I have a bunch of it. Online all I seem to see is to keep cropping it so that the tubers eventually run out. How does Roundup work on this? I cant spend all day cropping it.
Roundup is not effective without multiple applications. There are several other products specific to nutsedge that offer much better control, one of which is SedgeHammer.
Here is a link that might be useful: SedgeHammer
Thanks, I will get it and start in the application cycle (since the nutsedge is well established, I will need to go over it multiple times this summer is my guess).
