How to prevent the yellowing of leaves in flowers after bringing them indoors
Today, the editor will explain the common knowledge of flower cultivation and share the experience of preventing the yellowing of leaves in flowers after bringing them indoors. This method will surely be helpful to you, let's learn about it together!
In autumn and winter, as the temperature drops, many cold-sensitive flowers are moved indoors from outdoors. Although it is warm indoors, due to the sudden change in environment, many flowers will show signs of discomfort, especially the yellowing of leaves after entering the room is very noticeable. How to prevent the yellowing of leaves in flowers after bringing them indoors? The following will provide you with the answer.
1. Control watering: After moving indoors, due to the limited space compared to outdoors, the evaporation of water from the surface of the pot and plant decreases. If you continue to water as before, it can cause root rot due to the moist potting soil, and the leaves above the plant will turn yellow.
2. Reduce fertilization: In autumn, most flowers transition from vigorous growth to slow growth. After flowers are moved indoors, the rise in temperature may cause them to enter a rapid growth phase. However, their absorption of fertilizer is less than in summer, so it is necessary to reduce or stop top-dressing to prevent leaf yellowing in the plant.
3. Adjust lighting: Some flowers that prefer strong light, such as roses and hibiscus, if placed in a shady area after moving indoors, due to insufficient light, the plants may show yellow leaves. Conversely, placing shade-loving plants like bird's-nest fern and Monstera deliciosa in an area with too much light can also cause the leaves to lose their green color and turn yellow. The placement of indoor flowers should also be adjusted accordingly.
4. Ensure proper ventilation: A closed environment can lead to an increase in the concentration of ethylene, a gas that causes aging in flowers, in the air. At this time, many flowers that are sensitive to ethylene are particularly prone to yellowing. Therefore, maintaining good ventilation is one of the effective measures to prevent yellowing of indoor flowers.
5. Maintain a suitable temperature: Many flowers will turn yellow due to unsuitable environmental temperatures, especially when there is a significant temperature difference before and after the flowers are moved indoors. For example, if you move Milan or azaleas to a greenhouse when the minimum outdoor temperature is around 5°C and fail to cool down, and the environmental temperature rises to about 25°C during the day, the plant will quickly show yellow leaves. This situation also needs to be prevented.
