First of all, you can check these white spots carefully to see if there are any pests or germs. If scale insects or fungal infections are found, corresponding preventive measures can be taken. In addition, if your plant is in a state of malnutrition for a long time, it may also lead to white spots on its leaves. In this case, we can consider providing plants with proper nutrition to promote their healthy growth.
In addition, environmental problems may also be one of the causes of these symptoms. If the plants are in too humid or dry environment, or exposed to too much sunlight, it may also cause the leaves to grow white spots and start to fall off. You can try to adjust the growth environment of plants to ensure that they are in suitable temperature and humidity conditions and avoid too much sunlight.
In a word, to treat the white spots and fallen leaves of this plant, we must first determine the specific reasons and then take corresponding control measures. If you are not sure about the cause, it is recommended that you consult a professional botanist or gardener for more detailed suggestions and treatment plans.
