Bark Mulch

Can anyone tell me if I need weed fabric down first if I am thinking of mulching with bark chippings, should I kill any existing weeds first? Cheersimage

    You should weed thoroughly before putting down bark chippings. Especially if you have nettles, docks, dandelions etc. And no, I would not put down membrane first. Is it on a border or path would want to put it? On a slope?

    Do extensive weeding and get rid of everything.  Instead of weed membrane, put down layers and layers of newspaper (at least six sheets thick and well overlapping).  Spray them with a hosepipe as you go, to help hold it all down.  Put your bark chippings down over the newspaper as you go, keeping them at least 4-6 inches thick.  That should set you up for a year or so.. if/when weeds start popping through.. rake back the mulch, weed, put down fresh newspaper, spread the old bark on top and add some new so it stays around 4-6 inches thick.

    Thanks Blue Onion!

    It would be on borders rather than paths, does the mulching effect need attending to every annually?

    I mulch every year. The worms work the stuff down into the soil as it breaks down. 

    If you mulch really deeply you might get away with a second year,but you'll probably find wind blown seed germinating .
