I will be planting a new lawn this weekend. We have a new construction home and a really weed infested and patchy lawn at the moment. The weeds look like a typw of grass but grow in large circular patches outward. the roots are deep. We have Extremely hard red clay dirt here in Raleigh, NC. I am told that the nutrients are all in the soil but the soil is way too compact. I would like to purchase topsoil and spread it out over the existing weeds, etc. and replant fescue. I am worried that the weeds will come up through the new soil and choke my new seed. My question is. Will the weeds die or thrive with a layer of soil on top of them? How much screened soil do I use? I would appreciate any help. Thanks!

You should definitely spray with Round-Up (glyphosate) to control the noxious grassy weeds; if you do not do so, the weeds will over run your proposed turf area. If you eliminate the bad stuff now, your chances of developing a uniform turf will be much greater. Try not to disturb the area for at least 7 days after applying the glyphosate; once every thing is dead, remove all of the non-living material, grade the soil, till (not too deep), add your soil amendments, irrigate lightly, and then plant your seed.
Good luck

i’m thinking it may be too late for the roundup to be effective- should have been done earlier- check your local temps- it needs to be warm and wet for the roundup to work.
