If you have an area in your basement that stays cool all winter long, you can make use of these cold spots to keep storage crops fresh well into winter. Try experimenting with growing some of these keeper crops for winter food storage
I began growing my own food with a small, weed filled garden that came with the home I purchased. The first year, I grew a few herbs and some vegetables for fresh eating during the summer. The following year, I thought it would be fun to learn how to can and planted extras to preserve tomato sauce, salsa, carrots, and string beans. I remember organizing the jars on shelves in the basement, taking a step back, and feeling such a sense of pride. I felt so gratified and accomplished that I grew and preserved my own chemical free food to enjoy through the winter. I wondered what else I could grow to get us through until the garden produced again.
The years that followed involved expanding the garden and improving the soil so I could grow and preserve even more. Our basement is unheated and stays between 40-50˚F all winter so I also experimented with crops that can be stored in baskets, on shelves, or in buckets of damp sand without dehydrating, freezing, or canning.
These are the top keeper crops that I grow each year for winter food storage:
9 Crops to Grow for Food Storage
Choose onion or shallot varieties that are known for their long-term storage capabilities. Since different varieties are triggered to bulb by day-length, also be sure to select varieties for your growing area. My favorite onions to grow for long-term storage are Copra, Stuttgarter, and Redwing.
In northern climates, onions are planted in early spring. Allow onions to mature fully to ensure the greatest storage capability. Onions are finished growing when the tops flop over, and the foliage begins to turn yellow. Harvest the onions on a dry day taking care not to damage or bruise the bulbs. Cure the onions by spreading them out in a single layer in a dark, cool, and dry location with good airflow. Allow onions to cure for several weeks or until the tops are completely dry and no green is visible when trimming the foliage. Once cured, trim tops to 1-inch and store loosely in baskets or mesh bags in a cool, dark, and dry location for winter. Check the onions every few weeks and remove any that develop soft areas. Different varieties and storage conditions will affect how long they last. Our onions usually last until April before they begin to get soft and sprout.

Select varieties that grow well in your area. Softneck varieties have a reputation for storing well and are suited for growing in mild climates. Hardneck varieties are more suited for areas with cold winters.
Garlic is planted in the fall, harvested the following summer, and cured before storing. Curing allows the layers to dry out forming a protective cover around the bulb. Store cured garlic loosely in baskets or mesh bags in a cool, dark, and dry location. Sort through the garlic every now and then and pull out any bulbs that feel soft. Different strains and varieties of garlic have different storage lives; ours usually last until April before it begins to sprout. Also see: Planting Garlic in the Fall Garden and Harvesting, Curing, and Storing Garlic for more detailed information.
Rutabagas are a long-season crop that requires at least 90 days to mature. Sow seeds three months before your first expected fall frost (look up yours here). Depending on the variety, thin seedlings to 6 to 12 inches apart so the roots have room to expand. Variety to consider: American Purple Top.
Rutabagas can withstand light frosts but harvest before a hard freeze. Harvest gently and trim tops and tap root to 1-inch. Brush off loose soil, but do not wash. Store rutabagas in buckets or totes packed with damp sand or sawdust. Ideal storage condition for rutabagas is at a temperature of 32- 35˚F and 90% humidity. They shrivel easily, so check sand frequently and re-moisten if needed. Under these conditions, rutabagas usually last 2 to 4 months in storage.
Celeriac, also known as Celery Root is a long season crop that needs 90 to 120 days to reach harvest. Seeds are sown early indoors under lights 10 to 12 weeks before the average last frost date and transplanted hardened off seedlings to the garden about two weeks before your last frost date. Celeriac has similar growing requirements as it’s cousin, celery and needs lots of water. Self-watering containers are ideal for growing celeriac.
Celeriac can tolerate light frosts but harvest before a hard freeze. Harvest and trim tops and gnarly roots to 1-inch. Shake off loose soil, but do not wash. Store celeriac in buckets or totes packed with damp sand or sawdust. Ideal storage condition is at a temperature of 32- 40˚F and 90% humidity. They shrivel easily, so check sand frequently and re-moisten if needed. Under these conditions, celeriac usually last 2 to 4 months in storage.
Choose carrot varieties that are known for their long-term storage capabilities. Start seeds late in the season so the carrots are mature by frost. Varieties to consider: Chantenay, Imperator, and Danvers.
Carrots can be left in the ground though light frosts, but dig before the ground freezes for longer storage potential. Trim foliage, brush off excess soil, and sort by size. Larger carrots seem to last longer in storage. Layer the carrots in sand or sawdust in a box or tote beginning with the largest ones on the bottom so you can use up the smaller ones first. Ideal storage condition is at a temperature of 32- 35˚F and 90% humidity. Under these conditions, carrots can last 4 to 6 months in storage. Homemade Seed Mats make sowing carrot seeds easy.
Parsnips require a full season of growth. Sow in early spring and keep moist until seeds germinate, which could take up to 3 weeks. Depending on the variety, thin seedlings to 2 to 4 inches apart so the roots have room to expand. Variety to consider: All American.
Parsnips should be left in the ground until frost to sweeten the flavor, but dig before the ground complete freezes. Trim foliage, brush off excess soil, and sort by size. Layer the parsnips in sand or sawdust in a box or tote beginning with the largest ones on the bottom so you can use up the smaller ones first. Ideal storage condition is at a temperature of 32- 35˚F and 90% humidity. Under these conditions, parsnips can last 3 to 5 months in storage.
Select late season potato varieties that are known for their winter storage capabilities such as Yukon Gold, Katahdin, and Kennebec. Plant potato seeds according to your chosen potato planting method. Once the foliage has withered and the plants have finished growing, allow the potatoes to remain in the soil until the end of the season. This allows the skins to thicken up a bit to resist scratching when harvesting. Dig the storage crop of potatoes before the ground freezes. Choose a warm, dry day after a period of little or no rain.

Plant winter squash and pumpkin in the spring after all danger of frost is past. Harvest ripe squash at the end of the season before frost and cure before storing. Usually by the end of summer, the squash vines have shriveled and died, and I leave the mature squash in the garden to field cure. Alternately, you can harvest squash by cutting the vine and leaving a 1-inch stem. The stem helps prevent rot when you are keeping winter squash in storage. Do not carry the squash by the stem because it can break off reducing the storage quality of the fruit. Cure at 80 to 85˚F for about 10 days. Curing allows the squash’s skin to thicken and form a protective barrier.
Store cured squashes in an area that is dry, cool, and receives good air circulation. Ideal storage condition for winter squash and pumpkins is at a temperature of 50-55°F and 50-70% humidity. I store mine on wire shelves near the basement stairs because it remains a little warmer than the rest of the basement. Most winter squash and will keep for several months in storage. Some, such as Butternut and Blue Hubbard can last up to 6 months.
Select bean varieties suitable for drying and plant in early spring after all danger of frost is past. There are so many varieties of dried beans to choose from that mature in under 100 days.
Allow the beans to dry on the vine and harvest in early October before frost. Spread the pods out in a single layer and allow them to dry completely before shelling. To test the beans, hit them with a hammer and the bean should shatter. Shell and store in jars in a dark and cool area. Dried beans will easily last up to a year in storage.
Tips for Successful Food Storage
