Obviously, those of us at LESCO believe we make a high-quality fertilizer that you should consider for your applications. Although, as Norm Al points out, some of the issues you bring up point to the need for more of an herbicide or a combination fertilizer/herbicide product. We do certainly offer those as well.
Our nearest store to Bristol is in Arden, NC, which I believe is about 75 miles. Given that distance, your best bet may be to look for LESCO products at a nearby Home Depot, as they carry a limited selection of LESCO products as well.
