Echeveria, with its unique leaf shapes and rich color variations, has become a favorite of many flower enthusiasts. Many enthusiasts encounter the issue of yellowing leaves during the cultivation process, which not only affects the ornamental value but also confuses the cultivators. Why do Echeveria leaves turn yellow? This article will unveil this phenomenon and provide corresponding preventive and treatment methods.
Reasons for Yellow Leaves in Echeveria1. Insufficient Light
Echeveria enjoys ample sunlight. If it is kept in a dark environment for a long time, the leaves will turn yellow due to lack of light, which is one of the most common reasons.
2. Improper Watering
Watering is a crucial aspect of Echeveria cultivation. Excessive or insufficient watering can lead to yellowing leaves. Excessive watering can cause root hypoxia, while insufficient watering will make the leaves lose water.
3. Soil Issues
Poorly drained soil, poor breathability, or high salt content in the soil can lead to yellowing leaves in Echeveria.
4. Pests and Diseases
Echeveria may be invaded by pests such as aphids and red spiders, or infected with diseases like leaf spot or soft rot, all of which can cause yellowing leaves.
5. Unsuitable Temperature
The suitable growth temperature for Echeveria is between 15-25°C. Too high or too low temperatures will affect its growth, leading to yellowing leaves.
Preventing and Treating Yellow Leaves in Echeveria1. Adjusting Light
Place Echeveria in a sunny location, ensuring at least 4-6 hours of direct sunlight daily. If there is insufficient light, artificial light sources can be appropriately increased.
2. Controlling Watering
Reasonably control the watering frequency based on the growth condition of Echeveria and soil moisture. Generally, keep the soil slightly moist and avoid waterlogging.
3. Improving Soil
Choose soil with good breathability and drainage, change the soil regularly, and avoid high salt content in the soil.
4. Preventing and Treating Pests and Diseases
Regularly inspect Echeveria and deal with pests and diseases promptly. Pesticides or fungicides can be used for prevention and treatment, while also maintaining a clean environment.
5. Adjusting Temperature
Place Echeveria in a suitable temperature environment to avoid damage to the plant caused by high or low temperatures.
The phenomenon of yellowing leaves in Echeveria may be related to various factors, including light, watering, soil, pests and diseases, and temperature.
