Before sowing, prepare the seedbed for raising seedlings. Seedbed soil should be loose and fertile organic soil, or common loose soil mixed with organic fertilizer and Bika microbial agent should be poured once.

The seeds of lettuce are very small and light, so it needs to be mixed with sand, and then spread evenly on the seedbed, covering 0.5- 1cm of soil.

Step 4 raise seedlings

After sowing, keep the seedbed temperature at 12-20 degrees, keep ventilation and avoid sunlight. When the seeds germinate and grow two or three leaves, they can be planted.

Lettuce has a weak root system, so it should be planted with soil and seedlings. When planting, the row spacing and spacing should be 4x4cm. After planting, fertilize once and water again.

Step 6 harvest

Lettuce will grow quickly as long as there is enough fertilizer and water, and it can be harvested in 1-2 months. Be careful when harvesting, so as not to hurt the root and make it unable to continue to grow.
