ok ... so I've got this lawn. Customer wants a nice prettier green lawn. I would like to do it as organically as possible. I was thinking spray for the dandilion with round-up, put down some compost/topsoil mixture to fill in the holes and ruts, then seed with a contractors blend with some annual rye, tall fescue mixture, and use an organic soil conditioner fertilizer ... maybe something like plant health cares turf builder bag... then seed again in the fall .... anyone got any suggestions? help? advice?
