Cultivation methods and precautions of leaf lettuce

1. Soil

When growing leafy vegetables, it is best to choose soil with thick soil layer, good drainage and fertility. Generally, sandy loam is the first choice, as this type of soil can provide sufficient nutrients for leafy vegetables and make them grow more vigorously.

2. Water

Its root system is relatively developed and it likes to grow in a relatively moist environment. When the soil layer is dry, water it as soon as possible. When watering, you should choose the morning and evening time. The temperature is too high at noon. Watering at high temperature will affect the natural growth of leaf vegetables and cause damage to the plants.

3. Temperature

Leafy vegetable has a certain degree of high temperature resistance. Higher temperatures will promote the growth of its branches and leaves. The optimal growth temperature is 18-25℃. Too low a temperature will cause frostbite and affect its normal growth.

4. Nutrients

During the maintenance period, it should be ensured to absorb sufficient nutrients, and base fertilizer is generally used. Fertilization should be done after peeling the leaves, which can promote the formation and growth of new leaves and increase the yield of leaf vegetables. Be careful not to use concentrated fertilizer on the plants.
