I’ve seen a lot of literature about cold damage to sweet potatoes during storage. That temps below 50 can make the interior hard and inedible.
Does this apply when they are still actively growing in the ground?
My soil temps were fairly warm, but after several nights in the 40s, I’m concerned that at least the upper part of the roots in the ground may in fact have sustained some cold damage. I dug about 75% of my roots last week, but there are still some out there. It was 39°F last night.
Are the roots still ok? Or should they just become conpost?
