Requirements for Long-Term Vegetable and Fruit Storage

This is a list from a great root cellaring book I've owner for nearly 30 years. It was written by Mike and Nancy Bubel, and Rodale published it in 1979. A newer edition is still available in paperback (and I highly recommend this book). The information below is from my copy and provided here for educational purposes only, which the copyright law allows.

The Bubels cover many, many good ideas in their book from designs and personal observations to timely planting, harvesting, and which varieties store best. This list below is the general storage requirements for some vegetables and fruits.
