This pest grass I believe was transported in from another part of the state with some day lilies.
It comes up in one particular spot and takes over. This year I even dug up this particular spot, transplanted everything in there and sprayed roundup two different times. Then recreated a mound bed with new plants and now this stuff is coming up through the mound! Lots of it! Help!

    Nutsedge is a difficult beast.
    There’s a product called “sledgehammer” that is getting rave reviews…

    There’s this:

    Personally, I’m not a fan of dumping chemicals in my yard and garden… I think I’d try covering the bed with sheet plastic, and then old wall 2 wall carpet, and on top of that… a few inches of woodchips… and then… let it set for a coupla years… put my container garden there…

    I don’t know how long the nutsedge tubers survive without light, I had very good success with rattlesnake weed using plastic and carpet… If you’ve ever done battle with florida betony, you know it can be impossible.

    I’ve been doing some additional research…

    Could this be cogongrass?
    Listed as one of the world’s top ten worst weeds…
