RoundUp

I'm going to be installing new sod and was wondering if I need to kill old grass with roundup or if just using a tiller would be ok to prepare the area, thanks.

Round up may affect the new sod.

If it's not really weedy with dandelions, you can cut the grass to scalp level
topdress, fix the pH, use a quality starter fertilizer and lay the sod right over top if you like. The old grass decomposes and turns into nitrogen. I do it this way quite often.

For round-up to work properly it must be 70 ferenheit for a few days.
Read the directions and use your safety gear

You can rototill if you like. All of that extra work and raking really turns me off.

The only way I would need to remove the old sod is if it would leave the lawn area too high by laying the new sod over top.

Or, you can just remove the sod a few inches wide around the perimeter, so the new sod
slopes down to sidewalks and stuff...just an example.

Roundup will have no residual affect on new sod- just don't throw it down immediately or anything!

You can lightly till.... I wouldn't go really aggressively because you're just creating more work for yourself (raking it out, re-grading it, etc)

If you scalp it down and spray it off, you'll see where the lows and highs are- you can add some nice screened soil to spread out over the dead turf... fill in where needed and amend the soil a bit with light tilling (like a high rpm tiller, Stihl, Mantis....)

Use Top soil as a top dressing, sorry.

One cubic yard will cover an area approximately one inch deep and
30 feet by 30 feet
for example...
or three inches deep will cover around ten feet by ten feet...

I haven't done sod before, but never realized you could just scalp and topdress before laying sod.

We will be doing a new sod job at the end of May. We will be spaying the existing lawn which is tall fescue with Round Up Pro. If you do the spraying with a few weeks in advance there will be nothing to worry about. You won't hurt the new sod.

Roundup only kills what it touches once its dried its done
But if you want a good kill You need to spray atleast week before you till the lawn for laying sod
