For year’s I was overwhelmed at harvest time. Mostly because I would end up with all my crops and no exact plan for preserving and storage. I didn’t have answers to some of the basic questions: What goes in root cellar storage? What goes in the freezer? What needs canning?
By the time the last of the garden is in, most homesteaders have a pile of squash, potatoes, apples, and onions sitting on the counter with no real plan for them. Not everything needs the freezer or a canning jar: a lot of it just needs the right cold, dark spot and a little know-how.
Here’s what actually stores well through winter, what doesn’t, and how to set yourself up for success even without a dedicated root cellar.

This article is part of my homestead cooking series where I share how to make from-scratch food instead of buying it at the grocery story. From homemade bread and jelly to homemade condiments. I'm Gretchen and I've been homesteading for over 15 years. Here at the Backyard Farming Connection, I connect the lines between growing your own food, raising your own animals, and putting it all together in the kitchen.
The Three Things That Matter Most
Long-term storage comes down to three conditions, and most storage failures trace back to getting one of these wrong:
- Temperature: Most root cellar crops want 32–40°F. A basement corner, an unheated mudroom, or an attached garage can all work if they stay consistently cold without freezing.
- Humidity: Root vegetables (potatoes, carrots, beets) want it humid — 90–95%. Alliums and squash want it dry — 60–70%. Storing them side by side in the same conditions is the #1 reason one or the other goes bad early.
- Airflow: Stagnant air speeds up rot. Whatever you’re using for storage, make sure air can move through it.
What Stores Well
- Winter squash & pumpkins: Cure first (see below), then store somewhere cool and dry, not cold and damp. Most varieties keep 2–6 months.
- Potatoes: Cold, dark, humid, and not near onions (onions release gases that make potatoes sprout early). 4–6 months in good conditions.
- Onions & garlic: Cool and dry, with good airflow. Braiding or mesh bags work better than sealed containers.
- Apples & pears: Cold and humid, stored away from other produce — apples give off ethylene gas that speeds up ripening (and spoilage) in everything nearby.
- Carrots, beets, turnips: Pack in slightly damp sand or sawdust in a bin; this is the classic root cellar method and it works.
What Doesn’t Belong Here
- Tomatoes, peppers, and other tender summer crops — these want the freezer, the canner, or the dehydrator, not cold storage.
- Anything already showing soft spots, mold, or damage — one bad squash in a bin can take out the ones around it.
- Leafy greens — these are a fridge crop, not a storage crop, no matter how you slice it.
Curing Before Storing
A few crops need to cure before they go into storage: this toughens the skin and seals the neck or stem end so they last.
- Winter squash & pumpkins: 1–2 weeks in a warm (80–85°F), well-ventilated spot before moving to cool storage.
- Onions & garlic: 2–3 weeks somewhere warm, dry, and airy, until the necks are fully dry and papery.
- Potatoes: A short 1–2 week cure in a cool, dark spot (not warm) helps toughen the skins before longer storage.
No Root Cellar? Here’s What Works Instead
Not everyone has a dedicated cellar, and you don’t need one:
- An unheated closet, mudroom, or three-season porch
- A cooler corner of a basement, away from the furnace
- A garage that stays above freezing but below 50°F
- A buried trash can or cooler in the ground (an old-school trick that still works well for root vegetables)
We have a large cold basement but I actually prefer to keep them in a closet off the kitchen that stayed about 55 all winter. I’ve found that the food is easier to access.

FAQ
Do I need a real root cellar to store vegetables for winter? No: any consistently cool, dark space with decent airflow will work. A basement corner or unheated porch is often enough.
Can I store potatoes and onions together? It’s best not to. Onions release gases that cause potatoes to sprout faster, shortening their storage life.
How long do winter squash actually last? Most varieties keep 2–6 months in the right conditions, with hard-shelled types like butternut and hubbard lasting the longest.
Why did my stored apples go bad so fast? Apples give off ethylene gas that speeds up spoilage in anything stored nearby, including other apples. Store them separately, and check the bin regularly for one bad apple spoiling the rest.
