Weeds In Mulch

    A customer of mine decided to do his own mulch. After he finished, I asked him if he had put any type of pre-emmergent down before installing the mulch. He looked very puzzled:eek: . He then says "Can you do that for me? My wife just hates pulling weeds." Ok, so now the 64k question---Is there anything out there I can put down on top of the mulch to help out with his inevitable weed problem? It looks like the mulch is only about two inches thick at the most. Thanks.

    Take the time to cultivate some Treflan into the mulch the customer put down. That should form a very effective barrier.

    I agree, Treflan. Personally I've never cultivated it into the mulch, just got a little hand spreader and went right over the top.

    If there's any weeds that are already showing, you'll have to remove those first.

    AND in case you're wondering, I get mine at Lesco....

    Gotta read the label.... Preen would work as well, or so I've heard.

    With mulch , you should not need a pre e .
    Use more than one pre e.
    More control .

    Gallery and Barricade sprayed over-the-top will keep weed seeds from germinating for about four months without worry of damaging anything except tulips. It won't control anything that grows from a root, rhizome or stolen though, so you may have to spot treat with Roundup if something breaks through. I do agree with the post that said you won't need pre on new mulch for a whole season unless it is compost with seeds in it then you definately want a pre on top. Neal
