The million dollar red worm question!
So, I've got my bin going with 2000 worms and everyone is happy and healthy. I'm loving vermicomposting.
So a gentleman that I spoke with prior to starting told me that red worms will not live here in Michigan. I didn't really doubt him, b/c I had read a lot online saying that red worms functioned best (composting & reproducing) at temps between 55-77, but could tolerate 40-80's. Well, as most know temps here in MI dip WAY below freezing often by Halloween. He also told me that not only are the temps way too harsh, but our soil conditions are just not right for them.
So onto tonight... I went to a local chapter garden club meeting on Vermicomposting and the woman giving the talk said she puts the worms into her garden w/ the castings each fall. She does this to improve soil quality and to add worms to her yard.
I guess at this point I'm just confused. I read online tonight that red worms can live 4.5 years in a bin, but only 1 year in the wild. Can someone give me the whole scoop on having red worms in the garden? I use my worms for composting and don't really plan to dump them into my flower beds (tons of earthworms already), but my MIL is interested in starting a bin to bulk up her landscape. And frankly I just need to know the answer to this question!!!!!
