I would say it is definitely nutsedge................... I have a yard and every flower bed full of it! I have one bed that I have dug completely up twice trying to remove every single nut from the soil with no luck. I have finally learned that sedgehammer or another product whose name escapes me can kill it - but no one can tell me what it will do to my dayliles. I have thinned the population over the years at times, but never eradicated it. I searched all spring at the box stores for the sedgehammer with no luck, but recently found access to place where I can order it. Not sure whether to spray it this late in the season, or just start on it next spring. I will have to spray my entire yard and then probably try to "paint" each new growth in the beds. Best I can tell it might possibly kill the DLs too if I got it on them.

Unfortunately, last year for the first time ever I also discovered a patch of Johnson grass. Johnson grass will get extremely tall 4-5' if left to its on devices and spreads under ground with runners that resembles cane! I attempted to dig that entire area up last year because "it was just a small plot of it" and this year it is 4 X larger. So, I have recently sprayed it with Arsenal (that can be used to kill cane) and that didn't seem to completely get it and since that was all the arsenal I had available at the moment, I sprayed it with an additional spraying of strong RU. Not sure if it is going to actually KILL it............. but, I will hit it early in the spring with arsenal if it raises its head again! I had to purchase 2.5 gals of arsenal in order to obtain any of it - and I only used about 1/2 cup to kill the cane in half of my son's yard. I still have to get the other half done, so I have left the arsenal and his house and just brought home a small amount in a spray bottle to use on the Johnson grass.

I have fought the nutsedge battle for several years without knowing their was something that would kill it - RU only partially kills it......... so my suggestion would be to try to find some sedge killer and have it on hand to attempt to win the long term battle. And I have nutsedge ALL in my lawn.........so it didn't come in from a plant - it is just there. My soil is very sandy which apparently it likes.
