How to store fruits and vegetables so they last

By The Pantry Pro team · 6 September 2026 · 8 min read

Produce arrives with two decisions attached: where in the kitchen it goes, and what it sits next to. Most kitchens make the first one by volume, on the principle that whatever fits goes in the refrigerator, and never make the second one at all. Both are worth making deliberately. Cold ruins some produce outright, and the bowl of fruit next to the lettuce is giving off a gas that ages it.

There are three places, not two

The UC Davis Postharvest Technology Center sorts produce into three groups, and the middle group is the one most kitchens are missing. Its chart, Storing Fresh Fruits and Vegetables for Better Taste (UC Agriculture and Natural Resources Publication 21590), divides everything into produce that goes straight into the refrigerator, produce that ripens on the counter and then goes in, and produce that never goes in at all.

Where it goes	What goes there
Refrigerator	apples kept more than 7 days, apricots, Asian pears, blackberries, blueberries, cherries, figs, grapes, raspberries, strawberries, cut fruit; artichokes, asparagus, green and lima beans, beets, Belgian endive, broccoli, Brussels sprouts, cabbage, carrots, cauliflower, celery, green onions, leeks, lettuce and other leafy vegetables, mushrooms, peas, radishes, spinach, sprouts, summer squash, sweet corn, cut vegetables, herbs other than basil
Counter until ripe, then the refrigerator	avocados, kiwifruit, nectarines, peaches, pears, plums, plumcots
Room temperature only	apples for the first 7 days, bananas, grapefruit, lemons, limes, mandarins, mangoes, muskmelons, oranges, papayas, persimmons, pineapple, plantain, pomegranates, watermelon; basil standing in water, cucumbers, eggplant, peppers, garlic, dry onions, ginger, jicama, potatoes, pumpkins, sweet potatoes, tomatoes, winter squash

Two notes hang off that last row. Garlic, onions, potatoes and sweet potatoes want a well-ventilated spot in the pantry rather than the open counter, and potatoes need to be kept out of the light so they do not turn green. Cucumbers, eggplant and peppers tolerate one to three days of refrigeration as long as they are used soon after they come out. The middle row has a qualification of its own. Ripening does not have to end on the counter: a Bartlett pear turns yellow, soft and sweet at room temperature, and UC Davis gives it one to three days in the refrigerator afterward without losing taste.

Cold is a treatment, not a default

Household refrigerators run at roughly 38 to 42°F, which is cold enough to injure produce that came from somewhere warm. UC Davis names the damage: bananas develop black skin and never sweeten properly, and sweet potatoes take on off-flavors and cook with a hard core. Watermelon kept longer than three days in the refrigerator loses flavor and deep red color. Tomatoes get the flattest verdict — a pink tomato ripens to better taste and color left out, will not turn red in the cold, and a tomato that is already red loses flavor if it goes in.

Extension services do not all say the same thing here, and the disagreement is informative. Clemson's safe handling factsheet says fruit that will not ripen further after picking — its list includes apples, cherries, grapefruit, grapes, oranges, pineapple, strawberries, tangerines and watermelon — should be refrigerated to increase storage life. UC Davis puts several of those on the counter. Both are right about different things. Cold buys days and warmth buys flavor, so the question is how soon the fruit will be eaten.

Ethylene is why produce spoils in groups

Ripening fruit gives off ethylene, and ethylene ripens whatever is near it. The EPA's household guidance names bananas, apples, pears, stone fruits and avocados as producers and says to keep them away from other produce (EPA, Preventing Wasted Food At Home). Utah State University Extension's postharvest page names apples, cantaloupe, bananas and tomatoes.

What ethylene does to a vegetable is not ripening, it is damage. USU lists the symptoms as leaf spotting, loss of green color, toughness or woodiness, bitterness, yellowing, rapid softening and off-flavors. Penn State Extension gives the two examples any household will recognize, russet spotting on lettuce and yellowing in broccoli, and adds a detail worth keeping: ethylene damage generally does not appear in under 24 hours, and exposures are cumulative (Penn State Extension, Keeping Produce Fresh). A fruit bowl sitting above the crisper drawer works slowly and does not stop.

