With the arrival of winter, the leaves of many potted plants begin to turn yellow, which not only affects the beauty of the potted plants but also confuses the caregivers. What are the reasons for the yellowing of potted plant leaves in winter? How to prevent and solve this problem? This article will reveal them to you one by one.
Insufficient lightingIn winter, the sunlight is weak, and many potted plants cannot perform photosynthesis sufficiently due to insufficient lighting, causing the leaves to turn yellow. Solution: Move the potted plants to a sunny area or use artificial light sources to supplement the lighting.

Improper wateringIn winter, the temperature is low, and the evaporation of soil moisture is slow. If watered too much, it can easily lead to root hypoxia, which in turn causes the leaves to turn yellow. Solution: Reduce the watering frequency appropriately and keep the soil slightly moist.
