1、 Maintain temperature

When Douban green is maintained in winter, the main maintenance factor is to keep the temperature well, and it must not cause frostbite to the plant. In the north, because the temperature in the growing environment is low, it is necessary to move indoors to keep warm. The temperature should be kept above 10 degrees Celsius. Generally, if there is heating at home, this requirement can be met. If the temperature in the south is a little higher, you can keep it outdoors directly, but you can put plastic bags on the plants to protect against the cold. Although kept indoors, be careful not to put it near the window in winter

2、 Plenty of sunshine

Although Douban green is afraid of exposure to the hot sun, the sunlight intensity in winter is small and will not cause damage to the plant. It can be raised in a bright place

4、 Stop fertilization

The growth rate in winter is very slow, and there is no need to apply fertilizer, especially when the growth temperature is relatively low

5、 Proper water spraying

The air in winter is relatively dry. You can spray water around the plant properly. Wipe the leaves with a wet cloth to keep them clean and promote growth
