I'm trying to find out more about using red worms in the grow beds (F&D). I've seen several posts mentioning their use. I've seen them called red wrigglers and red worms. I was wondering if they can be bought or found (better) locally and do they survive well during shipping? (I am in Houston, Texas)

I think our search engine said the word "worm" was ignored because it was too common.

Just found this which might be helpful to other seekers:
