I have a 10 round area where a pine tree was removed. The
'grass' that is in the area is full of creeping charlie and everything
that shouldn't be there; If I spray Round Up on this area,
wait a week or more and then lay down newspaper, cover
the newspaper with topsoil and then sow grass seed, would
this work? I need to find a way to make this a grassy area
without tilling as a result of a spinal injury. Thanks. Rosie
I would skip the Round-up and just put down a thick layer of newspaper.
Water the newspaper and cover with some mulch. Let that sit all summer. In
the fall, remove the covering, and seed the area. New lawns do best in most
areas when planted in the fall anyway.
Wait three weeks. You only have to wait two weeks for the Roundup
that is in the soil to decompose safely. But I would wait an extra
week to see that everything is really dead and that you don't have
to spray Roundup again.
Glysophate (RoundUp) has virtually no effect on seeds, and you can
theoretically spray the weeds and put down grass seed on the same day.
3-4 days should be a more than sufficient wait time. The OP's
original idea seems sound, with the wait time mostly to let the weeds
die completely. Topping with newspaper should prevent the emergence of
new weeds. By the time it decays, the grass will have a good start. Be
sure to use the RoundUp on a calm day, as it *will* kill growing
