This my first full year in the lawncare bussiness. I have a couple of custumers that are complaining about excess thatch in there yard after we cut. Most of our customers we don't bag the grass. We recomend to everyone that we at least bag it for the first cut. A few of the ones who still don't want it bagged still complain about the excess thatch, and sometimes yellow grass after we cut. We are cutting at 2.5", is that to low? We have strongly suggested to our customers that they water their lawns more often, we tell them everyday hoping they will do it at least every other day. What should I do?
