Highpoint's fall application of fertilizer and weed control 'browned out' my entire lawn. They applied their treatment on Sept 15th. Two days later it started to turn brown. After two weeks, it was completely brown. Nate came out to look when I was not home. He decided the brown lawn was not their fault. He said the browning was due to shade, trees and lack of rain. Meanwhile, all of my neighbors' lawns were, and are still, lush.
Even after I made multiple calls and sent photos for them to review that clearly showed the damage, they continued billing me. It is now December and I am still dealing with the muddy aftermath. Be warned about this company. Their website boasts of a nonexistent satisfaction guarantee.
