@saltmarsh really wishing you the best of luck with your tomatoes as you wait it out a couple days. I dropped a few extra seeds when I planted and managed to have too many tomato plants when I moved them all to bigger pots. Eight plants in the ground and more than 20 for backup. I'm thinking of tossing a few of the backups in some grow bags as extras for canning if I don't need the backups. The rest will go to some charity that helps feed the homeless and needy when they are a decent size. I will still have some seeds left for next year, even if I end up planting more. But the germination rates probably won't be so good and next year I already planned to grow mostly heirlooms because I like the different tastes and colors.
I'm trying to avoid getting too excited about my plants surviving the frost. But I will be quite relieved if they are still doing well tomorrow. I only have one row cover and to me it seems rather flimsy for protecting anything from the cold. So, I just used the bottom half of a water bottle to cover the other plants that didn't fit under the frost cover.
