## A Survival Garden That Feeds a Family

Lettuce and tomatoes will not carry a household through a hard winter. Potatoes, beans and squash will, if you plant enough of them.

By Ruth Calloway, November 11, 2026

A survival garden feeds a family when most of its ground goes to calorie crops that store without power: potatoes, sweet potatoes, dry beans, winter squash and, where there is room, corn or another grain. Salad greens and tomatoes fill a narrow strip for vitamins, and the garden is sized to the share of the family's calories you want it to supply, which on a suburban lot is usually a quarter or less.

Most garden plans fail that test. A typical backyard bed of tomatoes, peppers, cucumbers and lettuce produces a lot of food by the bushel and very little by the calorie, and it is all eaten fresh by September. The plan below is built the other way around: count the calories first, pick crops that keep in a cellar or a jar, then see how much ground it takes.

### What a garden can really feed

Start with the size of the job. Food labels in the United States use a 2,000-calorie day as their reference. A family of four eating at that level goes through about 8,000 calories a day, or close to 2.9 million in a year. Every garden plan should be measured against that number, because it is far larger than most people guess. Patrice Lewis, writing in [Mother Earth News](https://www.motherearthnews.com/organic-gardening/vegetables/what-size-garden-feed-family-zm0z26fmzols/), puts it plainly: people vastly underestimate how much food they eat in a year.

Then look at what a row gives back. The [LSU AgCenter's expected yield table](https://www.lsuagcenter.com/topics/lawn%5Fgarden/home%5Fgardening/vegetables/expected-vegetable-garden-yields) gives figures per 100 feet of row in a good Southern home garden. Pair those weights with the calorie values in USDA's FoodData Central and the four storage crops come out like this:

| Crop           | Lb/row | Cal/lb | Cal/row |
| -------------- | ------ | ------ | ------- |
| Potatoes       | 200    | 350    | 70,000  |
| Sweet potatoes | 200    | 390    | 78,000  |
| Winter squash  | 150    | 190    | 28,000  |
| Dry beans      | 10     | 1,560  | 15,600  |

Rows are 100 feet long. The bean yield comes from a grower Mother Earth News cites, who reports about 5 pounds of dry beans per 50-foot row, since the LSU table lists only green and lima beans. Calories are for the raw crop with its skin, so the food on the plate runs a little lower once you peel and trim.

One 100-foot row of potatoes, then, covers a family of four for something like nine days. Other extension services report lower yields than LSU's Deep South figures (Mississippi State lists 150 pounds of potatoes per 100-foot row), and a first-year garden on tired soil will land lower still. The point of the math is to set your expectations before you buy seed: a garden that supplies a quarter of a family's calories is a serious undertaking, and one that supplies all of them is a farm.

### Best crops for food security

Four crops carry most survival gardens, and Lewis names the same core list: corn, potatoes, beans and squash, because they are prolific and store well. Each earns its place for a different reason.

**Potatoes** are the calorie crop for most of the country. They grow from saved tubers, tolerate cool springs and indifferent soil, and come out of the ground ready to store. Mother Earth News puts the contrast in one line: the same raised bed that gives 30 pounds of potatoes might give 2 pounds of dry beans. Plant certified seed potatoes rather than grocery tubers, which may carry disease or be treated against sprouting, and plan for curing and cold storage from the start. Our guide to [building a root cellar](/homestead/how-to-build-a-root-cellar) covers the curing schedule and the 38 to 40 degree room that holds them through winter.

**Sweet potatoes** take over where summers are long and hot. They give a little more food energy per row than white potatoes in the LSU table, the leaves are edible, and they need warm storage at 55 to 60 degrees rather than a cold cellar, which a spare room in the house can provide. In the North they are a gamble. In the South they may be the better bet of the two.

**Dry beans** are the protein. The yield by weight is small, but every pound is dense food that keeps for years in a sealed jar with no cellar, no canner and no power. Let the pods dry on the vine, pull the plants before fall rains, and thresh them on a tarp. Beans also feed the soil with nitrogen from the bacteria on their roots, which helps whatever follows them in the bed.

**Winter squash** gives fewer calories per pound but stores for months on a shelf in a cool room and supplies vitamin A the starch crops lack. The vines sprawl, so plant it at the edge of the garden where it can run onto the grass, or grow it under corn the way the Three Sisters planting does, with pole beans climbing the stalks.

**Corn and grain** belong on bigger plots. A flour or dent corn, dried on the stalk and ground as needed, turns the garden into a source of bread and porridge. Wheat, oats and other grains need more space than most backyards have and tools to thresh and grind them, and Ecology Action notes that a diet built mainly on grains takes more land than one built on potatoes. Treat grain as the step after the first three crops are working.

Behind those come the supporting calorie crops that fit odd corners: Jerusalem artichokes along a fence, which come back every year, plus rutabagas, turnips, beets and carrots, which store in the same cellar as the potatoes and give a second harvest from late-summer sowings.

### The vitamin strip

A garden of starch alone would leave a family short of vitamins C and A, folate and the variety that keeps people eating. Ecology Action's planning ratio gives this part of the plot about a tenth of the space, enough for the greens, tomatoes and peppers a household eats fresh and puts up for winter. Their FAQ explains that this small area supplies the vitamins and minerals the calorie crops lack.

