1、 Soil

When breeding, the soil should be loose, breathable and contain nutrients. Rotten leaf soil, garden soil and river sand can be used, and then mixed with an appropriate amount of cake fertilizer. In this way, the nutrients are sufficient and can meet its various growth needs. It is very suitable for planting black grass

2、 Watering

It likes a humid environment and should be watered more during maintenance. Usually once every three or five days in spring and every day in summer. Don't let the soil dry. However, after cooling in autumn, we should reduce the amount of water once a week. When plants stop growing in winter, water should be controlled

3、 Illumination

The growth of black grass needs sufficient light, but we should pay attention to avoid strong light. Therefore, it should be shaded in summer, and it can receive all day light in other seasons, especially in winter

4、 Fertilization

Fertilizer should be applied frequently in the growing season during maintenance. The frequency is about once a month. Nitrogen fertilizer is OK. However, it should be stopped before flowering and changed to cake fertilizer, once a half month. After the flower withers, apply fertilizer once, and stop fertilizer in winter

5、 Precautions

It grows fast, so it needs to change pots and soil once a year, preferably in the early spring. In addition, loosen the soil at the beginning of planting, and pay attention not to damage the root system
