I need to renovate a lawn that is about 1500 sf, and supposedly was damaged by cinch bugs. Really sparse grass, weeds, and generally not well cared for. My first inclination was to harley rake grade and hydroseed with a rye/fescue mix. Now I am thinking maybe roundup and aerate 4 times , seed and topdress with a light topsoil and compost mix. I am worried about these bugs coming back. I am strictly in the renovation aspect in this job, but I dont want to waste my time or the owners time and money. Any suggestions?
