Q.nut sedge or nut grass eradication

Zone Hot Springs, AR zone 7b | rosestwome added on September 21, 2017 | Answered

I garden organically and have an invasion of nut grass in three of my gardens and a lawn area. I have dug out the soil and sifted it but a few days later it’s back worse. How do I get rid of this?

Unfortunately, the only recommended method for controlling this grass is what you are already doing.

The only other thing I would suggest is that you lay a black tarp over the area for a few months. Then when everything is dead under, you can uncover, and re-seed with the grass of your choice.
