The reasons for the rust-red color change in rose leaves
Rose leaves turning rust-red are usually caused by powdery mildew. This is a fungal disease, where infected plant leaves will turn yellow and develop red rust spots, which can lead to leaf drop and the plant drying up. It is usually necessary to control the planting density, with no more than 12 plants per square meter. It is also important to fertilize appropriately to enhance disease resistance. Remove dead branches and fallen leaves promptly and spray with medication after the onset of the disease.
