Because it gets so hot here can I grown worms in a bin in my backyard. I have a young garden, 1 yr. old. I have added a lot of various organic ammendments and as of yet I have not seen a single worm. I even purchased some from WalMart but after two days they were gone even though I had plenty of kitchen scraps in the ground. Now I would like to grow some in a bin, confined, but I don't want them to roast in the bin when it gets hot here. Any advice will be appreciated. Thanks
