1、 The temperature is too low

It likes the warm environment all the year round and is not resistant to cold. The temperature in winter is too low. If the temperature cannot be well controlled, the temperature will be frostbitten and leaves will fall out. It should be moved indoors after cooling, and the temperature should be controlled above 7 degrees. It should also be noted that it should not be placed too close to the heating equipment, otherwise the leaves are easy to be roasted and fall off

2、 Watering too much

In winter, its growth rate is relatively slow, its water demand becomes less, and its water evaporation is also slow in low temperature environment. If it is watered frequently, it is difficult to absorb it. After a long time, it will Rett roots, and the leaves are easy to turn yellow and fall. The watering frequency should be reduced. If the temperature can be well controlled, sprinkle water around the plant frequently to improve the humidity

3、 Improper fertilization

The growth rate is slow in winter. Usually, the nutrients contained in the soil are enough for the winter, and there is no need to fertilize again. Applying fertilizer is difficult to absorb, but it is easy to burn roots after a long time, and the leaves will turn yellow and fall slowly. Stop fertilizer treatment, loosen the soil frequently, and water appropriately to dilute the fertilizer

4、 Lack of light

It likes a semi cloudy environment. The light in winter is very soft. It should be placed in a place with light. More exposure to the sun can not only improve the temperature of the plant itself, but also promote it to accumulate more nutrients, which is beneficial to the winter. If placed in the shade, the leaves will slowly turn yellow and fall over time
