between March and May in spring.

The climate in spring is conducive to growth and can germinate quickly. If you miss the best time in spring, autumn is fine, that is, around August. It is not recommended to carry out in midsummer or severe winter, which is very unfavorable for seed emergence.

It is suggested to accelerate germination, soak in warm water and sow after radicle elongation before planting. As long as you sow, cover with thin soil, water properly, and cover with plastic film to keep warm and moisturize, you will soon emerge.

Growth habit of leek

1. temperature: leek is cool, cold-resistant and heat-resistant. The suitable temperature for seed germination is above 65438 02℃, and the growth temperature is between 65438 05℃ and 25℃, and the underground part can bear lower temperature.

2. Illumination: moderate illumination intensity and strong negative resistance. However, the light is too weak, the accumulation of photosynthetic products is less, the tillers are few and weak, the yield is low, and it is easy to premature aging; Too much light, too high temperature, too much fiber and poor quality.

3. Moisture: The suitable air relative humidity is 60-70%, and the soil humidity is 80-90% of the maximum field capacity.

4. Soil nutrition: strong adaptability to soil texture, large fertilizer demand and strong fertilizer tolerance.
