How to Store Mint in the Refrigerator So It Stays Fresh for Weeks

Store mint upright in a jar of water, like a bouquet, and it will last two to three weeks

Fresh mint wilts fast at room temperature but stays crisp in the refrigerator when you treat it like cut flowers. The stems absorb water, which keeps the leaves firm and green. Place a bunch of mint stems-down in a jar with about an inch of water, cover the leaves loosely with a plastic bag, and set it on a shelf where it won't get crushed. Change the water every few days if it becomes cloudy. This method works better than wrapping mint in paper towels because the leaves stay hydrated instead of drying out.

The plastic bag matters because it traps humidity around the leaves without sealing them so tightly that they rot. A loose drape—not a sealed container—lets air move while keeping the leaves from losing moisture to the dry refrigerator air. If you don't have a jar, a glass or even a coffee mug works. The goal is water contact at the stem end and air circulation around the leaves.

Key Takeaways

  • Mint stored upright in a jar of water lasts two to three weeks, much longer than wrapped or sealed methods.
  • Change the water every few days to prevent bacterial growth and keep stems absorbing moisture.
  • Cover the leaves loosely with a plastic bag to trap humidity without creating a sealed, rotting environment.
  • Store mint on a middle or lower shelf where it won't dry out from warm air and won't get crushed by heavier items.
  • Pinch off leaves from the top as you use them, which encourages the plant to branch and keeps the bunch looking full longer.

Why mint wilts and how water prevents it

Mint leaves are mostly water. When they're cut from the plant, they begin to lose that water to the air through tiny pores in the leaf surface called stomata. At room temperature, this happens quickly—leaves go limp within a day or two. Cold air in the refrigerator slows this water loss dramatically, but the leaves still need a source of water to replace what they lose.

Storing mint in water solves this problem because the cut stems act like a straw. The plant tissue pulls water up from the jar into the leaves, keeping them plump and crisp. This is the same reason a florist puts cut flowers in water. Without water contact, even refrigerated mint will wilt within a week because the leaves are still losing moisture faster than the dry stems can replace it.

The right container and water setup

Any container that holds water and is tall enough for mint stems works—a drinking glass, mason jar, coffee mug, or even a small vase. The container should be deep enough that stems sit in about an inch of water. Mint stems are soft and don't need a heavy vessel; a lightweight glass is fine.

Fill the jar with room-temperature tap water. There's no need for special water or additives. Change the water every two to four days, or sooner if it becomes cloudy or develops an odor. Cloudy water means bacteria are growing, which can clog the stem and stop water uptake. Fresh water keeps the stems open and the leaves hydrated.

If you're storing a large bunch, you can divide it into two smaller jars so the stems aren't packed too tightly. Crowded stems can trap moisture and create pockets where mold grows. Spacing them out improves air circulation and extends shelf life.

Using a plastic bag to hold humidity without trapping rot

Once the mint is in water, drape a loose plastic bag over the leaves—a grocery bag, produce bag, or even a piece of plastic wrap works. The bag should cover the leaves but not seal around the jar. You want air to move in and out; the bag's job is to slow water loss from the leaves, not to create an airtight seal.

A sealed container around mint causes condensation to pool on the leaves, which leads to mold and rot within days. The loose drape is the middle ground: it reduces the dry air hitting the leaves while letting moisture and air circulate. If you notice water droplets pooling on the inside of the bag, loosen it further or remove it for a few hours to let the leaves dry.

Where to place mint in your refrigerator

Store the jar on a middle or lower shelf, away from the back wall where cold air blows directly. The coldest spots in a refrigerator are near the back and bottom; mint doesn't need that extreme cold and can actually suffer if it freezes. A middle shelf in the main compartment (not the door) keeps mint at a steady, moderate cold that slows wilting without damaging the leaves.

Keep the jar away from ethylene-producing fruits like apples, pears, and bananas. Ethylene is a gas that ripens fruit and speeds up wilting in herbs. If your refrigerator has a dedicated herb or vegetable drawer, that's an ideal spot because it's designed to hold humidity and is usually isolated from ethylene sources.

How to harvest mint so the bunch stays full

Pinch off leaves from the top of the stems as you use them. This encourages the plant to branch out lower down, keeping the bunch looking full and bushy instead of getting bare and leggy. Pinch just above a leaf node—the spot where leaves branch off the stem—and the plant will send out two new shoots from that point.

Avoid stripping all the leaves off one stem at a time. Instead, take a few leaves from different stems around the bunch. This spreads the harvest and keeps the bunch balanced. If a stem starts to look brown or mushy at the base, remove it entirely so it doesn't introduce bacteria to the water.

Signs that mint has gone bad and when to replace it

Mint is past its prime when the leaves turn dark brown or black, feel slimy to the touch, or smell fermented or musty. Brown spots on the leaves are usually mold or bacterial rot and mean the mint should be discarded. A few yellow leaves at the bottom are normal as the plant ages, but widespread yellowing means the bunch is declining.

If the stems become translucent or mushy, the plant tissue is breaking down and water uptake has stopped. At this point, the mint won't recover. Discard it and start fresh. Mint stored this way typically lasts two to three weeks, but the exact timeline depends on how fresh it was when you bought it and how often you change the water.

Frequently Asked Questions

Can I freeze mint instead of refrigerating it?

Yes. Wash and dry the leaves, then freeze them on a baking sheet before transferring to a freezer bag. Frozen mint works well in tea, cocktails, and cooked dishes, though the leaves become soft and aren't good for garnishing fresh plates. Frozen mint lasts several months but loses the bright texture of fresh mint.

What if my mint starts to flower?

Pinch off the flower buds as soon as you see them. Flowering uses energy the plant would otherwise put into the leaves, and the leaves often become tougher and less flavorful once the plant flowers. Removing buds keeps the leaves tender and prolongs the harvest window.

Does the type of water matter—tap, filtered, or distilled?

Tap water is fine for mint. Filtered or distilled water won't make a meaningful difference in shelf life. If your tap water is heavily chlorinated and you notice an odor, letting it sit in an open container for a few hours allows some chlorine to evaporate, but this step isn't necessary for most people.

Can I store mint in the crisper drawer instead of on a shelf?

A crisper drawer works if the mint is in water, because the drawer's humidity control keeps the air from drying out the leaves. However, the jar takes up space and can tip over if the drawer is crowded. A middle shelf is usually more practical, but either location will keep mint fresh if the water and loose plastic bag setup is in place.

How do I know if mint is fresh when I buy it?

Look for bright green leaves with no brown spots or wilting. Gently squeeze the bunch—the stems should feel firm, not soft or mushy. Smell it; fresh mint has a clean, sharp aroma. Avoid bunches with yellowing leaves or a musty smell, as these are already declining and won't last long even in the refrigerator.
