For the most part I've been pleased with Brock. I've been with Brock since for over 32 years, but have to say I wasn't so happy with the "total" kill they did recently. A lot of the torpedo grass on the edges still remained and how hard would it have been to kill the few weeds that appeared on the cracks of the walk-way? Other than that, I hope the lawn treatment being performed on a monthly basis works out as I've brought 3 additional accounts to Brock, and I'd hate for them or myself to be disappointed.
