I didn't mean to. I thought I was setting them up in worm paradise - you know, in the tub where all the food scraps are. This was yesterday, and when I checked them today they were no longer, um, wiggly.
I put them in my plastic tub on the balcony, which is the "second stop" for my scraps. The last time I emptied this tub, just for fun I thought I'd put a scoop of soil at the bottom and fish out some worms from the garden heap and add them to this soil at the bottom of the balcony tub.
My guess, now that I've done some reading (should have done that first - sorry little guys!!) is that the tub was too wet and hot. It's plastic, with a lid, and sits in a sunny corner of the balcony. Mind you, as we're discovering this season, sun does not necessarily mean heat!!! (sigh) It's also usually quite wet as well, since one of the things that I routinely dump in there is the last dregs of cold coffee leftover in my pot.
I think I'm going to try again (the worms are shaking in their boots!), only this time with some kind of bedding. I'll update you on how it turns out.
