I never grow a bunch of root crop veggies cause I don't have a way to store them so they don't ruin , except carrots and they store in the ground where they grew all winter.
What does a person do if they don't have a cellar or a basement?
I came across a bunch of ways to store a large amount of potatoes without a cellar.
This link is one of them. http://www.saveourskills.com/4-simple-root-cellar-ideas
and I love it. I already knew that storing food in the ground is how it was done way back when...but I never gave it much thought until I really wanted to grow lots and lots of food.
I also saw that people were storing food under their house that only has crawl space. My crawl space is 2 ft but I cant see me crawling under there all the time but I would if I had no other choice.
What I haven't found yet is a chart or something that tells you what the temperature should be at certain footage below the ground.
