The fundamental reasons for the rose powdery mildew
The fundamental reasons for rose powdery mildew mainly include three points. First, the plant is prone to the disease in warm and humid or dry conditions. Second, improper fertilization, excessive application of nitrogen fertilizer, or calcium and potassium deficiencies in the soil can lead to the disease. If the planted plants are too dense, poor ventilation and light transmission will exacerbate the condition. Third, significant temperature fluctuations and overly dry soil can reduce the plant's resistance to diseases, making it susceptible to infections.
