What can I do about powdery mildew in my garden?
+8
I have a garden and every year I get powdery mildew. I have tried a few different things with no avail. It eventually takes over the plant and kills the produce. Does anyone have successful tips to prevent it, and or keep it under control since it is a spore?

Hi, I have been an organic commercial grower for years, and use a mixture of 40% milk and 60% water and spray it on from a cheap sprayer I buy in the dollar store. also stops back spot on roses. Milk contains a protein that stops mildew so it does not matter if you use skim, 1%, 2%, or whole milk.
