I have a flat 2.5 acre lot no obstacles. Soil is Very Very compacted sand with no grass and even very few weeds. The owners obviously wants grass there and they do not have any water supply there other than mother nature. What do you recommend for handling this? My thought is to till it all with a tractor and add at least a few dump trucks of top soil maybe 1" worth, and then either hydro-seed or broadcast seed and rake in. I think the things I need to do for sure is break up the hard ground and also add top soil. Any recommendations for this? Also what would be a reasonable price to do this? This is a job a little bit bigger than I'm used to.
