What to do if the leaves of Kalanchoe turn black

(1) Specific reasons: Disease is the most likely reason. Specifically, "black spot disease" is prone to occur. It is very harmful to the leaves. Its symptoms are quite obvious. When the disease occurs, there will be spots on the leaves, which will first be reddish brown and eventually turn dark black. The blackened area of ​​the leaf will get larger and larger and it will eventually fall off.

(2) Solution: The most important task is to cut off the leaves and branches that have obvious symptoms and dispose of them. To be on the safe side, it's best to burn them all. Afterwards, 50% concentration of carbendazim powder can be used for prevention and control. In subsequent maintenance, special attention should be paid to pruning and ventilation, and the light should be good. Furthermore, the initial seed selection is also very important, and disease-resistant varieties can be selected.

2. Place in a cool place

(1) Specific reasons: The leaves may turn black if the light is too strong or the light exposure time is too long. That is why the leaves get burned.

(2) Solution: Observe the location of the plant to see if the light is too strong. If this is the reason, then you need to change its location to a cooler place.
