Consider this a post mortem, alas there will be no sequel at least for this plant.
It's basically a drying stick with green tomatoes on it. Its death was dramatically fast (days).
After thinking about all the ways I could have caused it (here), I realize now that, not only did I not do anything much wrong, I was missing the obvious one to point the finger at: Home Depot. The one thing I didn't have control over was the soil the plant was planted in and the Southern Blight could have easily slipped in that way (ok I didn't control the seed or it's initial "upbringing" (if you will) either or what it was fed which come to think of it if you're growing something to eat is very much a concern.)
This time I didn't grow plants from seed (actually only have done that once - quite rewarding, but takes more time). Usually when I buy started plants it's from a local nursery who gets them from local growers. This time I was at Home Depot anyway so I decided to try their tomatoes and basil. So far we're 3 for 4. I made the mistake of tossing the tag so I don't know where the plants came from. I know that Home Depot would replace the plant if I asked them to but after thinking about it for about a second I decided no thanks. I don't want to bring in any more "gifts" from them. I'm just glad they're in a planter and not in the soil.
So my local nurseries (Encinal Nursery, East Bay Nursery, Grand Lake Nursery, also Thompson's and Berkeley Hort though I've never bought tomatoes there) will be happy to know that I'll be back and am very sorry I strayed.
So now it's what to do with green tomatoes besides frying them. IF I want to eat them at all as Southern Blight eventually affects the tomato as well. I'm keeping a careful eye on the other plant which while not sick is not looking spectacular either.
