How to Store Cabbage: Cold, Moist Storage for Whole Heads
As an Amazon Associate we earn from qualifying purchases.
Learning how to store cabbage comes down to two goals: keep whole heads cold and humid enough that they do not dry out, and keep them free of damage that invites rot. Whole, undamaged heads keep far longer than cut or shredded cabbage. The extension sources below describe two routes, a perforated plastic bag in the refrigerator and a cold, moist storage site such as a root cellar, along with the storage periods they give for each. Harvest timing and variety also affect how long a head will keep.
Quick answer
- For storage lasting a few weeks, place whole, firm heads in a perforated plastic bag and keep them in the refrigerator.
- For longer storage, a cool, moist site around 32 degrees Fahrenheit with 98 to 100 percent relative humidity is described as required for storage of up to 3 to 4 months.
- Wash heads only when you are ready to use them, since surface moisture can encourage decay.
- Check stored heads regularly and remove any leaves that have softened or rotted. For a broader comparison of storage methods for other crops, see how to store freshly harvested vegetables.
How we chose
This guide relies on university extension publications and extension question-and-answer pages. Extension material is written for home growers and reflects regional growing and storage research, which makes it a better basis for storage advice than general cooking sites. The sources were located through web search, and each link was checked for a successful response before its text was read. Quotations in the source notes are copied from the fetched text. Pages that did not load, returned errors, or returned an access block were not used.
Start with sound, well-formed heads
Storage success begins at harvest, and the growing conditions matter as much as the storage method. Readers who are still growing their crop can compare these storage notes with how to grow cabbage in containers for planning. Heads that are firm, free of splits, and free of insect damage store better than heads that are already softening. Heads with cracked or damaged outer leaves are more likely to decay, so these are best used first rather than held back for storage.
The Iowa State guidance on harvest timing also notes that heads can split when they are left in the garden too long after reaching maturity. A split head loses some of the tight, protective wrapper that helps it keep, so it should be used promptly. Heads that are cut with a few outer wrapper leaves still attached tend to be better suited to storage than heads stripped to the core. The WSU publication recommends discarding outer leaves that are damaged or decayed, which is consistent with keeping the sound leaves on the head while removing those that are already failing.
Option one: the refrigerator
For most home kitchens, the refrigerator is the practical option. The Iowa State publication states that cabbage may be placed in a perforated plastic bag and stored in the refrigerator. The perforations allow a small amount of air exchange, which helps prevent the condensation that can build up inside a sealed bag. The WSU publication describes the same approach, saying cabbage is best kept in a perforated plastic bag in the refrigerator.
A refrigerator is cold but tends to be dry compared with a root cellar. The bag helps hold moisture around the head, which slows the drying of the outer leaves. Place the bag in a crisper drawer if your refrigerator has one, and keep it away from strong-smelling foods, since cabbage can pick up odors when stored for weeks. The sources do not give a single number of days for refrigerator storage, so check heads every week or two and use any that show softening first.
Option two: a cold, moist storage site
For storage lasting months rather than weeks, extension sources point to a cool, moist site. The Iowa State publication describes a site at 32 degrees Fahrenheit with 98 to 100 percent relative humidity, and states that such a site is required for prolonged storage of up to 3 to 4 months. The WSU publication says that cabbage can also be stored in a root cellar or another microclimate area with cold, moist conditions.
Few home settings match these conditions exactly. A root cellar, an unheated basement corner that stays cold and does not dry out, or a buried container in a cool area may come close, but the sources do not describe how to build or adapt such a space. A home that is cold but very dry will shorten storage, because the outer leaves lose moisture and the head becomes light and soft. If you have such a space, check heads on a regular schedule and use the most advanced ones first.
Preparing heads for storage
Harvest cabbage on a dry day and leave the outer wrapper leaves on. These leaves protect the head and help it hold moisture. Remove only leaves that are damaged or decayed. Do not wash the heads before storage, since surface water can speed rot. Trim the stem only as much as needed to remove loose or broken material, and avoid tearing the head apart.
The Iowa State guidance notes that pulling the plant upward and gently twisting can reduce root damage, and that broken roots reduce water uptake while the plant is still growing. For storage, the practical point is simply to start with heads that are sound and dry, since the harvest method affects the head before it reaches storage.
Checking stored cabbage
Inspect stored heads every one to two weeks. Look for soft spots, slimy outer leaves, and a sour smell, and remove any affected leaves or heads promptly. A head that is only slightly softened on the outside may still be usable after trimming away the damaged leaves. Use the most advanced heads first. Keeping storage cool, moist, and well ventilated helps slow the changes that make heads unusable.
What we could not verify
The two sources used here give storage conditions and time ranges, but they do not answer every question a home grower may have. Where the sources are silent, this guide does not fill the gap with unsupported detail.
What the sources do not say
The sources do not give a specific number of days for storage in a standard household refrigerator. They do not describe how to convert an unheated room, a closet, or a garage into a cold, moist storage site. They do not address storage of shredded or cut cabbage, and they do not compare how individual cultivars store. Specific storage periods for particular varieties were outside the scope of the two publications read.
The sources also do not describe how to freeze, dry, or can cabbage for long-term keeping, and this guide does not cover those methods. Anyone preserving cabbage by those methods should follow current tested guidance from a university extension service or the USDA National Center for Home Food Preservation.
Frequently asked questions
Should I wash cabbage before storing it?
The sources reviewed here advise keeping outer wrapper leaves on and avoiding unnecessary handling before storage. Surface water on the leaves can encourage decay, so wash heads just before use rather than before storing them.
Can cabbage go in the refrigerator in a plastic bag?
Yes. The Iowa State and WSU publications both describe storing cabbage in a perforated plastic bag in the refrigerator. The perforations allow some air exchange, which helps limit moisture building up inside the bag.
How long can cabbage store in a cold, moist place?
The Iowa State publication gives a range of up to 3 to 4 months for prolonged storage at 32 degrees Fahrenheit and 98 to 100 percent relative humidity. Real conditions in a home are rarely this exact, so checking the heads regularly is the best way to judge how long a given head will last.
Should I remove the outer leaves before storing cabbage?
No. The sources recommend keeping the outer wrapper leaves on, because they protect the head. Remove only leaves that are already damaged or decayed.
What should I do with cabbage that has begun to soften?
Remove any decayed or slimy outer leaves and use the head promptly. A head with only slight softening on the outside may still be usable once the damaged leaves are removed, but a head with widespread rot should be discarded.
