Lettuce is cool in nature.

1. How to care for asparagus

1. Substrate: Plant lettuce in slightly acidic soil, and it will grow better. You should choose well-drained, loose soil. Its roots are shallow and its absorptive capacity is relatively weak, so you can use sandy loam for planting.

2. Light: Lettuce is a plant that likes cool weather and cannot tolerate high temperatures. However, it also needs sunlight and good ventilation. Long-term sunlight will cause excessive growth.

3. Temperature: The temperature during the breeding period can be maintained at around 15℃-20℃. When the temperature is too high, it needs to be cooled down.

4. Moisture: Watering lettuce in the early stage of growth is neither dry nor wet, and requires sufficient water in the later stage. Lack of water will cause the stems to age and taste bitter. Just wait until the soil is dry before watering appropriately.

5. Nutrients: Fertile leaf water-soluble fertilizer can be applied appropriately to supplement nutrients.

2. Breeding skills

1. Sowing: Planting lettuce can be done in spring. Just place the seeds on the soil and cover them with a layer of film.

2. Overwintering: Lettuce cannot tolerate low temperatures. If it is grown in winter, it is best to put it in a greenhouse.
