Margaret Roach has been writing about gardening for many years. She has a 2.3-acre garden in Massachusetts and shares helpful info like this VEGETABLE-STORAGE chart from the University of Wisconsin on her blog. Very helpful!
Keeping Vegetables fresh. Fruits and vegetables require about three different levels of relative humidity. Items requiring high relative humidity (90-100%) include leafy greens, beans, cucumber, asparagus, broccoli, celery, avocado, berries, green onions, and pears. A medium relative humidity (80-90%) is best for things like melon, sweet potatoes, tomatoes, and citrus. Low relative humidity (below 80%) works best for dried garlic and onions, pumpkin, and squash."
