What is the planting time and method of onion seedlings?

The planting time of onion seedlings is generally in autumn, and it can be planted in autumn and winter in southern China.

Soft and nutritious soil with good drainage and air permeability can be used when planting onion seedlings; Give it some scattered light every day, and it will grow well; Relatively cold-tolerant, the optimum temperature for germination is 13℃-20℃, and the growth rate will decrease when it exceeds 28℃. Because the root system is sparse, the water demand is not enough.

Planting method of onion seedlings:

1. Soil: I like soft, nutritious soil with strong drainage and good air permeability, and it is not suitable for planting in sandy soil.

2, lighting: it prefers mild scattered light, if the light is too strong, it needs shading, otherwise there may be yellowing leaves, increased fiber, poor taste and so on.

3. Temperature: I like cooler climate and have strong cold resistance. The optimum temperature for germination is13℃-20℃; During the stem and leaf growth period, 10℃-23℃ is the best, and when it exceeds 28℃, the growth rate will obviously decrease.

4, watering: the root system is sparse, less water than green onions, but not drought-tolerant, the soil should be kept warm.

5. Fertilization: Spring and summer are its growing periods, and topdressing can be done 1-2 times as appropriate. The first topdressing can be in 20-25 days and the second topdressing can be in 12- 15 days.
