I have the possibility of picking up a new account if I can get rid of the broadleaf. As far as I can tell, there isn't a miracle cure one shot treatment to eliminate this stuff. Obviously the worst case is R&R the lawn. They weren't real crazy about spot killing but I told them that may be what it comes down to. What is my best bet to get rid of all the undesirable broadleaf grass and leave the desirable behind? TIA!
