Going on 2 weeks later, seemingly frozen-out tomato plant stems sprouting leaves.
Last frost date for me is roughly the 5th of May. I watched the 15 day forecast... all nights were going to be over 40.
So I set out my plants...expecting there could be a frost pop-up but ready to cover up the plants and expecting things to go ok.
A week later we got hit with the coldest overnight for that date in over 120 years. Covering up the plants didn't protect them from 7 hours below freezing that reached down to 24F.
It looked bad. Really bad, when they thawed. All the foliage collapsed. Little yellowing sticks was what remained.
But, not having put all my seedlings out, we had the option of replanting, which we did, But I told the SO -not- to pull out the damaged remains, because you just never know, plants can surprise you...
And they came through.
Two days ago I noticed little green buds forming along most of the stems. Today 8 of 9 of the very frost bitten stems have perfect little leaves popping out.
