    This was 24 yards of sand-compost mix for a driving range. It was slit and seeded just before I topdressed.

    Can seed be sown and ...THEN...Roundup applied, an hour after seeding. One big step...seed and kill the old grass. The old grass dies, just as the new grass comes up. Perhaps aeration should be in there somewhere.

    This is probably the only way to tell if aeration before seeding is helpful...if you followed with Roundup you would not have the old grass to interfere with judging the percentage of take of the new grass.

    Keep in mind aeration only makes holes on about 4 percent of the turf; seed falling into the holes does not sound like much to me.

    I hope I have a chance to test this, (again). I don't have an aerator--I have to use my soil probe. I tried last year--but cannot find the link at the moment.

    I have seen this done for roughs and green and tee banks on golf courses. It can be a very smooth transition. I believe they were slit seeded and aerated both. Scalping was one of the steps and I believe aerating was done a few days after Roundup. The plugs were dragged around so the soil that fell off helped bed the seed. My exposure to that was a long time ago but I think the steps were as you described.

    Looks like decent machinery for a job of that size...

    Did you get any shots of the field with the coverage??? Seems like the grass should sprout quite well if the rains come...

    Yeah,I just thought it was far enough off topic as it is since I did not aerate. I have pictures of several places where I have used this process. Most of my equipment, other than mower, is old but works fine.

    So...what is your opinion...will Roundup hurt new seed (ungerminated stage)?

    Why not rent or use a slit seeder if you are seeding a lawn???? Do it correctly.

    Roundup only reacts in green growing plants and becomes inert on soil...

    Unfortunately in my area fall fescue seeding goes hand in hand with core aeration and spreading seed. So selling premium slit seed service isn't much of a option.

    I'm strongly thinking of renting a slit seeder instead of a wb aerator(I own a ride on aerator). I would use the slit seeder for some very small lawns and gated back yards.

    I'm thinking that running the aerator and spreading seed has to be pretty close to slit seed only in smaller areas so labor might be close.

    My thought is that I can get some test plots to show people the difference in the success of germination. I'm also wondering how lawns done both ways will hold up to the heat of summer and brown patch.
