1、 Watering too much

Its leaves are plump, and its underground stems are also rich in water, which is drought resistant. Do not water too often or too much during the maintenance period, otherwise the plant cannot absorb it. After a long time, it is easy to accumulate water, which will affect the root respiration, and the branches and leaves will turn black. Stop water treatment as soon as possible and move it to a well ventilated place. After the water is dried and the plant is restored, reduce the watering times. It is best to see dry and see wet

2、 The light is too strong

Although it is a sun loving plant, it cannot be exposed to direct light outdoors for a long time. A long time will affect metabolism, and the leaves will slowly turn yellow and black. The yellow leaves should be cut off as soon as possible and moved to a place with relatively soft light for management. Avoid strong light in time and do not expose to the sun

3、 Temperature discomfort

It likes warm environment, and has certain high temperature resistance, not cold resistance. If the temperature is not controlled in time in the low-temperature environment in winter, the plant is easy to be frostbitten, which will show the phenomenon of yellow leaves and black leaves. It should be moved to a warm place after cooling. It is best to control the temperature above 10 degrees so that it will not be frostbitten and can live through the winter safely and grow normally

4、 Infected insects

During the management period, if the environment provided is not suitable, the plant is easy to be infected with insects, and the leaves will turn black at that time. The branches and leaves infected with pests should be cut off as soon as possible to avoid further infection. And spray insecticides to completely sterilize. If the soil is infected, it is recommended to remove the basin and replace the soil as soon as possible
