What's the best way to reseed after using Roundup?

So most of the grass is dead after a RoundUp/24D confusion, there is still a few live blades underneath, what do you do? Thinking about hydroseeding, thatching, aerating, mowing, don't know what to do to get the seeds down to the dirt so they can germinate.

roundup is inert after you spray it. Meaning, it has no residual/soil activity.

water the area, top dress with good soil (not topsoil junk), throw seed down, throw more good soil on top, water until germinated. In that order.

It's close to an acre so that would be a lot of soil to bring in, I guess what I'm asking is can I just throw seed onto the lawn after cutting it really short and dethatching maybe to help the seed get to the soil (all the dead grass is still there). Is the grass, around it enough to protect it until it germinates or do you have to put something over it?

In that case, re-seed 4x the recommended app rate, then irrigate/wait for rain.

And apologize to customer!

I don't have much personal experience. I suggest mow it and bag the clippings. Then mow it again as short as you can--say a half-inch.
If possible remove the old sod with a sod-cutter--BUT--if that is not possible. I suggest power-rake until soil is 90 percent exposed. Add starter fertilizer and sow seed. Drag to work it in. Apply double the usual amount of seed to allow for some not germinating. Use plenty--seed is cheaper than labor. Use a rye/blue mix.

If not irrigated, install temporary battery operated sprinkler timers.

Thanks, guess I'll mow, power rake, then fertilize, seed and roll.

I think you could do it any way you want. I do a lot of just what you are talking about and always have great results. I happen to hydroseed it but anything will work, slit seeding, a spin spreader or whatever. I will agree, cut the dead grass short, if there is a lot of thatch dethatching would be good. Don't skimp on the seed. You will be fine.

That's reassuring. I guess it's pretty open-ended, you put the seed on the dirt, water it, and it grows

Growing grass is a lot easier than some of the guys who don't do it often seem to think. Just as you said. If you have dirt, put some grass seed there and keep it moist you will have grass.
