I often wonder if the earth worm is all hype. They are are a non native species, I know that some plants native to southeast are adversely affected by them. I believe that they are responsible for lower organic matter in our soils due to speeding the decomposition of any organic matter. Yes they make readily usable nutrients, but at what price? *I also now understand this is a subset of an actual soapbox.
Red clay loam, 188 frost free days, loamy soil at another site I grow at.
