How to remedy the yellowing of gardenia leaves in winter?

Gardenia is a popular flowering plant loved for its blooming white flowers and rich fragrance. Many flower lovers will grow one or two pots of gardenias at home. Although it is relatively simple to maintain under normal circumstances, many flower lovers find that gardenias become difficult to care for in winter, and are prone to yellowing and falling leaves, which is largely related to low temperatures. Let’s learn how to remedy the yellowing of gardenia leaves in winter?

1. Temperature discomfort

Gardenia can tolerate temperatures close to 0°C and can usually spend the winter outdoors in Jiangsu and Zhejiang regions. When the temperature drops below 5℃, gardenia may have yellow leaves and fall leaves, which is a normal phenomenon. As long as the temperature is not lower than its cold resistance threshold, gardenia will not usually be frozen to death.

2. Adaptation problems caused by environmental changes

Although the temperature indoors is suitable, the ventilation conditions may not be as good as outdoors, and gardenias may need time to adapt to the new environment. In winter, plants adapt to the new environment more slowly, so a small amount of yellowing and falling leaves is normal and will not have much impact on the plants. When spring comes, the plants will recover quickly.

3. Improper watering

Gardenia likes a humid environment, but when it is kept indoors in winter, it should not be watered frequently. Excessive watering may lead to waterlogging and lack of oxygen at the roots, causing yellowing and leaf drop. If a large area of ​​yellow leaves and fallen leaves appear at the bottom of the plant and gradually spread upward, it may cause the death of the plant in severe cases. Faced with this situation, ventilation should be increased in time to accelerate the evaporation of moisture. If the plant has already become bare, it may still recover in the spring as long as the branches are not yet dead. When caring for gardenias indoors in winter, you should follow the principle of "water thoroughly when dry". Wait until the soil is completely dry before watering, and make sure to water thoroughly.

After understanding the situation, flower lovers don’t need to worry too much when encountering yellow leaves when caring for gardenias indoors. Find the root cause of the problem and take corresponding measures. As long as you ensure that the gardenia safely survives the winter and move it outdoors for maintenance after the temperature rises in spring, the gardenia will soon resume growing. Gardenia will grow very fast if it is adequately supplied with light, nutrients and water.
