Families relied on root cellars for generations to keep their harvest fresh through the long winter months. But what if you don’t have a root cellar, or even a basement? Can you still store your homegrown carrots, beets, potatoes, and cabbage for months at a time?
The answer is yes! In this interview with Sam Knapp of Off Beet Farm, a small vegetable farm in Alaska specializing in winter storage crops, we dig into the practical ways you can master root vegetable storage even without a traditional root cellar.

🥕 TL;DR – Root Vegetable Storage Without a Root Cellar
You don’t need a traditional root cellar to store your harvest through the winter. In this post, you’ll learn:
- 🌡️ The 3 keys to storage success: temperature, humidity, and airflow
- 🧊 Easy methods like a spare fridge, Rubbermaid totes, or packing in sand/wood shavings
- 🥔 Which vegetables are the most forgiving (potatoes, carrots, cabbages, beets)
- ✂️ Harvest prep tips: trim tops, cure squash/onions, and keep cabbage wrapper leaves
- ⚠️ Solutions for common issues: shriveling, condensation, and rodents
- 🌱 The best varieties for long-term storage—from ‘Bolero’ carrots to ‘Sweet Mama’ squash
Bottom line: With these simple tips, you can enjoy fresh, homegrown root vegetables all winter, no root cellar required!
Why Root Vegetable Storage Matters
Root vegetables (carrots, beets, parsnips, turnips, rutabagas, potatoes) are nutrient-dense, hearty, and naturally long-lasting. Learning how to store them properly means you can enjoy local, homegrown food all winter long without relying on the grocery store.
While we don’t all farm in Alaska, where it’s a bit easier to keep temperatures low, the same principles can be applied to almost any climate.
Three Keys to Storing Root Vegetables
Sam emphasizes that successful storage really comes down to three things:
- Temperature – Most root vegetables want to be kept just above freezing (32–35°F).
- Humidity – High humidity keeps vegetables from shriveling and drying out.
- Airflow – Even in storage, vegetables are alive and need to “breathe.” A bit of airflow prevents condensation and rot.
How to Store Root Vegetables Without a Root Cellar
1. Use an Extra Refrigerator
One of the simplest solutions for modern homesteads is to set aside a spare fridge just for produce.
- Keep the temperature as close to 32°F as possible.
- Store vegetables in perforated plastic containers or bags to hold humidity while still allowing airflow.
- Carrots, beets, parsnips, and cabbage can last months this way.
2. Room Temperature Options
Not every crop needs cold temperatures or high humidity:
- Onions, garlic, pumpkins, and winter squash prefer a dry environment and can be stored at room temperature once cured.
- Store them on shelves in a pantry or closet with good airflow.
- Monitor them closely and use up any that are showing signs of spoilage so that they don’t spread it to the other crops.
3. Sand, Sawdust, or Wood Shavings
If you don’t have an extra fridge, you can recreate traditional methods:
- Pack root vegetables in damp sand or wood shavings inside boxes or totes.
- This keeps humidity high and slows down moisture loss.
- Avoid pine or cedar shavings, which can impart strong flavors to your vegetables.
- Choose areas of your home where the temperature stays the coldest (an outside wall tucked in the corner, a basement, a garage, etc.)
4. Rubbermaid Totes & Trash Bag Trick
For small-scale home storage, Sam suggests:
- Drill small holes in plastic totes for airflow.
- Place vegetables inside, then loosely drape a trash bag over the top.
- This holds humidity in while letting them breathe.
5. In-Ground Storage (for Mild Winters)
In temperate regions, some root crops like carrots and potatoes can be left in the ground. You can see how I store potatoes during the winter here. The short and sweet tutorial is to:
- Mulch heavily with straw or leaves to insulate.
- Harvest as needed through the winter.
- This method doesn’t work in areas with deep freezes, but where winters are mild, it can be the easiest solution.
Which Vegetables Are the Most Forgiving?
If you’re new to storage, start with the foolproof crops:
- Potatoes – They tolerate slightly warmer temps and store for months.
- Cabbages – The outer leaves protect inner layers; just peel away the dried or damaged leaves and use.
- Carrots and beets – Even if they soften a little, they’re still delicious and often sweeter due to the more concentrated sugar content.
Harvest & Prep Tips
- Cure onions, garlic, and squash – Let them dry in a warm, airy space before storing. You can learn how to cure onions here and how to braid garlic here. Also, check out how to plant garlic in the fall here.
- Trim greens before storage – Carrot tops, beet greens, and other foliage pull moisture from the roots and invite rot.
- Leave wrapper leaves on cabbage – They act as natural protection.
- Don’t seal containers airtight – Vegetables need to breathe.
Watch for Humidity Issues
One of the biggest storage mistakes is focusing only on temperature while ignoring humidity. Low humidity causes vegetables to shrivel, while too much humidity can cause rot.
- Solution: Add a humidifier in your storage space, or use enclosed containers (with airflow). For too much humidity, consider adding some dry wood shavings to help absorb the excess moisture.
- Pro Tip: Once vegetables get too shriveled or show signs of rot, you can’t fully revive them, but catching it early can help slow further loss.
Pests and Problems
- Rodents – Cats, traps, and rodent-proofing (hardware cloth, metal flashing) are essential if you’re storing outside or in sheds.
- Slugs and insects – These tend to be less of an issue when storing crops at colder temperatures because they become inactive. It’s easy just to peel away affected layers.
- Condensation – If storing in basements or enclosed spaces, use vapor barriers to avoid mold from condensation buildup.
Choose the Right Varieties
Not all vegetables store equally. Look for “storage varieties” in seed catalogs.
- Carrots – ‘Bolero’ and ‘White Satin’ are excellent long-term keepers.
- Onions – Long-day varieties like ‘Copra’ or ‘Patterson’ last for months.
- Squash – Spaghetti squash (‘Pinnacle’), Delicata and kabocha types (‘Sweet Mama’) perform well.
Longer days-to-maturity often correlate with better storage life, while faster-growing varieties may not last as long.
As you can see, you don’t need a root cellar to store root vegetables successfully. With some planning, creativity, and the right conditions, you can keep your harvest fresh all winter long.
Start simple, maybe with a spare fridge and some plastic bins, and experiment from there. Each year, you’ll learn more about how your specific varieties and climate behave in storage.
By following these tips, you can enjoy homegrown carrots, beets, cabbages, and more long after the garden is put to bed.
