High-yield cultivation techniques for edible fungi and how to prevent yellowing leaves after flowers are moved indoors

1. Moderate watering. After flower pots are moved indoors, because the space is not as open as outdoors, the amount of water transpired from the pots and the surface of the plants decreases somewhat. If you still water as before, the overly wet potting soil will cause root rot, which will turn the leaves yellow.

2. Reduce fertilizing. After flowers are moved indoors, rising temperatures will bring them into a stage of rapid growth. But their absorption of fertilizer is not as great as in summer, so topdressing should be reduced or stopped to prevent the plants' leaves from turning yellow.

3. Adjust the light. If some flowers that like strong light, such as Chinese rose and hibiscus, are placed in a shaded spot after being moved indoors, the plants will mostly develop yellow leaves. Conversely, placing shade-loving plants such as bird's nest fern and Swiss cheese plant in a spot with stronger 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.

4. Ventilate the environment. When the environment is closed and stuffy, the ethylene content in the air gradually increases. At this time, many flowers that are relatively sensitive to ethylene will develop yellow leaves due to aging. Therefore, keeping good ventilation at all times is one of the effective ways to prevent yellow leaves on indoor flowers.

5. Maintain a suitable temperature. Because an unsuitable ambient temperature can also cause many flowers to develop yellow leaves, especially when the temperature difference before and after flowers are moved indoors is relatively large. If the lowest outdoor temperature is 5°C, move Milan and azalea into a greenhouse, and because no attention is paid to lowering the temperature, when the daytime ambient temperature rises to 25°C, the plants will soon develop yellow leaves. This situation also needs to be prevented.
