1. Causes of white spotsThe rose leaves have white spots, which may be because the place where it is usually kept is too humid and not ventilated enough. Pathogens can easily breed in such an environment, infecting the plants and causing diseases such as powdery mildew and leaf spot. When it becomes sick, obvious white spots or white powder will appear on its leaves. 2. Treatment methods1. Pruning: After discovering that it is sick, prepare a pair of scissors and cut off all the leaves with white spots. If there are any branches that have become dry, they also need to be cut off. After that, take it out of the original pot, remove the soil on the roots, and cut off the roots that have rotted or blackened. 2. Disinfection and replanting: After cutting, apply some sterilization liquid on all the cut ends to prevent it from being infected by bacteria. Then, make some new flower soil using leaf mold, fine sand, and garden soil, and plant it in that. This can prevent the remaining pathogens in the old soil from infecting the plants again. After that, put it in a warm place with good ventilation and spray it with fungicide every 3-5 days. You will be able to recover soon. |
