How Do I Get Powder Mildew Off of Dried Flowers?

Powdery mildew is a common fungus that grows on the surface of indoor plants, including dried flowers. Although powdery mildew may not be as damaging to dried flowers as it is to living plants, the fungus tarnishes their appearance and may spread to nearby living plants. Powdery mildew, unlike many other damaging fungi, grows well in dry environments and can easily cover bouquets of dried flowers. Removing powdery mildew from delicate dried flowers is a simple process if you have the right supplies and pay careful attention.
