1、 Too much light

1. Reason: rubber trees are suitable for growing in an environment with soft sunlight but no strong direct light. If the environmental light is strong, it will burn its leaves and turn yellow

2. Treatment method: if it is convenient to move, the flowerpot of the plant can be directly moved to a semi shady place and maintained slowly. If it is inconvenient to move, you can set up a shading net to block the strong light and protect its leaves

2、 Excessive watering

1. Reason: if it is often watered excessively during breeding, its flower soil is often in a state of ponding. Its root system may suffer from waterlogging and cannot normally absorb water and nutrients in the soil, resulting in yellow leaves

2. Treatment method: first take the plant out of the original flower pot and cut off the waterlogged roots. After that, plant it into new flower soil that is not easy to accumulate water, and reduce watering until it recovers

3、 Too little fertilization

1. Reason: its growth needs certain nutritional support. If you forget to apply fertilizer for a long time, it will lead to malnutrition and yellow leaves

2. Treatment: pour a small amount of diluted liquid fertilizer into its flower soil, and spray some low concentration foliar fertilizer on its leaves to provide nutrition. After that, slightly increase the number of fertilization, and then it can absorb nutrients and resume growth
