What to Do When Rose Roots Turn Black
When rose roots turn black, it is necessary to剪除 (cut off) all the blackened roots promptly and then disinfect them with carbendazim. Improper soil can cause the roots to turn black, so it is also necessary to replace the soil with a loose, breathable, well-draining, and organically rich slightly acidic soil. Afterward, it is important to water and fertilize the plant appropriately.
1. -- Pruning and Disinfection --
When rose roots turn black, it indicates that the roots are infected with pathogens and have started to rot. You need to use a sharp, disinfected pair of scissors to cut off all the blackened roots cleanly. Then, place the plant's roots in a carbendazim solution for disinfection, and finally, put the plant in a well-ventilated area to dry off the surface moisture.
2. -- Replacing New Soil --
The blackening of rose roots may be caused by unsuitable soil, so it is necessary to replace the soil with a new one promptly. The new soil should be loose, breathable, well-draining, and rich in organic matter, slightly acidic, and the soil should be disinfected before use.
3. -- Appropriate Watering and Fertilizing --
The blackening of rose roots may also be caused by improper watering and fertilizing.
