If you have a full lawn of fescue, zoiysia, centipede, St Augustine or etc you will want to either take your broadcast or seeder spreader, the name of the stuff I forgot but I think its turf builder. KILLS WEEDS, NOT LAWNS. you will see results within maybe 2 weeks or less. or you can do it the old fashioned Way, I take a spading fork and losen the patch and pull up. I do all this for my customers but my yard I could care less, if I didnt have clover and all the other weeds, I would have no yard. I agree with the person saying it keeps it green.
oh oh oh.... I forgot to mention, make sure you catch the clover before it can seed
