2. How to plant green onions

1. Choose the variety: Choose the appropriate green onion variety based on your region and climate conditions. Some varieties are cold-tolerant, some are heat-tolerant, and some are suited to specific soil conditions.

2. Prepare the soil: Scallions prefer fertile, well-drained soil. Before planting, till the soil and add organic fertilizers such as compost or well-rotted animal manure to increase the fertility and organic matter content of the soil.

3. Sowing: Green onions can be sown directly by seeds or transplanted seedlings. Spring and autumn are suitable times for sowing. When sowing in spring, the soil temperature should be at least 7°C. The sowing depth is about 0.5-1 cm, and the row spacing is about 30 cm.

4. Seedling cultivation: If you start from seeds, you need to grow seedlings in a seedbed. Keep the soil moist until the seeds germinate. After germination, gradually reduce the amount of water to prevent the seedlings from growing too tall.

5. Transplanting: When the seedlings grow to 15-20 cm high, they can be transplanted to the field. Dig a hole about 10 cm deep at each planting site, place the seedling in the hole, make sure the roots are fully spread out, then cover with soil and compact lightly.

6. Planting spacing: Green onions need a certain amount of space to grow. The spacing between plants is generally kept at 10-15 cm, and the spacing between rows is 30-45 cm.

The above is an introduction to the latest time to plant green onions. Green onions can grow under a variety of climatic conditions, but the most suitable growth temperature is 15℃-25℃. The planting time of green onions is usually divided into spring, summer and autumn.
