The "official" reports showed the low of only -1 C last night (Oct 29/30) here in Bloomington, Indiana, but that was enough to put the end to the growing season for the warm-weather crops. Tomato plants are dead all over town. Morning glory and basil mostly did not survive this either.
About time, I guess...
Some of our pepper plants, surprisingly, are still more or less alive. Perhaps, planting them on a slope helped a bit; also, the plants were somewhat sheltered from above by bean vines on the fence.
Now - as it so often the case - the forecast is for a few much warmer days. But that will only be of interest to cabbages, radishes and such.
