Every day, I dig out at least a couple hundred dandelions. And every morning, I look out and see the yard covered with a couple hundred more of them. Obviously, we were not very vigilant last summer and let too many of them go to seed. I don't want to use weed killer, since the kids are all over the lawn. I am very interested in corn gluten meal, however, a natural weed preventative that can be applied in the spring and fall. Here are some companies that sell it if you're interested, along with the product name. Has anyone used this before?
