Far be it for me to come to the add of TruBrown and defend and although I think they took it a tad to far. They were probably following the instructions that were on the fertilizer bags. I tell my clients to not mow for 48 hours on liquids and 24 for granular. Probably TruBrown has gotten sued so many times that they try and let me emphasis try to do things by the books. I know being in the fert business I can't tell you how many times people blame me for everything wrong in the yard.
