When thinning is done, the lettuce is mature and you can harvest the seeds from the top, air-dry them and store them, or sow them in time.

How to save seeds of lettuce

The thinned lettuce can be eaten. When the plant height is 20-30 cm, it can be harvested thinly. When the plant height is 35 cm, it should be harvested all at once. If the best harvest period is missed, it will become old and hard. The seed plants should be left to naturally sprout, bloom and bear seeds.

Lettuce seed planting

Lettuce seeds can be sown all year round. The temperature in the north is lower, so it is best to grow them indoors. The best time to grow them is August to September each year.

The seeds of lettuce need to be soaked in cold water for about 1 hour, and then placed in an environment of 15-20 degrees for germination. The seeds can be sown after they turn white. When the seedlings grow 2 true leaves, they can be thinned out and the soil should be kept moist. The plants cannot tolerate strong light and need to be shaded at noon. At the same time, attention should be paid to disease and pest control during the seedling stage.
