Question
I live in southern Ontario Canada. We can know longer use any weed killers, in fact there are none left on the market that will kill weeds in your lawn without killing your grass too. Charlie has just about taken over the entire lawn. Is there anything that works which is a natural product?????

Answer
Apparently you are prohibited from using the conventional weed killer chemicals. I do not know how you personally feel about this; but Borax has been recommended for control in lawns. If you care to learn more about this, here is a site which may help you.
