1. Disease

(1) the first disease is called brown spot. This disease harms the leaves of plants and has a lot to do with watering. The specific prevention and control method is: it needs proper watering during its growth, and it is better to let the flower soil dry rather than make it too wet. If you water too much, it will cause the leaves to rot or turn yellow, affecting the beauty. In addition, when the summer air is relatively dry, water can be watered two or three times a day to ensure the exuberant growth of branches and leaves.

(2) the second disease is called downy mildew. To deal with this disease, first remove the diseased leaves, and then you can spray some disinfection drugs.

In addition, proper light is needed to increase the disease resistance of the plant. It is a green plant and needs to be protected by the sun, but direct light should be avoided. If the leaves are exposed to the sun, the leaves will turn yellowish or wither directly, which will make the plant suffer more. At the same time, it is also very shady, so when the plant has just entered the growth stage, it is best to carry out some shade protection, do not let the plant be directly exposed to sunlight.

2. Insect pests

The second way is to spray some medicine, usually omethoate, which is used every two weeks.
