Time for planting lettuce in the open field in the north

Open-field planting of lettuce in the north usually takes place in spring and autumn. In spring, it is generally carried out in April and May, and in autumn, it is carried out in September and October. These two seasons are more favorable for its growth and development. In order to allow its seeds to grow normally, it is best to plant it when the weather is clear.

Method of planting lettuce in the open field in the north

1. Land preparation and fertilization: When planting lettuce in the open field, you need to choose loose, fertile, well-drained, slightly acidic sandy soil, deep plowing the selected land, and apply enough base fertilizer to increase soil fertility.

2. Process the seeds: Lettuce seeds need to be processed before planting. Soak them in clean water for about 6-7 hours. After the seeds absorb enough water, wrap them with a wet cloth and place them in an environment with a temperature of 20-25 degrees to germinate.

3. Planting: After processing the lettuce seeds, you can plant them. You can use the broadcasting method to evenly spread the seeds in the soil, cover them with a thin layer of soil, and water them to keep them moist.
