I have a customer who wants his lawn detatched, aerated and overseeded. There are bald spots that need to be top-dressed and then spot seeded but he also wants the whole lawn overseeded. I know fall would probably be a better time for all this but he wants it this spring(soon). I plan on dethatching first, aerating second, then topdressing entire lawn very lightly but heavier in bald spots, and finally spreading the seed with a broadcast spreader. I normally just do a lot of cutting but I'm trying to get into more of this stuff so I'm just looking for some opinions/advice on my plan. Can I do this all in one day or should I leave time between steps and if so how much? Also, is it OK to spread a thin layer of soil over entire lawn after aerating but before overseeding, this will fill in holes made by aerator a bit but would also give a bit better seed to soil contact for germination. Anyones opinion is greatly appreciated, thanks.
