25 Storage Crops to Help You Plan a Vegetable Garden that Feeds You Year-Round
By Steven Biggs
Plan a Vegetable Garden that Includes Storage Crops
I have a plan to turn a room in my basement into a proper root cellar. Braids of onions hanging from the ceiling, homegrown squash on shelves, lots of root vegetables…
But I don’t have a root cellar at the moment.
Maybe it’s the same for you.
The good news is that you can store a lot of homegrown food even if you don’t have a root cellar.
And having lots of vegetables to store starts with your vegetable garden planning. Choose crops that you can store in the garden. And choose crops that store well in protected areas other than a root cellar.
This articles helps you plan a vegetable garden with storage crops in mind.
Storing Crops
I like to think of crop storage two ways. I recommend a bit of each in your vegetable garden plan.
In-Garden Storage: Leave cold-tolerant crops in the garden to continue harvesting as the growing season wraps up.
Harvest and Store: Harvest crops and store in a protected space.
In-Garden Storage
When cool weather arrives, some plants pack it in and die. Think of basil…a little sniff of cold and it drops its leaves in protest.
But some crops do very well in cool temperatures. They soldier on even as fall frosts arrives.
Even with these cold-tolerant crops, growth slows down and stops as days get shorter and shorter. But you can continue harvesting what’s there.
Leafy Greens for In-Garden Storage
Here are my favourite leafy crops for in-garden storage. And to be clear, I’m not suggesting that I harvest any of these winter-long here in Toronto. I don’t. But they have good cold tolerance, and I’ve often picked them from under a dusting of snow.
(If you want to take you year-round harvesting to another level, think of using a combination of cold frames and cold-tolerant crops.)
Kale is very cold-tolerant. If you can only grow one cold-tolerant green, start with kale.
Kale. For cold-climate gardeners, kale is a great season extender. It’s very freeze tolerant. It keeps going as light frosts arrive in the fall. Then as things freeze hard, it still hangs on. I’ve sometimes picked kale in January from under the snow. (The winter-harvested leaves are a far cry from tender, baby kale, by the way. But if you cook it accordingly, it’s a great homegrown addition to the menu.)
Celery. Reliable until hard freezes arrive. (And if you’re thinking celery isn’t a leafy green, you’re right. Except my favourite type of celery is “leaf” celery. Leaf celery, as the name suggests, is more leaf, less stalk—and it’s far less demanding and easier to grow than regular celery.)
Chard. Reliable through those first fall frosts, until hard freezes arrive. Chard also looks great, so if you’re interested in edible ornamental gardens, consider this as you plan your vegetable garden. (Maybe you have ornamental beds that would benefit from a pop of fall colour from one of the many colourful chard varieties.)
Parsley. Reliable until hard freezes arrive. Like chard, also a great ornamental plant. Use it as edging alongside annuals somewhere near your house, so that during muddy fall weather, it’s easy to quickly grab a few sprigs for supper.
Parsley stands up nicely to fall frosts.
A Couple More In-Garden Storage Crops
Keep harvesting cardoon until there’s a hard freeze.
Leek. Like kale, a plant you can keep harvesting into winter. And when there’s a mid-winter thaw, you can go get some more. The leaf tips begin to brown mid-winter…but that’s fine because it’s the lower portion we eat.
Cardoon. Cardoon keeps going through light frosts. It’s leaves wilt, and then spring back up as the day warms. (If you haven’t grown cardoon before, remember to blanch it or it’s horrid…my first forays into cooking cardoon didn’t win me any favours with my family!)
In-Garden Storage Using Straw Bales
As fall frosts arrive, there’s no rush to harvest many of the in-ground root crops. Carrots and parsnips are improved by frost.
A simple way to extend the time you can leave them in the ground is to place a straw bale over top of them. It insulates them and the ground below.
With a heavy mulch, you can leave carrots and parsnips in the ground until the soil freezes solid. Where I am, that’s midwinter. And the longer they’re in the ground, the better they last.
One more thought on leaving roots crops in the garden late: Remember that while carrots and parsnips usually grow under the soil and protected from the first freezes, beet roots often shoulder their way above the soil surface. Those exposed shoulders are quicker to freeze…and that affects the quality.

Harvest-and-Store
First things first: A root cellar is nice…but if you don’t have one, there are other ways to successfully store your harvest. Think about your storage options now, as you plan a vegetable garden. That way you can plant accordingly.
Here are different places you might be able to store your harvest:
Swiss chard with some frost on it. It will spring back up once the sun comes out.
