1、 Cause of leaf loss

1. Lack of light: this kind of plant has a weak ability to resist the cold. If it is not placed in a place with the sun in winter, the leaves of the plant are easier to fall off, so it should be placed in a warm place with the sun in winter; If the leaves have fallen, it can also be transferred to a place with light at this time, so that the plant can grow new leaves

2. The temperature is too low: in winter, due to the relatively low temperature, the plant's ability to resist the cold is somewhat poor, so it is easier to freeze the plant if you don't pay attention to maintenance. In this way, the root of the plant can no longer absorb nutrients for the growth of the leaves of the plant, so the leaves will fall off. At this time, put the plant in a plastic greenhouse with a temperature > 15 ℃, so that the plant will grow new leaves again

3. Improper watering: it is necessary to keep the pot soil of the plant in a wet state in winter. If too much water is given to the plant in winter, it will affect the respiration of the plant root and seriously cause the loss of life of the plant. In winter, water the plants when the pot soil of the plants is dry

4. Excessive fertilization: this kind of plants have a high demand for fertilizer, but excessive fertilization may also lead to the loss of leaves. Generally, it is not necessary to apply fertilizer to the plants in winter. It is also OK to apply fertilizer once after winter. If you give too much fertilizer, you can pour some water on the plant to dilute the fertilizer or change the soil for the plant

2、 Precautions

In winter, pay attention to put the plants in a sunny and warm place. Don't give too much water. You can stop fertilization
