Causes and treatments for yellowing cactus leaves

1. Excessive watering

1. Reason: Cactus is drought-resistant but not water-resistant. If it is watered too much and water accumulates, it will damage the root system, making it difficult for the plant to breathe and absorb nutrients, causing the leaves to turn yellow and fall off.

2. Treatment method: You need to control watering immediately, loosen the soil, increase soil drainage, and then place it in a ventilated environment to dry.

2. Excessive fertilization

1. Reason: Cactus does not have a strong demand for fertilizer. Too much fertilizer cannot be fully absorbed and will damage the root system, causing the leaves to turn yellow.

2. Treatment method: Stop fertilizing and water abundantly to allow excess fertilizer to flow out with the water, or flush the soil with water and then replant it in the pot.

3. Insufficient light

1. Reason: Cactus leaves are light-loving plants and need to be exposed to sufficient light during cultivation. If there is insufficient light, it will affect the normal growth of the cactus and cause the leaves to turn yellow.

2. Treatment method: The cactus needs to receive sufficient light to grow normally. If there is a lack of light, you need to move the plant to a ventilated and sunny place, or use fluorescent lamps and incandescent lamps to increase the light.
