How many days does green onion grow?

The growth process of green onions, from sowing to the first true leaf emerging from the soil and straightening, is the period from planting to the cessation of growth before winter, which is the period of green onion formation. When the temperature rises to 7°C, the onions begin to turn green, and finally reach the flowering and seed-setting period.

Green onion growing season

The growing period of green onions is about 120-150 days, and green onions are generally sown in two seasons. The sowing time is different and the harvesting time is also different. Green onions sown in the autumn of the first year are generally harvested after May of the second year, and green onions sown in the spring are generally harvested after October. If they are used as winter storage green onions, the harvesting time of green onions can be postponed according to the air temperature.

Onion growing conditions

1. Soil: Green onions like to live in slightly acidic soil. The soil should be loose, fertile and have sufficient moisture. In addition to the fertility of the soil, before the green onions sprout, you should also pay attention to the management of the soil to avoid soil compaction that will lead to poor emergence.

2. Temperature: Green onions are cold-resistant and heat-resistant. They are not difficult to grow, but if you want to have a high yield, it is better to have a suitable temperature. The roots of green onions are basically distributed on the surface of the soil. They like moist conditions, but not excessive water accumulation. Therefore, the soil of green onions is required to be kept moist at all times, and there should be no water accumulation.

3. Light: Scallions do not require much light, because even when planted very densely, they still have a relatively good ability to accept light, so they can produce a good yield without very strong light.

Management of green onion during growth period

During the growing period of green onions, attention should be paid to fertilizer and water management. Green onions are fertilizer-tolerant crops. Generally, organic fertilizers can be applied in combination with phosphorus and potassium fertilizers, or ternary compound fertilizers can be used. Under the premise of balanced fertilization, attention should be paid to the application of potassium sulfate, which has obvious effects on increasing yield and improving quality.
