I started an organic garden last year for beneficial insects, bees and butterflies. Everything was going great until powdery mildew took over. We have the ideal climate for mildw were we live.
I made sure the circulation was good around the plants and sprayed them with a milk mixture which didn’t work.
What could I use to kill the mildew but not harm my bees, butterflies, ladybirds etc ?
I heard about using things like baking powder, cider vinegar and neem oil. Are these safe or effective ideas any help would be great!
