1、 Lack of light

Its origin is in the tropics, with high requirements for light. If there is no light in the breeding process, photosynthesis cannot be carried out. Over time, the leaves will become dim and fall in serious cases. Most of the old leaves fall, but the new leaves won't fall. If this situation is found, move to a place with good outdoor light as soon as possible, and rotate the flowerpot direction regularly to ensure uniform light reception, so that the treated plants will recover slowly

2、 Insufficient fertilization

It prefers fertilizer. If the plant does not have enough nutrients during the maintenance process, it will lead to poor growth and defoliation. It is recommended to supplement fertilizer every half a month in the peak growth season. The fertilizer should be diluted with compound fertilizer solution. Thin fertilizer should be applied frequently, so as to ensure sufficient nutrients and more prosperous plant growth

3、 Low temperature frostbite

Plants in tropical areas naturally like warm environment and are not resistant to cold. During the maintenance period, we must pay attention to the low temperature in winter, and the temperature must not be lower than 15 degrees, otherwise it is easy to frostbite the plant and shed leaves. After cooling, move it indoors and control the temperature at about 18 degrees

4、 Watering too much

It has a certain drought tolerance. If it is watered frequently during the management period, it is difficult for the plant to absorb all of it. After a long time, it will Rett roots and rot roots. If it cannot provide water and nutrients to the leaves normally, it will naturally yellow leaves and fallen leaves. The amount of water should be reduced. It is recommended to use the method of seeing dry and seeing wet. If the phenomenon of falling leaves is serious, it is necessary to take off the pot and trim the rotten roots and withered roots
