Peat moss is anti- microbial
Perhaps if I am going to put peat moss or coconut coir (if transporting coir many miles is more environmentally sound) in my garden for my plants then I am not spending money on something for the worm bin if I run either of them through the bin first to get them charged with microbes. But then I read : "Peat moss is anti- microbial the last thing we want to use to help build healthy soils." Well I think I want microbial things happening in my worm bin. Maybe tons of peat moss is anti-microbial but a sprinkling is moisture retaining?
