How to Keep Vegetables Fresh in Your Refrigerator

Store vegetables in the right zone and humidity level

Most vegetables last longest in the crisper drawer, which maintains higher humidity than the rest of your fridge. This drawer traps moisture that would otherwise escape into the air, slowing the wilting and decay that happens when vegetables dry out. Your refrigerator likely has two crisper drawers—one labeled for high humidity (usually the lower one) and one for low humidity.

High-humidity drawers are for vegetables that wilt easily: leafy greens, broccoli, cabbage, carrots, celery, cucumbers, peppers, and zucchini. Low-humidity drawers are for fruits and vegetables that rot quickly when too wet: apples, berries, and tomatoes (if you must refrigerate them). If your crisper has a humidity slider, push it toward the closed position for high humidity and toward the open position for low humidity. The slider controls how much moisture the drawer releases.

If your refrigerator has only one crisper or the sliders are missing, store high-humidity vegetables in sealed plastic bags or containers on the shelf just above the crisper. The goal is to keep moisture around the vegetables without letting them sit in pooled water, which causes rot.

Key Takeaways

• Store most vegetables in the crisper drawer on high humidity, which slows wilting by keeping moisture around the food.
• Wash vegetables only right before eating them, because excess moisture on the surface speeds decay and mold growth.
• Keep ethylene-producing fruits (apples, avocados, tomatoes) away from leafy greens and cruciferous vegetables, which wilt faster when exposed to ethylene gas.
• Store root vegetables (carrots, beets, potatoes) in a sealed bag in the crisper to prevent them from drying out, and keep them separate from fruits.
• Check the crisper every three to four days and remove any vegetables showing soft spots or slime, which signals mold or bacterial growth spreading to nearby items.

Wash vegetables at the right time to prevent mold and slime

Wash vegetables immediately before you eat or cook them, not when you bring them home. Water on the surface creates an environment where mold spores and bacteria grow faster. A vegetable that sits damp in your crisper for days will develop a slimy coating or fuzzy mold much sooner than one that stays dry until you use it.

The exception is leafy greens sold in bulk (not pre-packaged). Rinse them gently, spin them dry in a salad spinner or pat them with paper towels, and store them in a sealed container or bag lined with a paper towel. The paper towel absorbs excess moisture that would otherwise condense inside the container. Replace the paper towel if it becomes damp.

For all other vegetables—carrots, peppers, broccoli, cucumbers—store them unwashed. The natural waxy coating on the skin slows water loss and protects against mold. Rinsing removes that coating and introduces moisture that speeds decay.

Separate vegetables by ethylene sensitivity to slow ripening and wilting

Ethylene gas is a plant hormone that ripens fruit and triggers vegetables to age faster. Some produce releases a lot of ethylene (apples, avocados, tomatoes, bananas), while other produce is very sensitive to it (leafy greens, broccoli, cabbage, cucumbers). When you store a high-ethylene fruit next to a sensitive vegetable, the vegetable wilts and yellows much faster than it would alone.

Keep ethylene-producing fruits in a separate drawer or on a different shelf from leafy greens and cruciferous vegetables (broccoli, cabbage, cauliflower, Brussels sprouts). If your refrigerator is small and separation is not possible, store ethylene producers in a sealed container so the gas cannot drift to nearby vegetables. Tomatoes, avocados, and bananas are particularly strong ethylene producers—if you have limited space, prioritize keeping these away from greens.

Root vegetables (carrots, beets, potatoes, parsnips) and alliums (onions, garlic) are less sensitive to ethylene, so they can share a drawer with fruits without significant loss of quality.

Store root vegetables and potatoes to prevent sprouting and greening

Carrots, beets, turnips, and parsnips last longest in a sealed plastic bag in the crisper on high humidity. Remove any green tops before storing—the leaves pull moisture from the root and speed decay. A sealed bag keeps the roots from drying out while the crisper's humidity prevents them from shriveling.

Potatoes and onions should not go in the refrigerator at all. Cold temperatures convert the starch in potatoes to sugar, changing their texture and taste. Potatoes also release ethylene gas, which will wilt nearby greens. Store potatoes in a cool, dark, well-ventilated place (a pantry, basement, or paper bag in a cupboard) at around 50°F. Onions need even cooler conditions and should be stored separately from potatoes because potatoes release moisture that causes onions to rot.

If you have already cut a potato or onion, wrap the cut side tightly in plastic wrap and store it in the crisper. Use the cut piece within three to four days.

Organize shelves to prevent cross-contamination and water dripping

Store vegetables on shelves above raw meat, poultry, and seafood. If meat is on a shelf above vegetables, any drips will contaminate the vegetables with bacteria. Meat should always be on the lowest shelf, in a sealed container, so nothing drips onto food below it.

