What to do if the camellia leaves turn black and fall to the ground

1. Reduce moisture

Cause: When camellia leaves turn black and fall off, you can first observe the condition of the potting soil. If a large amount of water has accumulated in the potting soil, it means that you water it too much and the roots cannot absorb it. The water will accumulate at the roots, causing the roots to lack oxygen and be unable to breathe, and the leaves will naturally be affected.

Solution: If you find that there is too much water in the potting soil, you need to find a way to drain the water and temporarily stop all watering. It is also necessary to cooperate with ventilation and enhance air circulation so that the moisture can evaporate as quickly as possible.

2. Dilution Fertilizer Effect

Reason: The application of fertilizer is also one of the reasons. If the amount of fertilizer is too large, the roots will find it difficult to absorb it normally, which will cause excess nutrition and the roots will rot. If the fertilizer concentration applied is too high, it can also cause root burn.

Solution: Apply fertilizer correctly at ordinary times, do not apply too much fertilizer at one time, pay attention to the concentration, and do not use raw fertilizer. When the fertilizer concentration is too high, it needs to be diluted by watering in time.

3. Prevention and control of pests and diseases

Cause: The camellia leaves may turn black and fall off because they are infected with pests and diseases. For example, anthracnose will cause black spots to appear on the leaves, and pests such as scale insects will suck the juice and cause the leaves to turn black.

Solution: If you find such diseased leaves, you need to remove them in time to avoid infecting other leaves. And according to the symptoms, spray the medicine accordingly.
