I was putting down layers of newspaper but it was taking too long and not to mention it was a back killer.
Until I had a brainstorm! I went to the local newspaper and got some butt end of rolls for $5 a piece, bought 6.
I unroll about 2 or 3 layers
Then cover with just a light layer of chips,Just enough to cover the paper.
Very few weeds got though that. And the time I save now is priceless, And my back likes it too!
