Using old carpet as a weed mat
I have some old carpet with felt underlay that I'm going to use as a weed
mat rather than newspaper. It looks like an old berber and as best as I can
tell is wool not synthetic. There was plenty of dust underneath it when I
pulled it up so I expect it would let water through OK. Does anybody have
any cautions or can see any reason why I shouldn't use it on the garden?
