What are the methods to prevent yellowing leaves on indoor flowers?

People in cities nowadays like to grow flowers indoors, because it gives a warm feeling, but there are always one or two yellow leaves on the flowers, which makes the flowers look less bright and colorful. How do you prevent yellow leaves from appearing on indoor flowers? Here are five suggestions for everyone.

1. Control watering: after the plants are brought indoors, because the space is not as open as outdoors, the amount of water transpired from the flower pots and the plant surfaces decreases somewhat. If you still water as before at this time, root rot will occur due to the potting soil being too wet, and then yellow leaves will appear on the flowers.

2. Reduce fertilizing: in autumn most flowers shift from vigorous growth to slow growth, and after the flowers are brought indoors, the rise in temperature will make them enter a stage of rapid growth. But their absorption of fertilizer is still not as much as in summer, so topdressing should be reduced or stopped to prevent the plants from developing yellow leaves.

3. Ventilate the environment: a closed-in environment will cause the ethylene gas that makes flowers age to gradually increase in concentration in the air, and at this time many flowers that are relatively sensitive to ethylene are especially prone to yellow leaves. So always keeping good ventilation is one of the effective measures to prevent yellow leaves on indoor flowers.

4. Adjust the light: some flowers that like strong light, such as Chinese rose and hibiscus, will mostly develop yellow leaves due to insufficient light if they are placed in a shady spot after being brought indoors. On the contrary, placing shade-loving bird's nest fern and monstera in a place with too much light will also cause the leaves to lose their green color and turn yellow. The placement of flowers brought indoors should also be adjusted reasonably.

5. Keep a suitable temperature: due to unsuitable ambient temperature, many flowers will also develop yellow leaves, especially when the temperature difference before and after the flowers are brought indoors is relatively large. For example, if Milan and azalea are moved into a greenhouse when the outdoor temperature is about 5°C, and because no attention is paid to lowering the temperature, the ambient temperature is raised to about 25°C during the day, then the plants will soon develop yellow leaves. When this happens, it must also be prevented.

According to the above five suggestions, yellow leaves on indoor flowers can be effectively controlled, so that they look brighter and more colorful to us and give us a completely new visual experience.
