OK. I'm in Chicagoland and none of the regular Joe places sell stuff that works. Namely on weeds and more specifically on clover or violet. I understand that these are tough to kill and I, of course have no license but this is my own yard. I bought some speedzone at a local Farm & Fleet 2 yrs ago got most of the clover, but I probably hit the violet at the wrong time of year. They no longer have it and mine is gone. This stuff drives me crazy. I see posts on speedzone, quicksilver, drive(?), and coolpower. Can a non-licensed homeowner buy this stuff on a consumer level and where? If not, what is the best that I can do? Thanks.
