1, spring seed
Welsh onion is a common vegetable in life, which has a unique taste and is deeply loved by the public. So when is the best time to grow green onions? You can choose to sow in early spring, plant it in thawed soil, water it once in the morning and evening, and sprinkle some nitrogen fertilizer after watering, which will make the green onions grow faster.
Step 2 sow in summer
Welsh onion is a drought-resistant and cold-resistant plant. It is usually planted between June and July and can grow without too much watering. However, shading measures should be taken when planting in summer. When the sun shines strongly, the yield of green onions will decrease. Water it once every day after the sun goes down, and then apply diluted nitrogen fertilizer to the soil.
Step 3 plant in autumn
Autumn seeds are usually sown around June 5438+ 10. Autumn is the rainy season, with constant rain and high air humidity. You can choose to water once every three days and fertilize once a week. When the rainy season comes, we should do a good job of drainage and watering according to the soil moisture every day to avoid root rot caused by plants being soaked in rain for a long time.
4. The planting time of winter seeds is generally selected in early June, 5438+February. When planting green onions in winter, it is necessary to take cold-resistant measures, fertilize once every half month, water according to soil moisture, and apply a certain amount of potassium fertilizer every day, which is more conducive to the growth of green onions. When heavy snow comes, you can cover the soil with a film to avoid frostbite and let it survive the winter.
