So, I plan to make a few very large boxes with hinged tops out of hardware cloth and therein store the pumpkins, turnips, potatoes, etc. from the garden and next year, when the garden produce is ready to be taken inside, it will have a safe haven. I don't know why I didn't think of it before. The only thing is, food touching the sides of the hardware cloth could be chewed, so perhaps the wire should still be lined with wood. I will think about this just a little more before constructing something for next year. The root cellar can house glass jars and stainless canisters, plus the hardware cloth enclosed boxes full of produce. Yay! I cannot wait.
