We had a freeze TUESDAY night, so I lost my tomato plants and probably my cucumbers. :(
I replaced those original tomato plants, adding cherry tomatoes, and might have lost those too because even though I hadn't planted them yet I screwed up and left them outside one night when it got below freezing. So, those along with a NEW batch of tomato plants are now side by side in the dirt. I'm hopeful that two out the three freeze-damaged plants will recover.
