Growing lettuce is actually very easy, whether it's in the spring or in the fall.In general, the choice of spring can be around March to April, when it grows for a month, it can basically be harvested.Autumn planting is usually in August and September, and it can be eaten almost in October.
1. Soil preparation: The soil for growing lettuce should be fertile. It likes acidity, so the pH value of the soil is the best between 5 and 7.Enough base fertilizer should be added to the soil, and farm manure can be added.
2. Seeds: Seeds should be selected before planting. Try not to use old seeds, so as not to affect the germination rate.When planting, we should soak the seeds for about 6 hours, then put them in wet cloth, adjust the temperature to 17 C, and plant them in about 3 days.
3. Planting: Mix the seeds with fine sand, then sow it into the ground. After planting, cover the seeds with 0.3-0.5 cm of soil.After covering soil, it is better to cover with plastic film, and the temperature should be adjusted to 18 -20 , and the temperature at night should not be too low, which is most suitable between 12 -14 .
4. Management: After planting, pay attention to ventilation, the climate should not be too hot, and pay attention to shading the seeds.When the seedlings grow out of 2-3 leaves, they should be thinned in time, otherwise their growth will be relatively thin and weak.
