Two acres means power equipment so I can tell you what they call for here on fescue fall overseeding. They cut the grass down to two inches. Clean up or bag the clippings. Then they use the core machine to poke holes. Then they use a verticutter to cut grooves. Then they clean up all the loosened thatch. Then they spread seed. Then they verticut the opposite direction. Then they water it up. They use a starter fertilizer. Now this last spring, a church did something a little different. About 3 acres was covered by brick, stone, concrete, metal, wood etc. after a school was demolished and then abandoned by a contractor. The church purchased the area and hired it rough cleaned up and then finished it themselves last winter. This spring a farmer brought in a large tractor and a heavy no till grass seed drill. The kind that CRP farmland is seeded with. He seeded right into the weeds, old grass, and even some rocks. It came up good and they sprayed it with something that burned the grass quite a bit in June. It started to look very poor about a week ago with the heat and no rain for 10 days. Then a bit of rain and it looks pretty good again. My guess is they will overseed it again this fall or spring. Fescue has a hard time here with no irrigation. Old established fescue looks very poor here for about one half of the growing season.
