As winter approaches, many plants begin to show different postures. Geranium, a common household potted plant, is prone to leaf discoloration in the cold winter. This not only affects its ornamental value but also confuses many plant enthusiasts. This article will delve into the reasons for geranium leaf discoloration in winter and provide corresponding care tips to help your geranium remain vibrant in the winter.
Reasons for Geranium Leaf Color Change in Winter1. Insufficient Light
Geranium is a light-loving plant. In winter, when the intensity of light is weakened, it can easily lead to yellowing or reddening of the leaves. This is because insufficient light affects the plant's photosynthesis, which in turn affects its growth and nutrient absorption.
2. Temperature Fluctuations
In winter, the temperature is relatively low with significant fluctuations. Geranium is sensitive to this and can easily lead to leaf discoloration. In low temperatures, the plant's metabolism slows down, resistance decreases, and leaves are easily damaged.
3. Improper Water Management
In winter, water evaporates more slowly. If watered excessively, it can lead to root hypoxia, causing leaves to turn yellow and fall off. Conversely, if watered too little, leaves will also turn yellow due to lack of water.
4. Improper Fertilizer Application
In winter, the growth rate of geranium is slower. If excessive fertilizer is applied, it can easily lead to leaf burning. Too much nitrogen in the fertilizer can also cause leaves to turn yellow.
Geranium Winter Leaf Color Change Care Tips1. Provide Sufficient Light
In winter, the intensity of light is weakened. Geranium should be placed near windows indoors to ensure adequate light exposure. In case of continuous cloudy and rainy weather, plant growth lights can be used to supplement light.
2. Control Temperature
In winter, the temperature is low. Geranium should be placed in a warm environment, maintaining the room temperature above 15°C to avoid leaf damage due to low temperatures.
3. Reasonable Watering
In winter, water evaporates more slowly. The frequency of watering should be reduced, keeping the soil slightly moist. Watering should be done on sunny days as much as possible, avoiding rainy days.
4. Moderate Fertilization
In winter, the growth rate of geranium is slower. The amount of fertilizer applied can be appropriately reduced. A low-nitrogen, high-phosphorus and potassium compound fertilizer can be chosen, applied every 20 days.
5. Pay Attention to Ventilation
In winter, indoor air circulation is poor, which can easily lead to leaf diseases in plants. Indoor air circulation should be maintained, and windows should be opened regularly for ventilation.
Geranium leaf discoloration in winter is a common phenomenon. Understanding the reasons and taking corresponding care measures can help maintain its beauty. Through the introduction of this article, it is believed that you have mastered the reasons for geranium leaf discoloration in winter and the care tips, allowing your geranium to remain vibrant in winter.
