Reasons for the blackening of clematis leaves1. Disease infection
The most common cause of blackening of clematis leaves is disease infection, such as fungal diseases like black spot and anthracnose, as well as bacterial diseases, which can all lead to blackened leaves.

Too much or too little watering can cause the blackening of clematis leaves. Excessive watering can lead to root hypoxia, affecting nutrient absorption; insufficient watering can cause leaf dehydration and subsequent blackening.
5. Environmental factors

When nitrogen is insufficient, the amount of nitrogen fertilizer can be appropriately increased; when phosphorus and potassium are insufficient, an appropriate amount of phosphorus and potassium fertilizers can be applied.
3. Adjusting lighting
Place clematis in a sunny location, avoiding long periods of time in a dark environment. Be careful to prevent direct sunlight to avoid leaf burn.
4. Controlling watering
Water according to soil moisture, promptly drain excess water when watering too much, and increase watering frequency when watering is insufficient.
5. Improving the environment
