My PIA centipede turf

It has been an elating experience. The simplicity of your product, meaning it’s application, and the incredible results are just short of amazing. Kudos to you John and Bob and also Chip. Your product and the NC extension office have returned my lawn from a commercial product disaster to a lawn to be proud of owning. Thanks
