Thanks to those whom have helped me with info over the years. Homeowner reaching out to ask about fertilizer services. I have 140K sq ft, and was using a local service, which was sold to TruGreen. Over the last couple of years, service has been spotty to bad, customer service has been downright lousy. Crabgrass growth has grown, and the local tech's (after 4 calls for service) came out and sprayed - left large brown spots over the lawn that never went away last year. Local replacement options are all telling me that their chemicals are better, more effective, and that services are top notch. All have references, but I can give away free service for references all day long. Very difficult to select someone reputable. Most of my neighbors are doing bags of Scotts on their own, but haven't invested in their lawns like I have. Any thoughts on how to sort through the fray?
