I'm being asked to top-dress a lot of lawns right now that are damaged 1/4 dead. I am in most cases thatching, aerating, top-dressing and seeding. My question is what to use for my top-dressing. I have available to me: A product called GroCo (suppose to be a good compost type material ) I've put it on good lawns with good results except it's to hot for seed. A GroCo / Top soil mix Or A straight top soil Cost on all three is about $16.00 a yard. I charge $45 a yard to spread it alone????
