You can see more light in spring and autumn, more sunshine near the south window in winter, and north windowsill in summer to block the light properly. When the light is suitable, the leaf color is gorgeous, and the light is too strong or too dark to make the leaf color lose its delicate and beautiful color.

3. Watering method. Watering to basin soil is suitable for dry and wet, in the growth process, spring and autumn is the peak season of growth and development, more water. The summer weather is hot, but the growth of the plant is slow because of the high temperature, which can be irrigated once in the morning or evening, high temperature and wet stems and leaves are easy to rot, depending on the weather and basin soil. The basin soil should be slightly dry, because its stems and leaves are fleshy, too wet and easy to make the roots rot, especially in winter due to low temperature, showing a dormant state, basin soil should be dry.

4. Fertilization method. Douban green is usually renewed once every 2 ~ 3 years. During the growth period, mature liquid fertilizer or nitrogen and phosphorus fertilizer was applied every 15 to 20 days, and the concentration was 15% 20% for cake fertilizer and 0.2% for 0.3% nitrogen and phosphorus compound fertilizer. If fertilization is not measured, it can reduce nitrogen fertilizer and make the markings on the leaves more significant.
