With the arrival of winter, many green plants begin to enter a state of dormancy, and the green jade tree is no exception. Many green jade trees turn yellow in winter, which not only affects the beauty of the green jade tree but may also pose a threat to the health of the plant. This article will analyze the reasons why the leaves of green jade trees turn yellow in winter and provide corresponding countermeasures.
Reasons for the yellowing of green jade tree leaves in winter1. Insufficient light
In winter, the duration of daylight shortens, and the green jade tree receives less light, leading to weakened photosynthesis, which in turn affects the growth of the plant. Insufficient light can cause the leaves of the green jade tree to turn yellow.
2. Temperature changes
The temperature in winter is low, and the growth rate of the green jade tree slows down, as does its metabolism. If the temperature difference is too large, the green jade tree may show yellowing of the leaves.
3. Improper water management
In winter, the evaporation rate of water slows down, but the green jade tree still requires an appropriate amount of water. If watering is excessive or too little, it can lead to yellowing of the leaves.
4. Insufficient nutrient supply
The green jade tree needs sufficient nutrients during growth. In winter, due to the slow growth rate, the demand for nutrients decreases. However, if the soil lacks nutrients, it can still lead to yellowing of the leaves.
5. Pest and disease attacks
In winter, some pests and diseases, such as scale insects and red spiders, may attack the green jade tree, leading to yellowing of the leaves.
Countermeasures1. Adjust lighting
In winter, the green jade tree should be placed in a location with sufficient light but avoid direct sunlight. It is possible to appropriately increase indoor plant lighting equipment, such as LED plant lights.
2. Control temperature
Keep the temperature of the green jade tree's growing environment within an appropriate range and avoid large temperature differences. It is best to keep the indoor temperature between 15°C and 25°C.
3. Reasonable watering
Watering in winter should be moderate, keeping the soil moist. Excessive watering can lead to oxygen deficiency in the roots, affecting plant growth; too little watering may cause yellowing of the leaves.
4. Fertilization management
Apply fertilizer according to the growth needs of the green jade tree and soil fertility. In winter, a low-nitrogen, high-phosphorus and potassium compound fertilizer can be applied to promote plant growth.
5. Pest and disease control
Regularly inspect the green jade tree and deal with pests and diseases in a timely manner. Pesticides and fungicides can be used for prevention and control.
There are many reasons why the leaves of green jade trees turn yellow in winter, but as long as the correct maintenance methods are mastered, this phenomenon can be effectively avoided. It is hoped that this article can provide useful references for your green jade tree maintenance. Pay attention to green plant maintenance knowledge to keep your green jade tree vibrant even in winter.
