How and when to plant lettuce heads

The best time to plant lettuce heads

The suitable time to sow lettuce is around April in spring. The temperature and humidity at this time are more suitable for its seeds to germinate. It can also be done in autumn. The climate is cool at this time, which is also suitable for the growth of lettuce. If cultivated in a greenhouse, it can be done all year round.

Lettuce planting methods and key points

1. Sowing: The seeds of lettuce are relatively small and light, so they need to be mixed with fine sand and then sprinkled on the soil and covered with a thin layer of soil. It is best to treat the seeds before sowing so that they will germinate faster.

2. Transplantation: When the lettuce head grows 5-6 true leaves, transplant it and move it together with the old soil to a large pot. Wait for about a week to successfully acclimate the pot, and then provide brighter sunlight.

Points to note in daily management of lettuce heads

1. Temperature: Lettuce heads prefer a cool environment. The most suitable temperature is around 15 to 20 degrees Celsius. When the temperature is high, you should cool it down quickly to avoid sunburn on the leaves. If the temperature is low, you must take measures to keep warm.

2. Fertilizer: Lettuce has a great demand for fertilizer. Some organic fertilizer should be applied to meet its growth needs. When fertilizing, you can melt the fertilizer in water and then pour it into the soil. This can promote its absorption of nutrients.

3. Light: When growing, the lettuce heads should be placed in a sunny place, but the light should not be too strong, otherwise the leaves will turn yellow. However, they cannot be deprived of sunlight for a long time, otherwise they will grow poorly and the yield will decrease.
