What Is Powdery Mildew?

Powdery mildew is basically a group of diseases that show up in the form of white powdery coating on stems, leaves and even flowers.

However, it is not a plant killer, but does weaken them and even diminish the effect of photosynthesis. Such things can lead to poor yield, which means your roses may not last the season.

Powdery Mildew is spread by spores carried by the wind onto leaves. The powdery coating favors humid weather, rather than the wet-conditions.

These spores are formed in high-humidity conditions and even disperse when humidity diminishes. There are a number of garden sanitation practices and fungal disease resistant variants that can help you get good control on powdery mildew.