Aimed on purpose, the same effect is useful. UC Davis's method for ripening fruit in a bowl or paper bag is one ripe apple for every five to seven pieces of fruit, with the caveat that Fuji and Granny Smith produce little ethylene and will not help. Illinois Extension supplies the counter pairing to break up: onions and potatoes do not belong together, because gas from the onions sets the potatoes sprouting.

The crisper drawers control airflow, not humidity

The humidity slider on a crisper drawer does not humidify anything. Iowa State University Extension explains that the setting is how much of the drawer is left open to airflow (Iowa State Extension AnswerLine, Choosing the right crisper drawer). High humidity means the drawer is closed and the moisture the produce gives off stays with it. Low humidity means it is vented.

That gives a rule with a simple test. Anything that wilts goes in the closed drawer; anything that rots goes in the vented one. The EPA sorts leafy greens, carrots, cucumbers and broccoli into high humidity, and most fruit plus the vegetables that tend to rot, such as mushrooms and peppers, into low. Illinois Extension fills in the ends of the range: the lowest setting for citrus, the middle for most everything else.

There is a second reason the vented drawer suits fruit. Iowa State points out that letting air out also lets some ethylene out. UC Davis arrives at the same arrangement from the other direction and states it as an instruction: use one drawer for fruit and one for vegetables, so the fruit's ethylene stays off the vegetables.

Inside the drawer, UC Davis asks for perforated plastic bags rather than bare produce or sealed ones — about twenty pinholes in a medium-size bag, if you are making your own.

Wash later, with two exceptions

The default is to wash produce just before it is prepared, not before it is put away. UC Davis's handling steps are to wash whole fruits and vegetables, melons included, under running water rather than soaking them, scrub anything firm enough to take a brush, and dry with clean paper towels. Soaking is specifically not recommended, because it gives contamination more chance to spread. The EPA names the produce that punishes early washing: berries, cherries and grapes mold faster when they go into the refrigerator wet.

Two things run the other way. Illinois Extension advises washing head lettuce and leafy greens and spinning or patting them dry before refrigerating them, which is the one case where washing first wins. And prewashed bagged produce does not need washing again, though UC Davis says unpackaged prepared salad mixes always do.

Cut produce is a different food for storage purposes. Anything cut, peeled or cooked belongs back in the refrigerator within two hours, and its storage times run in days rather than weeks; those numbers are in how long food really keeps.

The counter and the pantry are not the same place

Counter storage means out of direct sunlight, and it buys a few days rather than weeks. A vented bowl or a perforated bag slows moisture loss. A sealed plastic bag does the opposite of what it looks like it should: UC Davis warns that carbon dioxide builds up and oxygen runs down inside one, which slows ripening and can bring on off-odors and decay.

The pantry group keeps far longer, and its numbers move with temperature more than anything else in this article. Clemson's pantry chart gives onions one to three months at room temperature or below, potatoes one to three months at 45 to 50°F, and sweet potatoes and hard squash one to three months at 60°F — but one week apiece at ordinary room temperature (Clemson HGIC, Food Storage: Pantry). A cool basement or an unheated back room is doing most of the work in those figures, and a warm kitchen is not.

All of it happens at unpacking

Every decision above is made once, while the groceries are still in their bags, and then not revisited. That is the useful part. Sorting a delivery onto three surfaces instead of one costs about a minute, and nothing afterward needs attention. The common failure is not that somebody did not know where tomatoes go. It is that the whole bag went into the refrigerator, because that is where bags go.

The EPA's estimate of what uneaten food costs an American household is in what food waste costs a household; produce is the part of that bill a minute of sorting reaches.