Do not stack vegetables on top of each other in ways that crush them. Bruised or broken skin allows bacteria to enter and decay to spread. If you have limited shelf space, use small containers or dividers to keep vegetables separated and prevent them from pressing against each other.

Check the crisper every three to four days. Remove any vegetables with soft spots, slime, or visible mold immediately—these are signs that decay is spreading. A single rotting vegetable releases ethylene gas and moisture that will speed the decay of nearby items. Discard it rather than trying to salvage it by cutting away the bad part.

Store cut and pre-packaged vegetables correctly to extend their shelf life

Pre-cut vegetables (baby carrots, celery sticks, broccoli florets) come in sealed containers designed to maintain the right humidity. Keep them in their original packaging in the crisper. Once you open the package, transfer any unused portion to an airtight container or resealable bag. These vegetables have more surface area exposed to air, so they dry out and decay faster than whole vegetables—use them within two to three days of opening.

Pre-packaged salad mixes and leafy greens have a printed use-by date based on the packaging and processing method. Store them in the coldest part of your refrigerator (usually the back of the crisper or the shelf just above it) and do not open the bag until you are ready to eat. Once opened, transfer leftovers to an airtight container with a paper towel to absorb condensation. Use within one to two days.

Vegetables you have cut yourself (half a bell pepper, sliced cucumber, chopped broccoli) should be stored in airtight containers in the crisper. The cut surfaces expose the inside of the vegetable to air and bacteria, so these pieces decay faster than whole vegetables. Use cut vegetables within three to four days.

Maintain the right refrigerator temperature and clean the crisper regularly

Your refrigerator should be set to 40°F or below. At this temperature, the growth of most bacteria slows dramatically, and vegetables stay fresh longer. If your fridge is warmer than 40°F, vegetables will wilt, mold, and decay much faster. Check the temperature with a refrigerator thermometer (a simple dial or digital thermometer costs a few dollars and clips to a shelf). If the temperature is too warm, adjust the thermostat dial or digital controls toward the coldest setting.

Clean the crisper drawer every two weeks. Remove all vegetables, wipe down the drawer with a damp cloth, and dry it completely. Mold spores and bacteria can accumulate in the drawer, especially in the corners and along the humidity slider. A clean drawer slows the spread of decay from one vegetable to another. If you notice mold or slime in the drawer, clean it with a solution of one part white vinegar to three parts water, then rinse and dry thoroughly.

Check the rubber seal around the crisper drawer. If it is cracked or loose, cold air will escape and humidity will drop, causing vegetables to wilt faster. A damaged seal usually means the drawer needs to be replaced—contact the refrigerator manufacturer or a repair service for a replacement part.

Frequently Asked Questions

Should I refrigerate tomatoes?

Tomatoes are best stored at room temperature until they are fully ripe, then moved to the refrigerator if you need them to last longer. Cold slows ripening and can make the texture mealy. If you have ripe tomatoes you will not eat for several days, refrigerate them in a low-humidity drawer or on a shelf (not the crisper) to extend their life by a few days. Use them within a week.

Why do my vegetables get slimy even in the crisper?

Slime is a sign of bacterial or mold growth, usually caused by excess moisture or a vegetable that was already decaying when you stored it. Check that your crisper humidity is set correctly—too much moisture speeds slime formation. Remove any vegetables with soft spots or visible mold immediately, and clean the crisper with vinegar solution. Wash and dry the crisper thoroughly before restocking.

How long do vegetables last in the refrigerator?

Leafy greens last three to seven days depending on the type and how they are stored. Broccoli, cabbage, and peppers last one to two weeks. Carrots and root vegetables last three to four weeks. Pre-cut vegetables last two to three days. These timelines assume proper storage in the crisper at 40°F or below and removal of any decaying pieces.

Can I store vegetables in plastic bags from the grocery store?

Thin plastic bags from the produce section are fine for short-term storage (a few days), but they do not seal well enough to maintain humidity long-term. For vegetables you plan to keep for more than a few days, transfer them to a sealed container or a thicker resealable bag. Thicker bags trap moisture better and slow wilting.

What should I do if I notice mold on one vegetable?

Remove the moldy vegetable immediately and discard it. Mold releases spores that spread to nearby vegetables, so do not try to cut away the moldy part and save the rest. Wipe down the crisper drawer with a vinegar solution, dry it completely, and check other vegetables for early signs of mold or soft spots. Mold growth usually means the humidity was too high or the drawer was not cleaned recently.
