Garlic often becomes moldy and mushy in the refrigerator. A relative of the onion, garlic is best stored in an open container at room temperatures. Whole bulbs will stay good for months, but will degrade more quickly once opened.
Researchers at the University of California at Davis recommend keeping cukes out of the fridge, as these gourds tend to degrade at temperatures below 50 degrees Fahrenheit. However, refrigerating cucumbers can work well when they're kept clean and dry, wrapped in paper towels, and placed in open plastic bags in the refrigerator's crisper drawer.
