    Gentlemen I was wondering if I could overseed my lawn this coming fall O5 with Midnight or Moonlight Kentucky blue grass. I already put down a 50/50 mix Kentucky blue and rye in the fall of 2003(New Lawn). The lawn is doing well but I was hoping to improve it by overseeding Moonlight or Midnight. I read awhile back that the 50/50 mix I put on my lawn in 2003 probably is all perenail because perinial was too agressive for the Kentucky Blue. Is this true? If so why would people from Lesco where I bought the seed recomend 50/50 over a 85/15 KB/PR that I wanted? I would rent a slicer seeder to apply the seed this fall.

    PS. this lawn does get over 6 hrs of sunlight.

    Any advice or help would be appreciated.

    I can't give you any thoughts on the seed, but you might consider over-seeding with a aerator. It sounds like the lawn is in pretty good shape and you are just wanting to thicken it up some more. A slice seeder is good on bare lawns, while a Aerator will do more then just give soil contact. It will loosen soil and allow for nutrients to reach the roots.

    There are a couple of seed blends that work well for our area that were developed at Penn State University.
    For the most part they are combinations of bluegrass, rye and fescues one being for sunny application and the other for shady areas. I have found them as Penn State A and B at local feed supply's. Lesco might have them also but I'm not sure.

    To echo Soupy's reply a fall aeration and then over seeding at about 1#/1000 should help. I would consider a dolomitic or pelleted lime application of 25#/1000 which would be good but you could go as high as 50#/1000. Most soils in western PA are on the acidic side.

    first of all I think you would be happier with aeration do it by the book fall only hold off on mowing for as long as you can. How about a creeping red fescue that blends kentucky blues and ryes real well. cheewings fescues would do good also. My advise is avoid lesco products just my 2 cents.

    I definitly will use the core areation instead of the slice seeding to overseed this fall. I am still leaning toward Midnight. About the lime I have put down close to 15000 pounds of the stuff(first time I applied it we had a major rain storm and my lawn was not it yet. It look white rivers running through my lawn) in the last two years. I did a soil test two years ago and results recomended that I put 200 pounds a 1000 down. I have approximatly little over and acre. I am going to test the lawn again this spring to see where it is at. Hopefully the results should be right on.

    thanks again for the recomendations.
