Ditto on the sand for carrots. I remember my old landlady used the sand for carrots. Each carrot would not be touching another carrot. For some reason I thought the sand might have been damp-ish but that might just have been the normal environment for her root cellar.
Naturally I didn't have a camera with me as I was learning from my landlady but I can remember that there were wooden shelves attached to one wall. On the shelves wooden boxes, this being before plastic become popular/available/affordable.
Once again I will rely on the magic of the internet to show you what my mind's eye can see as I stood in the dark basement with my landlady. Here you go...damp sand, carrots not touching; close enough:
