Grass like weed in my flower bed

last modified: 6 years ago



I live in Tulsa. I have grass like weed in my flower bed and it has deep roots and it is multiplying. How do I get rid of it? Thanks

    It reminds me of monkey grass.

    Thanks, any way to get rid of it?

    I have this grown near hydrange and hosta plants. Could the ortho nutsedge killer could destroy them?

    I do not know. I’d shield them with some cardboard or something. I sprayed it around my Oregano and it did not hurt it, but Hostas are more tender.

    If you buy one of the nutsedge-oriented herbicides like Image or Sedgehammer, just read the label before you buy it. Somewhere in the fine print, it should tell you which plants it should or should not be used around. If you have nutsedge around plants that the herbicide would harm, just cover those plants well with a tarp or sheet plastic to protect them while you're spraying the nutsedge.

    Has anyone tried using horticultural vinegar on nutsedge? I’m tired of digging and I hear that works.

    I didn't bother with horticultural vinegar but suspect it wouldn't work. It probably would brown out the green foliage and you'd think it would appear dead, but then the plant would come roaring back, just like nutsedge comes back when people "pull it" out of their lawn or beds because pulling it tends to break off the plant from the nutlet, and as long as the nutlet remains underground, the plant comes back. When I dug ours out of our veggie garden (it took me years to get it all!), I usually had to dig down 6 to 10" to find the actual nutlet and dig it out. I took no chances with these, so didn't throw them on the compost pile for fear they'd survive. I bagged them up in the household trash and disposed of them that way. Image and Sedgehammer both will kill nut sedge eventually, but you may have to do multiple applications several weeks apart.

    I was able to pull someout but still doesn’t see any nut on the bottom. Very long roots.

    I couldn't find the nuts until I dug down 8-10-12", which was an incredibly slow, laborious process in our dense clay soil. I broke a lot of shovels and trowels in our early years here. I often would find a lot of roots about 4-6" down beneath the plant, then just a couple of long skinny roots that went much deeper, and those were the ones connected to the nutlets. Once I was 12 or so inches down, I found long, skinny, horizontal roots running from one underground nutlet to another. Sometimes I'd follow the horizontal root for several feet before finding the plant it ultimately was connected to. It was just crazy. At that point, at least I thoroughly understand why it is so hard to get rid of nut sedge in a garden by digging. I suspect most people never dig deeply enough to find the nutlets. Of course, if you have nut sedge in a yard, you're going to have to use Image or Sedgehammer or something similar to kill it there because no one is going to dig up their whole lawn. Fortunately, I was only dealing with in in the fenced-in vegetable garden area. I am organic 99% of the time, but if I had to go back 20 years and deal with the nut sedge all over again, I'd buy Image or Sedgehammer in a heartbeat and use it because I spent too much time digging it out. I wonder now what I was thinking!
