    Afte installing new mulch, I always put down Snapshot at the rate of 150#'s per acre. I'm getting Nut Sedge sprouting up in various places. I went back with another treatment of Snapshot, but it's still too early to tell if it was effective. Anyone else having this problem? And what are you doing to remedy this situation?

    Same problem here. Since I'm on this particuler property weekly, I spot treat with RU. IT seems like it will never go away.

    Snapshot will not control existing weeds, it only controls germinating weed seeds prior to germination. Since nutsedge usually will grow from existing tubers in the soil snapshot will have no effect on the nutsedge. Spray with roundup or hand pull to control.

    roundup will not control nutsedge. it would take multiple applications before yellowing the plant. by then your client would be upset about seeing the weeds. for post control apply manage. it works extremely well.

    Pulling may help but with the way the roots grow you'll be pulling repeatedly.

    It also grows right through landscape fabric.

    Bam said it,

    I'll repeat it.

    Manage works on nutsedge.

    Good luck,

    Manage is great along with Basagran. Could even get less expensive and use MSMA as long as its in mulch, lol.

    Not sure if Manage can be legally used anywhere except in turf.
    Basagran is another option. 2 apps at the low rate 10-14 da interval. My experience with RoundUp is that it burns the tops ok, but doesn't translocate down to the 'nuts'.

    Nutsedge is on the Pennant pre-emergent label.
