The causes and treatment of yellow camellia leaves

1. Excessive watering

1. Reason: Camellia likes a humid environment, but excessive watering can easily cause waterlogging in the soil, causing the roots to become waterlogged and rot, leading to yellow leaves.

2. Treatment method: First, stop watering, then turn over the soil and place it in a cool, well-ventilated place for maintenance for a period of time. After it slowly recovers, you can resume watering as normal. The soil needs to be kept moist, but not waterlogged.

2. Unsuitable soil

1. Reason: Camellia is suitable for growing in acidic soil. If the soil is alkaline or the nutrients in the soil are gradually depleted, resulting in insufficient nutrients, it will easily cause the leaves to turn yellow.

2. Treatment method: Change the flower soil regularly and pay attention to the nutrients in the soil. It needs to be regularly replaced with slightly acidic soil rich in humus. Before replacing the new soil, the new soil needs to be exposed to the sun for disinfection to prevent the occurrence of diseases and pests.

3. Normal Metabolism

1. Reason: Camellia is an evergreen plant. Its leaves generally do not fall off in a short period of time, but leaf replacement may occur. During the leaf replacement period, the leaves will turn yellow, which is normal.

2. Treatment method: If this phenomenon occurs, no special treatment measures are required, normal maintenance will be sufficient.

4. Lack of Growth Elements

1. Reason: Camellia needs some growth elements during its normal growth period. If there is a lack of nitrogen, yellow leaves will appear.

2. Treatment method: At this time, just supplement it with the required nitrogen elements. You can apply decomposed bean cake water once a month or add 1% ferrous sulfate solution.
