    There are several coloured wood chip mulches on the market.

    Are the pigments used to colour wood chips of concern to plants, and possibly the environment?

    I have seen many suppliers offering various colours of pigment enhanced wood chips. Upon asking about the pigment, all I hear is that the colour added is harmless- meaning the seller has no idea what substance is being used to enhance or change the colour.

    Can anybody enlighten me on this subject.
