When I was a kid, we had an unheated room in the basement that we called the fruit cellar. I didn't realize how unusual it was to have a root cellar in a mid-century ranch home. For the most part, root cellars slowly disappeared from modern American homes after the arrival of electric refrigerators and freezers.
I haven't thought about the long-term storage of vegetables before this year. It's not a big deal at Red Bucket Farm since most of my crops have been canned or frozen. But I can anticipate that a cellar would be useful for storage of squash, potatoes, onions and apples.
A friend simply tosses her crops into a wheelbarrow in the garage, so I've followed her example and set up an old desk and some wooden storage bins in our attached garage. This year it's an experiment to see if the squash and potatoes will survive the coldest part of winter. I'll monitor the temperatures and see if it will be possible to store veggies for several months. This isn't ideal, but it's a simple way to start.
