(1) specific reason: this kind of plant is more vulnerable to a disease. The disease is called grey mould. It is a fungal disease. It is easy to happen when the temperature is very high and the humidity is also high. At the time of disease, the roots of plants may be infected with some harmful bacteria. Then, the roots are likely to rot.
(2) solution: after rotten roots, you can first cut off rotten roots and deal with them in a centralized way. Next, we need to spray some medicaments, such as paracetamol or metalaxyl. Try to spray chemicals in time to prevent and control as early as possible. In addition, the later management is also very important. For example, avoid watering in cloudy or rainy days. Strengthen the operation of ventilation and moisture removal. In addition, the type of fertilizer also needs attention. You can't just apply fertilizer with n. In contrast, apply more P, K containing two elements of fertilizer.
(1) specific reason: the root grows in the flower soil. Therefore, the soil has a huge impact on the root. If the soil is too sticky and heavy, the drainage and air permeability will be poor. Then, there is likely to be rotten roots.
(2) solutions: first of all, like the above situation, we have to deal with rotten roots first. Next, we need to change its pot soil. Choose the flower soil that can keep fertilizer and has good aeration. We can add some particulate matter. For example, increase the content of some particles such as perlite. The permeability of basin soil can be improved by adding them. In this way, the root system can breathe smoothly, and it will not be immersed in water for a long time. Slowly, the phenomenon of rotten roots may appear less.
