1. Disease problem(1) Specific reasons: There is a major disease that can cause this phenomenon, called "leaf spot disease". Friends who have raised plants must have heard of it. This disease is relatively easy to identify. If some spots with particularly dark edges appear on the leaves at first, and then they slowly expand and infect other surrounding plants, then it is generally this disease. (2) Solutions: First, of course, all diseased leaves must be cut off and disposed of properly. Make sure the scissors are disinfected. After that, spray the medicine. Different situations require different types of sprays. If the symptoms are mild, you can spray carbendazim. If the symptoms are very serious, then spray thiophanate-methyl, nothing else will work. Just spray it once every half a month. Pay attention to subsequent maintenance as well. For example, don't make the environment too closed and provide more ventilation. In addition, there should not be too much water. Use liquid fertilizer once or twice a month to increase nutrients in the soil. 2. Environmental maintenance issues(1) Specific reasons: Specifically, there are three main reasons: one is that the following three reasons exist at the same time or one of them is particularly serious. The first is too much water; the second is too strong light; the third is too low temperature. (2) Solution: If you are not sure which part has the problem, you should first observe the surrounding environment to determine which part has the problem, and then make corresponding adjustments. In addition to this, you should also be careful not to get tea, coffee, milk, etc. into the soil, as this can easily breed pests and diseases. |
