(1) specific reason: This is the most likely reason. There is a disease called leaf spot. Looking at its name, we know that it is mainly harmful to the leaves of plants. Yes, after getting this disease, there may be some small black spots on the leaves first. Then, if the disease gets worse, the black spots will get bigger and bigger. Finally, the leaves will wither and fall off.
(2) solutions: first of all, we need to remove the leaves with black spots, which are relatively serious, and deal with them well. This is done so that they do not endanger healthy leaves. Next, we can use some medicaments to help the plants fight against diseases.
(1) specific reason: This is not to say whether the water is excessive or insufficient, but that we accidentally sprinkle water on the leaves when we pour it. In this way, if you are exposed to the sun again, you will form some sunburn. In this way, from a distance, I thought it was some small black spots
(2) solution: as for the leaves with black spots, there is no disease involved, so there is no great harm to keep them. If you think they are inconvenient to watch, you can remove them. In addition, when we water the water, we should pay attention to it and pour it down carefully. In order to achieve the purpose of not splashing on the blade, it can be poured from both sides, not from the top down.
