I’m having great luck with Espoma Organic Weed Preventer I read about in a handyman mag and bought off Amazon. Only issue is it does nothing to clover, my most hated weed. Seems like it does the rest. It does take a few years to build up in your soil, but it’s all natural since it’s just corn gluten. I’d love to find an organic way to kill the clover, but so far all I’ve heard of is vinegar and it seems to kill grass if you use enough to kill clover. Trying to keep it safe fro little kids to roll around in.
