Frequently asked gardening related questions
White powdery patches on rose leaves are the classic symptom of powdery mildew, a very common fungal disease. It can cover leaves, stems, and flower buds. The patches are often accompanied by distorted or curled new growth. This disease is exacerbated by poor air circulation, shade, and inconsistent watering (dry roots, humid air). Management involves pruning for air circulation, consistent watering, and using organic sprays like baking soda or milk solutions. Choosing resistant varieties is key.
