I used to buy worms from Billy Carter's Worm Farm in Plains, Georgia. Yes, he's Jimmy's brother. Those boys were more than just peanut farmers! I used them to feed my fishes and tossed a few in each container, which made a nice addition to the pots. Now, since it doesn't matter what kind of worms I use, I just dig 'em up. (I'm keeping smaller fishes these days.) They look really ticked off too! We have really big night crawlers in the raised beds, so every time I plant something there, I get a few big, angry worms...and they come after me! (I know this sounds silly, but I'm terrified of worms...blame my brothers!) Fortunately, I love my garden more than I fear the worms that are so good for the garden. heh, heh
