Celery lasts 1 to 2 weeks in the refrigerator with basic storage — but wrapped properly in aluminum foil, it stays crisp for 3 to 4 weeks, sometimes longer. That foil trick sounds like internet folklore, but it’s real: foil lets the ethylene gas celery naturally produces escape while keeping moisture in, which is exactly the combination that keeps stalks snappy. Plastic wrap, by contrast, traps the ethylene and speeds up decline.
Celery’s enemy is water loss. Those stalks are about 95 percent water, and once they start drying out, they go limp fast. Everything about storing celery is a moisture-retention strategy — with one important twist that separates it from most vegetables.
How Long Celery Lasts by Storage Method
- Wrapped in aluminum foil (best): 3–4 weeks, sometimes up to 5
- In the crisper drawer, unwashed: 1–2 weeks
- In plastic produce bag: 1–2 weeks, but often goes limp faster than foil-wrapped
- Cut sticks in water: 4–5 days of peak crispness (great for snacking, short-lived)
- At room temperature: 1–2 days before wilting sets in
The foil method deserves emphasis because the difference is dramatic. America’s Test Kitchen and countless home cooks have tested this: foil-wrapped celery at week three is crisper than plastic-wrapped celery at week one. The science is simple — celery emits ethylene gas as it ages, and ethylene accelerates ripening and decay. Foil is breathable enough to let ethylene escape; plastic isn’t. Meanwhile both keep moisture in, which is what prevents limpness.
The Right Way to Store Celery, Step by Step
Don’t wash it first. Wash celery right before you use it, not before storing. Extra surface moisture invites mold and sliminess during storage — the same rule that applies to most vegetables. (If you’re prepping snack sticks for the week, that’s the exception — see below.)
Wrap the whole head tightly in foil. Tear off a generous sheet of aluminum foil and wrap the entire bunch snugly, folding the ends closed. You want moisture trapped in and ethylene able to diffuse out — foil does both.
Store in the crisper drawer. The high-humidity drawer is ideal. Keep celery away from ethylene-heavy fruits like apples, pears, and bananas if you can — though the foil mitigates most of this.
Check weekly. Peel back the foil every week or so and pull any outer stalks that are starting to soften. One declining stalk can drag down its neighbors.
Storing Cut Celery Sticks
If you’ve already cut celery into sticks — for snacking, lunchboxes, or a party platter — the rules change. Cut celery dries out much faster because of all the exposed surface. The fix: submerge the sticks in cold water in a sealed container in the fridge. They’ll stay remarkably crisp for 4 to 5 days. Change the water every couple of days.
This water-bath method is also a rescue technique: limp whole stalks often perk back up after a few hours in ice water. It won’t save celery that’s actually spoiled (slimy or foul-smelling), but for merely dehydrated stalks, it’s genuinely effective — the cells reabsorb water and firm up.
How to Tell If Celery Has Gone Bad
Limp and bendy — but otherwise fine. This is dehydration, not spoilage. Still safe; revive in ice water or relegate to cooked dishes where texture doesn’t matter. Soups, stocks, and stir-fries don’t care about crunch.
Stringy, pithy, hollow stalks. Older celery develops a woody, hollow core. Safe to eat but unpleasant raw — peel the strings and cook it, or compost it if it’s severe.
Brown or black discoloration. Some browning on cut ends is just oxidation — trim it off. But dark streaks running through the stalk, or blackened patches, indicate decay. Cut generously around small spots; discard heavily affected stalks.
Slimy texture or sour smell. This is the real discard signal. Sliminess means bacterial breakdown, and no amount of rinsing fixes it. If the whole bunch smells off, the whole bunch goes.
White fuzz. Mold — discard affected stalks and check the rest carefully. Unlike hard cheeses, you can’t just cut mold off celery and call it good, because the high moisture content lets it spread invisibly.
Can You Freeze Celery?
Yes, with a caveat: frozen celery loses its crunch permanently. Freeze it only for cooked uses — soups, stocks, stews, mirepoix. Dice it first (no blanching strictly required, though 2–3 minutes of blanching preserves color and nutrients better), spread on a sheet pan to freeze individually, then bag. It keeps 8 to 12 months frozen. Add it directly to hot dishes from frozen; don’t thaw first.
Honestly, though, given that foil-wrapped celery lasts a month in the fridge, most people never need to freeze it. Freezing is the move when you bought the giant bag from the warehouse club and week three is approaching.

FAQs
Why does celery go limp in the fridge?
Moisture loss. Celery is 95% water, and dry fridge air pulls it out through the stalk surface. Wrapping in foil (or submerging cut sticks in water) prevents this. Limp celery is dehydrated, not rotten — ice water often revives it.
Is it better to store celery in foil or plastic?
Foil, by a wide margin. Foil lets ethylene gas escape while retaining moisture; plastic traps ethylene and accelerates decay. In side-by-side tests, foil-wrapped celery stays crisp roughly twice as long.
Can you eat celery that’s a little brown inside?
Light browning is usually oxidation or natural aging — trim it and the rest is fine. Dark brown or black streaks through the stalk indicate decay; discard those stalks.
How long does celery last once cut?
Cut celery sticks last 4–5 days submerged in water in a sealed container in the fridge. Left exposed to air, they’ll go limp within a day or two.
Does celery need to be refrigerated?
Yes, for any storage beyond a day or two. At room temperature, celery wilts within 1–2 days and becomes a bacterial risk once cut. The fridge’s cold, humid crisper drawer is its natural habitat.
