How to solve the problem of leaves turning yellow and falling leaves

1, add water. The yellowing and shedding of leaves may be caused by low air humidity. At this time, it is necessary to replenish water. In the dry season, you should often spray water around the leaves with a watering can to increase the air humidity, prevent the leaves from turning yellow, and make the trees come back to life as soon as possible.

2. The light is too strong. Leaving trees in strong light for a long time will cause the leaves to turn yellow and fall off. At this time, it is necessary to shade them and cover them with a sunshade net to reduce the light intensity and let the trees grow normally in the astigmatism area.

3, suffering from pests and diseases. Trees infected with pests and diseases will cause the leaves to turn yellow. In the process of reproduction, it is necessary to prune frequently, cut off yellow leaves and dead leaves in time, and spray pesticides to prevent diseases. Trees can be watered with chlorothalonil solution once a month to avoid bacteria growing in the soil.

The temperature is too low. Most trees are not hardy. If the temperature is too low, the leaves will wither, turn yellow and fall off. Therefore, when cultivating trees, it is best to control the temperature above 10 degrees Celsius, and do not let them grow in a low temperature environment.
