What kind of soil amendments help with powdery mildew prevention?
I’ve been experimenting with different soil amendments in my garden, especially since dealing with powdery mildew. I’ve added some compost and organic fertilizers, but I wonder if there are specific types that might help improve resistance to mildew. I grow a mix of herbs and flowers, and I want my soil to be as healthy as possible to avoid this issue. Anyone have insights on amendments or practices that worked for them?
