What is the reason why succulent leaves turn yellow and fall off?

Succulents have unique shapes and colors, and these different forms make succulents have high ornamental value. However, in the process of caring for succulents, you will find that some leaves turn yellow and fall off. So what is the reason why the leaves of succulents turn yellow and fall off? Let’s take a look below.

1. What is the reason why succulent leaves turn yellow and fall off?

1. The growth environment of succulents

Succulents like to grow in an environment with good ventilation, plenty of sunlight and moderate dryness. If the environmental humidity is too high, water droplets will easily appear on the leaves of succulents, causing the stomata on the leaves to become blocked, affecting photosynthesis and causing the leaves to turn yellow and fall off. In addition, if the growing environment of succulents is too cold or too hot, it can easily cause the leaves of the plants to turn yellow and fall off.

2. Metabolism of substances in plants

Succulents need to absorb a lot of nutrients during their growth, such as nitrogen, phosphorus, potassium, etc. If these elements are lacking, the plant will grow slowly and the leaves will turn yellow and fall off. At the same time, if succulents are over-irrigated or lack water during their growth, the leaves of the plants will turn yellow and fall off.

3. External factors

External factors are also one of the important reasons why the leaves of succulents turn yellow and fall off. For example, if succulents are attacked by insects or diseases, it will affect the plant's nutrient absorption and metabolism, causing the leaves to turn yellow and fall off. In addition, if succulents are exposed to strong sunlight, it is easy for the leaves of the plants to be sunburned, turn yellow and fall off.

2. What to do if the leaves of succulent plants turn yellow and fall off

1. Optimize the growth environment

For succulents, the most suitable growing environment is good ventilation, sufficient sunlight and moderate dryness. During planting and management, ensure that the plants are in such an environment. At the same time, care should be taken to avoid over-watering and over-fertilization, and to avoid environments with excessively high or low humidity.

2. Increase nutrient supply

Providing succulents with adequate nutrient supply is also key to preventing leaves from turning yellow and falling off. During the planting and management process, attention should be paid to providing the plants with appropriate amounts of nutrients such as nitrogen, phosphorus, and potassium to ensure their normal growth and development.

3. Prevent pests and diseases

Preventing pests and diseases is an important measure to prevent leaves from turning yellow and falling. During the planting and management process, pay attention to observe the growth conditions of the plants, promptly detect and deal with pests and diseases, and avoid their negative impact on the plant's nutrient absorption and metabolism.

4. Avoid exposure to the sun

Succulent plants should not be exposed to strong sunlight, otherwise the leaves will easily get sunburned, turn yellow and fall off. During the planting and management process, pay attention to controlling the intensity and time of sunlight to avoid damage to the plants.
