There are black spots on the bottom of the camellia leaves. What's going on?

1. What happened?

There are some black spots on the bottom of the camellia leaves, which may be infected with leaf spot disease. Infection is most likely to occur in hot, humid and poorly ventilated environments. When the disease first starts, dark brown spots will appear on the leaves, which look like small black dots. After that, they will slowly increase in number and begin to expand and spread around, causing their number to increase, and then cover the entire leaf, eventually causing the leaf to wither and fall off. It spreads quickly and can infect other leaves, causing problems for the entire plant.

II. Treatment measures

1. Timely ventilation: Before the disease occurs, preventive measures should be taken to strengthen ventilation conditions and promote air circulation, which can reduce the possibility of this happening. 2. Control watering: Do not water too much at normal times to avoid water accumulation. Excessive water accumulation will cause the roots to rot, leading to bacteria infecting the plants. After being infected with leaf spot disease, you need to pay more attention to the application of water and do not splash water on the leaves, otherwise it will aggravate the disease.
3. Cut off diseased leaves: If the plant is accidentally infected with the disease, cut off the diseased leaves to prevent infection of other leaves and to inhibit the spread of the disease. 4. Spraying medicine: According to the severity of the disease, purchase relevant medicine for spraying.
