Magic Milk for Powdery Mildew
You know … the unattractive white powdery-looking spots that seem to appear from nowhere during mid- to late-summer? These fungal spots begin on lower leaves and can quickly spread to cover leaf surfaces of entire plants. Lilacs, phlox, bee balm, asters, dahlias, cucumber and summer squash are all susceptible, particularly if the plants do not have good air circulation (a problem I plant to avoid). Not liking to spray fungicides, I've tolerated powdery mildew for years. But when cleaning up paperwork this past winter, I found a note I had jotted down, likely while watching any one of gardening shows I try to take in during cold weather months. The note said: powdery mildew; 1 part milk to 9 parts water; spray 2x weekly.
