Neal, they do make an organic Preen, corn gluten. It's just that I though ALL Preen was organic and when I bought some I was shocked to find out it was NOT organic. It was returned and I found they didn't even carry the organic version but surprisingly, I found it at WalMart! It made a huge difference in my garden this year. I struggle to keep up with weeding so I used it in the vegetable garden. I never did get my flower garden weeded. Grass everywhere. And that Johnson grass is pretty close to impossible to get rid of. My son got a propane flame thrower and we used it to try and keep it down.
