Does Roundup have any residual effects?
Does Roundup have any residual effects to the soil? How soon can you plant something in the same soil you sprayed Roundup in?
Roundup binds to the soil and will not move. You should wait 7 days to let the roundup kill the weeds before you mow or till. I read you should wait 30 days to plant a tomato but most crops you can plant after 3 days.