Garage. My garage doesn’t freeze, so I use it to store root crops (and apples that I buy by the bushel…great way to save money). My garage stays just above freezing, and is fairly humid, making is well suited to storing produce.
Clamp. This is a traditional way or insulating harvested root vegetables outdoors, using soil and straw.
Cooler area in a heated basement. I have a room in my basement where I shut off the heat vents. It’s cooler (and darker) than the rest of the house. It’s not as humid or cool as a proper root cellar, but is excellent to store winter squash, garlic, and onions.
Unheated basement. A friend had an unheated basement with an earthen floor…perfect for stored crops!
Sunroom. If you have a sunroom that stays just above freezing through the winter, I’d be thinking about food storage…
Breezeway. Some houses have a minimally heated breezeway between the house and garage. It’s just calling out for food storage!
Attic. If you have an accessible attic, another option for cool storage! The logistics of carrying food up to an attic aren’t ideal, but if it’s all you have, worth a try.
Successfully Storing Crops
Storing crops in the right conditions can really extend the storage life.
Root crops can go into perforated plastic bags, or into moist sand or sawdust in crates. This prevents them from drying out.
Newspaper comes in handy too: cover trays of green tomatoes with a sheet of newspaper; and wrap cabbages in a sheet of newspaper.
Only store unblemished produce. If you have crops that aren’t good enough to store, cook them up or freeze them.
Harvest-and-Store Crops
Dry Bean
When the pods turn light brown, just pull up the entire plant to hang upside-down under cover to dry further. Great storage crop for long-term storage.
Beet
Leave a half inch of stem on the roots as you prepare to store beets. Then they won’t “bleed” as much. Look for varieties recommended for storage. A favourite of mine over the years has been ‘Cylindrda.’
My favourite storage crop! (I make beet borsch with some of mine every year.)
Cabbage
Not a crop that lasts all winter in a root cellar, but you can keep it for a couple of months. The outer leaves dry, and you’ll peel those off as you prep the cabbage for use in the kitchen.
Use midsummer transplants to grow cabbages for winter storage. Harvest as late as possible for storage.
(Don’t forget that you can also use some cabbage to make sauerkraut. Find out how to make your own sauerkraut.)
Cabbage, along with other cole crops such as broccoli, cauliflower, and Brussels sprouts are also excellent for in-garden storage as they keep going through early fall frosts.
Carrot
Use midsummer transplants to grow cabbages for winter storage. Harvest as late as possible for storage.
Sweeter after some frost. Look for varieties recommended for storage. ‘Bolero’ is a variety that I like for storage.
Cerleriac (a.k.a. celery root)
Often overlooked, and a great addition for gardeners growing for storage.
Garlic
Easy to grow lots in a small space, and easy to store for gardeners without many storage options, because it and onions like things dryer than the root crops.
Horseradish
As you’re planning your vegetable garden, remember that this is a deep-rooted perennial. So pick a permanent spot for it.
Jerusalem artichoke
A somewhat invasive perennial, so pick a permanent spot for it.
Onion
Braided onions drying before going into storage.
Store onions after curing. Like garlic, important to dry and cure for a couple of weeks before storage. If not properly cured, doesn’t last as long.
You don’t have to braid onions. Another way to store them is to hang them in a mesh bag—so there is good air circulation around the onions.
Parsnip
Sweeter after they go through some frost.
(One year I grew far too many parsnips, and had the brilliant idea of making parsnip wine. Alas, it was horrid…couldn’t even use it as cooking wine.)
Peppers
Often overlooked, but smaller, thin-skinned pepper varieties are easy to dry. Once dry, you can hang them in your storage area, where there’s good air circulation.

And get an early harvest of crops that usually take too long!
Potato
Plan for your storage potatoes to be ready late in the season. During the summer, storage spaces aren’t usually as cool as they are in the fall—so your potatoes can sprout quickly when stored too early.
Don’t put early potato harvests into storage. Plan for a later harvest for storage.
Radish (winter)
So often overlooked, and a great addition in a storage-focused garden.
Root Parsley
Ditto above.
Rutabaga
My mother-in-law’s must-have cooked veg at the Thanksgiving table!
Squash
Pick before light frosts for best storability.
Tomato (keeper)
Keeper tomatoes in the spring.
It’s easy to overlook tomatoes as a storage crop, but there are thick-skinned tomato varieties that can last until spring! They’re called “keeper” or “winter” tomatoes.
These aren’t great for tomato sauce, but are nice chopped into a salad or bruschetta.
