Garlic looks like the crop that will look after itself. It comes out of the ground dry, it has its own paper wrapper, and it sits happily in a bowl for a while. Then in January every clove has a green shoot running through it, or a head that looked fine turns out to be soft and gray inside, and the rest of the braid follows within a fortnight.
Two things decide how long garlic keeps: whether it was cured properly, and what temperature it sits at afterward. There is also one genuine safety subject in this article, which is garlic stored in oil, and that section is worth reading even if you skip the rest. Below is the curing, the storage conditions the extension services specify, what to keep it in, and where drying takes over.

Quick Answer
How should you store garlic?
- Dry the heads down first in a warm, well ventilated spot before they go into storage.
- Iowa State University Extension gives storage at 32 to 40 degrees F and 65 to 70 percent relative humidity, with a storage life of 6 to 7 months.
- Keep whole heads in mesh, a slatted crate or a braid, never sealed in plastic and never in the fridge door.
- Never store raw garlic in oil at room temperature. NCHFP warns that garlic in oil held at room temperature is at risk for botulism.
Bottom line: cool, dry and ventilated for whole heads. Peeled cloves and garlic in oil are refrigerator or freezer items with a short clock on them.
Cure the Heads Before You Store Them
Fresh pulled garlic is full of water and the neck is still soft. Curing dries the outer wrappers into paper and seals the neck, which is what keeps the cloves inside from drying out or rotting. Iowa State University Extension lists garlic as needing to dry in a warm, dry, well ventilated location before storage.
Hang bunches or lay heads on a rack out of direct sun with air moving around them. Leave the tops on if you plan to braid. Curing is finished when the wrappers rustle, the neck is tight, and the roots are brittle. Only then should you trim.
Trim, Do Not Peel
Cut the roots close and trim the stalk to a short stub, leaving every papery wrapper intact. Peeling back the outer layer to make a head look tidy strips away the barrier you spent weeks building. Brush off dry soil rather than washing.
The Temperature That Actually Matters
Iowa State University Extension puts garlic storage at 32 to 40 degrees F with 65 to 70 percent relative humidity and gives a storage life of 6 to 7 months. Those are the same conditions it gives for onions, which is why the two crops share a shelf comfortably while potatoes need somewhere else entirely.
The awkward part is that the middle range is the worst range. Oregon State University Extension guidance on preserving garlic notes that garlic sprouts fastest between 40 and 60 degrees F, which is precisely the temperature of a cool pantry or an unheated hallway in autumn. Either go properly cold or accept a shorter counter life and eat it faster.
Softneck Keeps Longer Than Hardneck
Variety changes the answer. Oregon State University Extension guidance puts softneck garlic at up to 9 months in the right conditions and hardneck varieties at up to 6 months. Hardneck is usually the better flavored one and the one that braids badly, so plan to eat the hardneck first and let the softneck carry you into spring.
What to Keep It In
Whatever you use has to breathe. Mesh bags, slatted crates, wire baskets, open ceramic keepers with ventilation holes, or braids hung from a hook all work. A sealed jar or a zip bag traps the moisture the head is still giving off and turns the wrappers damp, which is where mold starts.
A ceramic garlic keeper is the classic countertop answer and it does its job, which is blocking light while letting air through. It is not a substitute for a cold spot, so treat it as the place a week of garlic lives rather than where the harvest lives.
Do Not Refrigerate Whole Heads
A domestic fridge sits in the range garlic reads as spring, and it is humid. Whole heads stored there tend to sprout and then soften. The fridge is the right place for peeled cloves and for anything in oil, and the wrong place for a cured head you want to keep for months.
Garlic in Oil: The One Real Safety Rule
Garlic is a low acid vegetable, and submerging it in oil creates an oxygen free environment. The National Center for Home Food Preservation states that mixtures of garlic in oil stored at room temperature are at risk for the development of botulism. This is not a cautious hedge, it is the reason commercial garlic in oil products are acidified.
NCHFP gives the safe home handling clearly: garlic in oil should be stored in the refrigerator at 40 degrees F or lower for no more than 4 days, and it may be frozen for longer term storage for up to several months, packaged in glass freezer jars or plastic freezer boxes with half an inch of headspace, labeled and dated. Roasted garlic in oil follows the same rule. There is no shelf stable home version of this.
Storage Options Compared
Whole heads, peeled cloves, frozen and dried are four different products with four different clocks. Choosing the wrong one is why people end up throwing garlic away in both directions, some sprouted and some slimy.
| Form | Where it goes | Rough working life | Watch for |
|---|---|---|---|
| Cured whole heads | Cold, dry, ventilated, 32 to 40 degrees F per Iowa State Extension | 6 to 7 months per Iowa State Extension | Sprouting if held between 40 and 60 degrees F, per Oregon State Extension |
| Peeled cloves | Sealed container in the refrigerator | Days, not weeks | Sliminess and off smell |
| Garlic in oil | Refrigerator or freezer only | No more than 4 days chilled per NCHFP | Never at room temperature |
| Dehydrated slices or powder | Sealed jar, cool and dark | Long, if it was dried to brittle | Clumping means moisture got in |
When the Heads Start Sprouting, Dry Them
A sprouted clove is still edible, just sharper and often bitter at the green core. When a whole braid starts going that way at once, the answer is to process it rather than to watch it. Drying is the most space efficient route and it turns a shelf of heads into a couple of jars.
Penn State Extension notes that onions, garlic, peppers and herbs do not need blanching before drying, which makes garlic one of the easier vegetables to dry. Our walkthrough on dehydrating garlic covers slicing, the smell problem and grinding to powder, and the food dehydrator buying guide covers which machines cope with a strong smelling load without perfuming the kitchen for two days.
Frequently Asked Questions
How long does garlic last in storage? Iowa State University Extension gives 6 to 7 months for cured garlic at 32 to 40 degrees F and 65 to 70 percent relative humidity. Oregon State University Extension guidance puts softneck varieties at up to 9 months and hardneck at up to 6 months in the right conditions.
Why is my garlic sprouting? The storage spot is probably in the worst band. Oregon State University Extension guidance notes garlic sprouts fastest between 40 and 60 degrees F, which is the temperature of most cool pantries. Go colder, or eat it faster.
Can I store garlic in oil? Not at room temperature. NCHFP warns that garlic in oil stored at room temperature is at risk for the development of botulism, and gives refrigerated storage at 40 degrees F or lower for no more than 4 days, or freezing for up to several months.
Should garlic go in the refrigerator? Whole cured heads, no. The fridge is humid and sits in the sprouting range. Peeled cloves and anything in oil, yes, and those have a short clock on them.
Can I store garlic with onions? Yes. Iowa State University Extension gives both 32 to 40 degrees F at 65 to 70 percent relative humidity, so they share conditions. Potatoes are the crop that has to live somewhere else.
Is a garlic keeper worth buying? For countertop quantities, yes, because it blocks light and lets air through. It does not make a warm kitchen into cold storage, so treat it as a week of garlic rather than a harvest.
The Bottom Line
Cure the heads, keep them cold, dry and open to the air, and stay out of the sprouting band in the middle. Peeled cloves belong in the fridge, garlic in oil belongs in the fridge for days or the freezer for months, and nothing in oil belongs on a shelf. When the braid starts to go, dry it: our food dehydrator buying guide and airtight container guide cover the two halves of that.
