Campsis, a kind of evergreen vine, is deeply loved by people for its brilliant purple flowers and graceful climbing posture. In the cold winter, many flower friends find that the leaves of Campsis begin to turn yellow, which not only affects its ornamental value but also makes maintainers feel confused. This article will unveil the reasons for the yellowing of Campsis leaves in winter and provide corresponding maintenance strategies.
Reasons for the yellowing of Campsis leaves in winter1. Insufficient light
In winter, the sun is weak, and if Campsis is exposed to insufficient light for a long time, it will cause the leaves to turn yellow. This is because insufficient light will affect the photosynthesis of the plant, thus affecting the synthesis of chlorophyll and causing the leaves to turn yellow.
2. Low temperature
In winter, the temperature is low, and Campsis may be affected by the low temperature, causing the leaves to turn yellow. Low temperature will inhibit the growth of the plant, causing the decomposition of chlorophyll, and thus making the leaves turn yellow.
3. Improper water management
In winter, the water requirement of Campsis decreases. If the watering is too much or too little, it may cause the leaves to turn yellow. Excessive watering can lead to root hypoxia, affecting the plant's absorption of nutrients; insufficient watering will cause the soil to dry, affecting the normal growth of the plant.
4. Improper application of fertilizers
In winter, the demand of Campsis for fertilizers decreases. If too much fertilizer is applied, especially nitrogen fertilizer, it will cause excessive plant growth and thus cause the leaves to turn yellow. Improper fertilization can also lead to high soil salinity, affecting plant growth.
Maintenance strategies for yellowing leaves of Campsis in winter1. Increase light appropriately
Place Campsis in a sunny location to ensure it receives at least 4 hours of direct sunlight daily. If maintained indoors, use a plant growth lamp to supplement light.
2. Control temperature
The suitable growth temperature for Campsis in winter is 15-25℃. It should be avoided to place it in an environment with low temperature. If the indoor temperature is too low, use a heater or air conditioner to adjust.
3. Reasonable watering
In winter, the water requirement of Campsis decreases, generally watering 1-2 times a week is enough. When watering, make sure the soil is moist but not waterlogged to avoid root hypoxia.
4. Apply fertilizers moderately
In winter, the demand for fertilizers of Campsis decreases. Reduce the frequency of fertilization. If fertilization is needed, choose a low-nitrogen, high-phosphorus and potassium compound fertilizer, applying once every two months.
5. Clean up the diseased leaves
If the leaves of Campsis turn yellow, clean up the diseased leaves in time to prevent the spread of the disease. Disinfect the diseased leaves to prevent the spread of the disease.
The reasons for the yellowing of Campsis leaves in winter are multifaceted, including insufficient light, low temperature, improper water management, and improper application of fertilizers. Understanding these reasons and taking corresponding maintenance measures will help improve the growth condition of Campsis, allowing it to remain vigorous in winter. I hope this article can provide you with assistance and wish your Campsis grows strong and healthy!
