How and when to plant lettuce? When is the best time to plant lettuce?

Suitable planting time for lettuce

It is actually very easy to grow lettuce, whether in spring or autumn. Generally speaking, spring is around March or April, and it can be harvested after one month of growth. Autumn planting is usually in August or September, and it can be eaten around October.

Methods and key points of growing round lettuce

1. Seedling cultivation

Choose a suitable variety of lettuce according to local climate conditions, and then prepare nutrient-rich soil with good water permeability and air permeability as the culture soil. Sprinkle the lettuce seeds on the seedbed, cover it with a layer of fine soil, and cover the seedbed with a layer of film to keep it warm. Wait until the seedlings emerge from the soil to remove the film.

2. Planting

When the lettuce seedlings have grown five leaves, they can be transplanted and planted. Before planting, be sure to water the seedbed, which will increase the success rate of planting. It is best to plant them in ridges, which will increase the thickness of the soil and allow the roots of the seedlings to stretch better.

Points to note in daily management of lettuce

1. During the growth period, round lettuce has a relatively high requirement for water, so the soil must be kept moist. Usually, it needs to be watered once a week after planting. This will allow the lettuce to better survive the seedling period. The number of waterings will depend on the dryness and wetness of the soil. However, watering should be stopped just before harvesting.

2. The growth rate of round lettuce is relatively fast, so the demand for fertilizer will be relatively high, especially in the vigorous growth period. Nitrogen and potassium must be sufficient. In the later growth period, do not have too much nitrogen. Try to increase the amount of potassium fertilizer, which can make the lettuce head very well.
