1、 Watering too much

The money tree has little demand for water. If it is watered too much, the root of the plant will be flooded, which will inhibit its respiration and is not conducive to the absorption of water and nutrients, which will lead to the blackening of the leaves. The amount of water must be controlled during normal watering. If there is ponding, it needs to be removed in time, loosen the soil properly and strengthen ventilation, so as to evaporate the water as soon as possible

2、 Raise the temperature

Money tree likes a warm environment. In winter, the temperature should be controlled above 10 ℃. If it is lower than 5 ℃, the plant is easy to be frostbitten and make its leaves black. Before winter, move the plant to a warm place indoors in time to avoid frostbite. If the indoor temperature is low, it is necessary to put plastic bags on the upper part of the plant to prevent cold and keep warm

3、 Strong light exposure

Money tree likes light, but it is not resistant to exposure. If it is put under the hot sun for a long time, the leaves of the plant will turn black after being sunburned. It needs to be properly shaded in summer to avoid receiving direct light. Especially at noon, you need to put it in a semi cloudy place and put it back under the sun in the morning and afternoon

4、 Infectious diseases

If money tree suffers from some diseases, its leaves will also turn black, such as brown spot, anthrax and so on. After the plant is sick, the diseased branches and leaves need to be cut off at the first time and sprayed with carbendazim for treatment. Good ventilation should be maintained at ordinary times to reduce the possibility of bacteria breeding. At the same time, appropriate fertilization should be applied to improve the disease resistance of plants
