Powdery Mildew

The recipe for the homemade powdery mildew fungus control seems to be working. I combined the water and soda first in a traditional sprayer then added the oil and shook. I sprayed all phlox in Garden 4 (Tuesday, May 30...see pix). I went to check Thursday and Friday and no signs of mildew are showing.

Next spraying will need to be Tuesday, June 13. Missed the deadline and sprayed July 9. Many bottom leaves on phlox dead and shriveled.

Recipe:
Mix 1 tablespoon baking soda with 1 gallon of water in tree sprayer. Add 2 1/2 tablespoons ultra-fine oil spray. Shake and spray.
