Growing roses in your garden is one of the most fulfilling experiences for any homeowner. Witnessing the beauty of blooming roses and their sweet fragrance can be a heavenly experience. However, your rose plants may fall prey to various diseases, and one such problem is Downy Mildew Roses. This disease is a fungus-like pathogen that affects your rose plants, causing significant damage if not treated promptly.

What is Downy Mildew Roses?

Downy mildew is a fungal disease that affects roses, causing yellow spots on top of the leaves with a dense growth of white or grayish-blue mold below the foliage. The disease mainly targets young leaves, buds, and stem tissues, causing them to turn yellow, die, and even drop off eventually. It thrives in humid and moist environments, making it a common problem during rainy seasons or when watering your plants excessively.

The disease spreads via air currents and splashing water, meaning it can infect neighboring plants easily, leading to significant losses in your garden.

Formation of yellow spots on top of leaves
