freeze damage in peas
I grow winter peas down here, and have managed to do so successfully for many years. The temperatures get down to 25F or so, and they come through unscathed. This year, it's been colder, and a week or two ago it registered 21F outside. The unprotected peas wilted some, and I thought they were gone. But, as of now, they are growing vigorously, leaving behind some dead leaves on the lower vines. So at 21F, looks like freeze damage is significant, but evidently very survivable. It seems that the leaves are affected before the stems.
Now, I planted these in early December, fully intending to have them done and gone in March to make way for cherry tomatoes on my trellises. But it's been so cold this winter that everything is going a lot slower. It'll be another month, I think. Of course, for the same reason, it's not a good time to put in my cherries, though I usually do that the first week in March.
