Reseeding through weeds


I want to overseed my grass in one small area but it has some very stubborn weeds in it that are hard to pull. Can I just put Roundup on those weeds then reseed? How long do I have to wait? Thanks - Cindy -

    On the Roundup website I found two different wait periods: 3 days and 7 days. I’d go with the 7 day wait, which will give the Roundup ample time to be ingested by the weeds. One caveat, make sure you are using regular Roundup (glyphosate) and NOT extended control. This is the perfect time to reseed. Good luck, Cindy.
