Powdery mildew is a foliage disease, which occurs on virtually all species of ornamental plants. Rose, oak, hawthorn, lilac, sycamore, laurel, and crabapple are commonly affected.

Powdery mildew may occur at any time during the growing season; however, it is usually most severe in the late summer months.
