Getting rid of powdery mildew
I have a bad case of PM. I have been using the milk mixture every other day with 3 parts milk and 7 parts water. I have heard about copper several times in the forums. Will I see better results? and is that organic? I have also read about neem. Which will give me better results?

The milk works better preventatively or at the first sign of infection. It doesn't work very well against advanced case.
Other things to try are baking soda solution:
baking soda solution:
1 tablespoon of baking soda
½ teaspoon of liquid soap
1 gallon of water
Be sure the soap is soap, not detergent (dishwashing liquid is detergent), which can harm your plants.
Or 3% hydrogen peroxide from drugstore, sprayed straight from the bottle without diluting (test it on a couple leaves first to be sure it doesn't burn your plant).
Alternating different solutions works better than sticking with the same one all the time.
