Whats the best/cheapest/natural (3 separate questions or 1?) way to control mildew on plants?
We have a lot of roses that had not been nurtured for years, and they are really struggling with mildew (black, white, yellow, you name it these roses got it).
I'm also getting a small garden started and noticed white mildew showing up on my pumpkin leaves.
Will the same solution work for many different types of plants and mildew, or will I need to trouble shoot each case individually?
