Best for Long Storage
Produce that keeps well at room temperature or in the fridge — great for planning ahead
A good rule for storing vegetables is to mimic their growing environment — store daikon and green onions upright for longer shelf life. When placing them in the vegetable crisper, wrapping in newspaper or paper towels before putting in a plastic bag maintains appropriate humidity and prevents drying. If you can't use everything in time, cutting into convenient sizes while fresh and freezing is the most reliable method.

Frequently Asked Questions
Which vegetable lasts longest at room temperature?
Onions keep 2+ months in a cool, dark, ventilated spot. Whole kabocha lasts 1–2 months, and sweet potatoes 1–2 months.
Which vegetables should not be frozen?
Lettuce, cucumbers, and daikon have high water content and lose their texture when frozen. Daikon can be grated and then frozen as a workaround.
What is the most important rule for storing vegetables?
Three basics: prevent drying, store at appropriate temperatures, and separate ethylene-producing items (like apples) from other produce.
