This spring we subbed out the renovation of a new lawn for one of our more demanding clients. The sub brought in 60 yards of what is now know to be fill to cover an 8,000 sq ft existing lawn. We raised the irrigation heads on the property at a cost of over 1K. The lawn is not growing, and the client is not happy. A recent soil test came back with a CEC of 5.3, (we are still waiting on a full report) What would your course of action be? Remember... the client is very demanding, and simply adding more topsoil is not an option.
