1、 Suitable temperature

In summer, it is a top priority to ensure the appropriate temperature for Douban green. Watercress Green likes to be warm. The most suitable temperature for it is about 25 degrees. Because the temperature in summer is relatively high, it should be properly adjusted to the range suitable for it. When the temperature is very high, it should be properly cooled, such as placing it in an air-conditioned room. Generally speaking, it's best not to exceed 30 degrees, otherwise it will have an adverse impact on its health

2、 Proper lighting

Douban green also has requirements for light in summer, but it is afraid of strong light. The light in summer is sometimes very strong, especially at noon. Therefore, in order to be safe, it's better to choose a semi shady place to place it. If it is placed in direct light, remember to block out the strong light

3、 Proper moisture

The temperature is higher in summer, so the speed of water emission will be faster than that in other seasons. Therefore, water shortage should be supplemented in time, sometimes even twice a day. In addition, it is necessary to spray some water into the environment for humidification

4、 Proper ventilation

In summer, we should create a good ventilation environment for it. This has many advantages. It can not only provide good air, but also cool down to a certain extent due to the high temperature. Moreover, if ventilation is not timely, some diseases and insect pests may appear in the muggy environment
