1. Lack of light: this kind of plant has weak resistance to cold. In winter, if you don't put it in a sunny place, the leaves of the plant are easy to fall off, so you should put it in a sunny and warm place in winter. If the leaves have fallen, you can also transfer them to a sunny place, so that the plant will grow new leaves.
2. The temperature is too low: in winter, due to the relatively low temperature, the ability of plants to resist the cold is somewhat poor, so it is easier to freeze the plants without attention. In this way, the root of the plant can no longer absorb nutrients for the growth of the leaves of the plant, so there will be the phenomenon of leaves falling. At this time, put the plant in a plastic shed with a temperature of more than 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 moist 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 plant to lose life. In winter, when the pot soil of plants is dry, water them again.
4. Excessive fertilization: this kind of plant has a high demand for fertilizer, but excessive fertilization may also cause the leaves of the plant to fall off. In winter, it is not necessary to apply fertilizer to plants. It is also OK to give fertilizer once after entering winter. If there is too much fertilizer, you can water the plant to dilute the fertilizer or change the soil.
In winter, pay attention to put the plant in a sunny and warm place, do not give too much water, you can stop fertilizing
