This weekend, I finally got a couple of stakes, and transplanted to along the fence in the backyard, using said fence to help support the plants when I ran out of stakes. The poor things looked all droopy from the shock of being transplanted. I hope that transplanting them at this point wasn't a horrendous mistake, and that the fact that they aren't so much in a garden bed as they are in yard doesn't hurt.
I've heard that tomato plants are hardy, and relatively difficult to kill. We'll see if I have a black or a green thumb.
