1, the light is too strong: it is afraid of strong light, if it is placed in the hot sun, the plant will be sunburned, there is a phenomenon of black leaves.It should be removed in time and sprinkled frequently to cool down, so that it will recover slowly.
2. Water accumulation in the soil: If you water too often or too much at a time, the plant cannot absorb all of it. If you water it for a long time, it will accumulate water. In this way, it will hinder the respiration of the root system. The root will rot. It cannot provide water and nutrients for the leaves. It will show yellow leaves and black leaves.It should be drained and ventilated to allow water to evaporate.If necessary, it is recommended to take off the pots, cut off the rotten roots and plant them again.
3. Soil hardening: soil should be changed frequently during the management period, and the permeability of the soil should be ensured.If the hardening is serious and can not breathe, the leaves will be blackened and yellowed in the long run, and the whole plant will wilt.
Its soft leaves may be the temperature is not suitable, the temperature is too high or too low, should control the temperature, or move to the appropriate temperature, the best temperature between 20-25 degrees, so as to facilitate recovery.It may also be that the soil is not suitable, the permeability is poor, affecting the root system, it is recommended to loosen the soil more at ordinary times, and change the soil directly when it is serious.In addition, it may also be caused by too strong light, should be moved to a semi-cloudy place as soon as possible, but also frequently spray water to cool down.
