Cultivation methods and precautions of milk thistle

1. Soil

Milk thistle does not have very strict requirements on soil quality. It prefers flat terrain, good drainage and medium fertility. If the soil fertility is too high, it will seriously affect the growth of seedlings and be unfavorable for seeding. Generally, sandy soil is not suitable for growing milk thistle.

2. Fertilization

During the growth of milk thistle, attention should be paid to planting fertilizer and fertilizing. First, the land should be deeply plowed and then the soil layer should be turned over. Fertilization should be applied according to the barrenness of the soil. Generally, 18-20 kg of phosphorus and potassium can be applied per mu of barren land.

3. Temperature

Milk thistle is very cold-resistant. If the temperature is relatively low, its leaves will become darker. Once the temperature rises, the leaves will return to normal. Generally, the ideal growth temperature for milk thistle is around 15~20℃, at which its fruiting rate is the highest.

4. Watering

Milk thistle is very afraid of drought in the early stage, especially in spring, so it is necessary to water it in time and appropriately. However, do not water too much. In the later stage, you need to water it appropriately. A slightly moist state is better.
