1、 Soil

Silymarin doesn't have a strict demand for soil. It prefers the land with flat terrain, good drainage function and medium fertility. If the soil fertility is too large, it will seriously affect the growth of seedlings and is not conducive to seed setting. General sandy land is not suitable for planting silymarin

2、 Fertilization

During the growth of silymarin, we should pay attention to planting fertilizer and fertilization. First turn the land deeply, and then turn over the soil layer. Fertilization should be carried out according to the barren degree of the soil. Generally, 18-20 kg of phosphorus and potassium can be applied per mu of barren land

3、 Temperature

Silymarin is very cold resistant. Usually, if the temperature is relatively low, its leaves will turn dark. When the temperature rises, the leaves will return to normal. Generally, the most ideal growth temperature of silymarin is about 15 ~ 20 ℃, and its fruiting rate is the highest at this temperature

4、 Watering

Silymarin is very afraid of drought in the early stage, especially in spring, so it should be watered timely and appropriately. However, do not pour too much water. In the later stage, it is necessary to water appropriately. The slightly wet state is better
