I know that earthworms love acid. They are commercially grown in coffee grounds. You can buy them packed in them.
Gardeners use baking soda to treat fungus on roses organically. It can't survive in an alkaline environment.
My Dr. told me to take 1 tsp. of baking soda in 8 ozs. of water every morning and every night to fight the parasites, because they don't like alkalinity.
