2. Soil: the requirement of Solanum nigrum on soil is higher, but it needs to grow in the soil with rich organic matter, water and fertility to make it grow better. If in poor ventilation performance, organic matter is not rich in cohesive soil, it is easy to lead to poor development.

3. Light: Solanum nigrum prefers a well lit environment. It has a negative tolerance, but it can't be out of light for a long time. In its growth period and flowering time need to ensure enough sunshine, but the light is not easy to be too strong.

2. Pruning and coring: when the plant grows to about 8 to 10 knots, the top heart can be removed to allow enough growth space for the lateral buds. Wait until the lateral buds have 20 inside or so to trim, leaving only 5 cm, to promote the growth of new branches, dead leaves, etc. also need to be removed in time.

3. Proper fertilization: in order to keep the fresh shoots fresh and tender, and promote their continuous growth of new shoots, it is necessary to carry out fertilization after each harvest to promote their growth and development. This can also enhance its disease resistance and improve the quality of Solanum nigrum.
