"Green Ivy" Always Yellows in Winter
With the sudden drop in temperature, many plant enthusiasts have noticed that the leaves of green ivy are starting to turn yellow and wilt. As a common indoor foliage plant, green ivy requires special care during the winter. This article will reveal the methods to create three magical nutrient solutions, combined with scientific lighting management, to bring your green ivy back to life.
Secrets to Nourishing Green Ivy with Nutrient Solutions
Wonderful Use of Fermented Rice Water
The first-rate nutrient solution is rice water, which is rich in starch, vitamin B complex, and trace elements. Fermentation method: Fill a plastic bottle with rice water up to 2/3, add orange peel to reduce odor, seal it, and let it ferment in a cool place for 15 days. Dilute it at a ratio of 1:10 when using, and water once every two weeks. After fermentation, it becomes slightly acidic, effectively improving soil compaction, especially suitable for root absorption in winter.
Regulating Soil Acidity with Rice Vinegar
Rice vinegar solution is a powerful tool for adjusting soil pH. Mix 1 milliliter of salt-free rice vinegar with 500 milliliters of water, which can be used for both root watering and foliar application. It is recommended to use it once a month in areas with alkaline water in the north, as it can promote iron absorption and prevent yellow leaves. Avoid using industrial vinegar essence, and wipe the leaves after spraying to maintain their luster.
Beer Nutrition Supplement Technique
Expired beer contains amino acids and carbon dioxide, dilute it at a ratio of 1:20 before use. Two recommended methods: ① Use a cotton swab to wipe the leaves, which can remove dust and enhance photosynthesis; ② Dilute with water to promote microbial activity. Let the beer sit open for 24 hours to volatilize the alcohol before use, and apply once a month in winter.
Key Points of Light and Temperature Control

Scientific Lighting Strategy
Although green ivy is shade-tolerant, it still needs 2-3 hours of scattered light every day in winter. It is recommended to place it 1.5 meters away from the south window and use a white reflective board to enhance lighting. If it is continuously cloudy and rainy, you can use an LED plant growth light to supplement lighting for 4 hours a day, keeping the light 50 centimeters away.
Temperature and Humidity Control
Maintain the optimal growth temperature of 15-25°C and avoid direct cold wind. Ways to increase humidity include: ① Placing a wet pebble tray at the bottom of the pot ② Spraying in the morning and evening (avoiding at night) ③ Using a humidifier to maintain 50%-60% humidity.
By supplementing with nutrient solutions and managing lighting, combined with stopping the use of winter fertilizers, reducing watering frequency, and other measures, new leaves should sprout within 3-4 weeks. Remember to leave a 1-centimeter leaf stalk when pruning yellow leaves, as this promotes natural shedding and wound healing. By mastering these care tips, your green ivy will surely regain its lush green vitality.
