Safest weed killer for lawns (clover and other weeds)
My main lawn weed appears to be clover. I have a small townhouse yard, but the clover started spreading all over my front yard. I used Round up directly on the infected areas at the beginning of the season and then patch seeded the areas. That worked ok, but I have a new patch of clover and I don't want to go through that trouble again. I have been looking at products like Ortho weed killers that are safe for lawns, but I really would like to use whatever is the safest chemical.
So the question is, what is the safest product I can use on my lawn that won't hurt the grass and will kill a broad range of weeds (expecially clover). I'd like my children to be able to play on the grass a couple of days later without worrying about dangerous residual chemicals.
