Last Updated: 2024/11/24, When this happens, the most likely thing is the disease, specifically, "leaf spot". Therefore, in addition to dispose of the diseased leaves, but also spray. Another reason is that because of poor ventilation and poor light, some harmful bacteria will produce mildew. Then, ventilation and adequate light are very necessary. Another reason is that there is too much water and the phenomenon of stagnant water is too serious. In that case, the corresponding is to regulate and control the amount of water, timely drainage.

When you get sick, there will be some black spots on the leaves, which look like black spots from a distance. If it is allowed to develop, it will be more than just a black spot. The dot will get bigger and bigger and eventually become a big piece.

(2) solution: if it is caused by this disease, the leaves that have already developed black spots need to be cut off first and then disposed of centrally. In this way, they can be prevented from infecting other leaves. Then, you need to spray some medicine, such as carbendazim solution.

If the ventilation is not good, coupled with poor light, it will eventually lead to its ability to prevent is very weak. In that case, some harmful fungi will become moldy. Next, black spots will grow on the leaves of the plant.

(2) solution: if the plant is indoors, then be sure to timely ventilation, provide fresh air. If the light is not good, then you must remember to take it out to bask in more.

3. Water problem

(1) specific reasons: it is mainly due to excessive water and stagnant water in the basin, which will also cause the same problem.
