Tomatoes past summer dormancy
Hello all! I have a question regarding my tomatoes. This spring we planted several varieties - beefsteak, two San marzanos, a yellow pear heirloom, a grape, and a Mr Stripey - and were rewarded with lots of tomatoes all the way up to August. After that, the plants went dormant, and were mostly turned crispy. Now that it's cooling off again, I went to check on them, and they appear very much alive. The stalks are fully green, and there is new growth on the very ends of the now-long vines.
So my question is this - will these same plants re-flower and fruit for me this fall, or should we start with all new? Someone said on here that Phx tomato season starts with new plants now, baby them thru the winter, and harvest all spring, but has anyone had results with ones that made it through the summer? How long can you keep a tomato plant alive??
