How and when to plant lettuce

Lettuce planting time

The planting time of lettuce varies depending on the planting location. The best sowing season is March and April in spring and around September and October in autumn, because the temperature during these periods is basically stable at around 25 degrees, and the growth cycle of lettuce is 40-45 days, so it can be harvested just before the high temperature and frost come, which will not affect the yield.

Planting lettuce in spring

Lettuce can be planted in March and April in spring. The temperature during these periods is basically stable at around 25 degrees, which is suitable for the growth of lettuce. It can be harvested just before the high temperature comes, so the yield and quality will not be affected.

Planting lettuce in summer

The best time to plant lettuce in summer is mid-July. For summer planting, heat-resistant varieties need to be selected. In addition, suitable varieties must be selected according to local environmental conditions. The quality of the variety is the basis for determining the yield.

Planting lettuce in the fall

Lettuce can be sown in autumn from September to October. When sowing, spread the seeds evenly on the seedbed, cover them with soil, then cover them with a layer of decomposed farmyard manure, and finally cover them with a layer of plastic film. This can promote rapid germination of the seeds. When it grows two leaves, you can lift the film to prevent it from being burned.

Growing Lettuce in Winter

Winter planting can be done at the end of October. You need to choose a suitable planting site. Its absorption capacity is poor, and clay and thick soil cannot be selected, which will affect the yield. Therefore, it is best to choose soil with good air permeability, such as sandy soil or loam.

Lettuce Planting Method

Before planting lettuce, you need to choose suitable soil. It is suitable to plant in loose, fertile and well-permeable soil. The seedbed should be selected in a location with higher terrain and good drainage. The soil should be deep-turned in advance and ditches should be dug in the field to facilitate drainage.

After the lettuce grows 4-5 leaves, it can be transplanted. It is usually transplanted in the morning on a cloudy day, so that the survival rate of the transplanting will be guaranteed. When transplanting, the distance between plants is 30 cm and the row distance is 33 cm. Reasonable density can increase the yield of lettuce.

During the maintenance period of lettuce, sufficient water and fertilizer need to be provided, and weeding should be done in time. If you want the lettuce to grow well, it is generally necessary to carry out three top dressings. The first time is about 10 days after planting, applying manure and urine water, and applying urea when the plant height is 25 cm. When the lettuce stem swells, urea and potassium fertilizer can be applied. Each fertilization can be combined with watering and weeding.