Choose vitamin crops that keep producing late into the year or store well. Kale and collards stand through frost and can be picked leaf by leaf into December in much of the country. Cabbage keeps in the cellar for months. Onions and garlic store on a dry shelf and make plain food worth eating, which matters more than it sounds when the menu is potatoes and beans for weeks at a stretch. Tomatoes are worth a row or two for canning, since tested recipes put them up in a boiling-water canner with a little added lemon juice or citric acid, no pressure canner needed.

### How much ground for four

Estimates range widely, and the reasons for the spread tell you more than any single figure. Ecology Action, the group behind John Jeavons' GROW BIOINTENSIVE method, says on its [FAQ](https://www.growbiointensive.org/FAQ/FAQ%5FRawFood.html) that a complete diet for one person realistically takes 4,000 square feet at its intermediate yields. That is 16,000 square feet for a family of four, a little over a third of an acre, worked in deep-dug, heavily composted beds by people who know the method.

Ecology Action's split: about 60 percent grain and compost crops, 30 percent root crops, 10 percent vegetables and fruit.

Their plan splits the ground 60/30/10: sixty percent in grain and compost crops whose stalks go back into the soil, thirty percent in root crops such as potatoes, and ten percent in vegetables and soft fruit. The large grain share exists to feed the soil as much as the people, so the garden can keep producing year after year without bought fertilizer.

Lewis gives a more conservative figure for ordinary gardening: at least a quarter acre for a family of four, before any room for livestock, field grain or hay. She also notes that the often-quoted 1,200 square feet for a family leaves out paths and the room squash vines need.

For a household that wants a share of its calories, the table above gives a working size. A quarter of a year's food for four is about 730,000 calories, or ten to fourteen 100-foot rows of potatoes depending on yield. LSU assumes rows 36 to 42 inches apart, so each row takes roughly 300 to 350 square feet, and the whole potato patch comes to 3,000 to 5,000 square feet. Swap some potato rows for beans and squash and the area grows, because both give fewer calories per foot. On a small lot, the honest goal may be all the family's vegetables plus a few weeks of potatoes, with stored grain and beans from the [pantry](/food-storage/how-much-food-to-store-for-a-family-of-four) carrying the rest.

Pick the sunniest ground you have. Mother Earth News sets six hours of full sun a day as the minimum, and more is better for potatoes, corn and squash. Plan water before you plan beds, too. A garden that depends on the municipal tap in a drought or an outage will be the first thing to go dry, and rain barrels or a well with a hand pump keep it alive.

### Seed you can save

A survival garden should be able to plant itself next year. That rules out most hybrids. [University of Illinois Extension](https://extension.illinois.edu/blogs/good-growing/2025-10-10-open-pollinated-vs-hybrid-important-distinction-when-saving-seeds) explains that hybrid seed, usually marked F1 on the packet, comes from controlled crosses and its offspring will not reliably carry the parent's traits. Open-pollinated and heirloom varieties do, so those are the ones to buy.

Some crops are easier to save than others. Illinois Extension lists tomatoes, peppers, peas and beans as self-pollinating and needing little or no special care for seed saving, which makes dry beans the ideal first seed crop: the seed you eat is the seed you plant. Squash, pumpkins, cucumbers and melons cross freely through insects, and the same page gives 1,300 feet as the minimum separation between squash varieties to keep them pure. Most backyards cannot manage that, so grow one variety per species, or hand-pollinate and bag a few flowers. Sweet corn needs nearly a mile of separation from other corn, and carrots and beets take two seasons to set seed, so save those later, once the easy ones are routine.

Potatoes are the exception to the seed rule, because they are planted from tubers. Saving your own seed potatoes works for a few seasons, but tubers carry plant disease from year to year, which is why commercial growers buy certified stock.

Keep a reserve of purchased seed as well, sealed in a jar in a cool dark place, for the year a crop fails or a saved line goes wrong. Lewis repeats an old gardener's rule that a third of your plants give a bumper crop, a third a fair one and a third nothing at all, and farm families once planned for double what they needed for that reason.

### Plan it on paper in January

The planning happens indoors, in the cold months, and it is the cheapest part of the work. Mother Earth News advises planning a garden on paper first, since it is better for it to fail on paper than in the ground. A workable winter list:

* Decide the share of calories the garden is meant to supply, and do the row math above for your family's size.
* Sketch the plot to scale, with paths, the sunniest beds for potatoes and corn, and the edges for squash.
* Order open-pollinated seed and certified seed potatoes early, before favorite varieties sell out.
* Find your last spring frost date and your hardiness zone through your county extension office, which also publishes planting dates for local crops.
* Line up compost, mulch, fencing against deer and rabbits, and a water source for August.
* Get a soil test from your extension office so you add lime or fertilizer to what the ground actually lacks.

Grow it this year, while the stores are still open. Gardening is a skill learned through failures, and a bad potato year is a lesson when the pantry is full and a disaster when it is the only food coming in.

### From the row to the pantry

A harvest that cannot be kept only feeds the family for a few weeks in fall. Plan the storage with the same care as the planting. Potatoes, carrots, beets, cabbage and onions go to a cold room, and our [root cellar guide](/homestead/how-to-build-a-root-cellar) gives the temperature and humidity each one needs. Dry beans go into sealed jars or buckets once they rattle in the pod. Winter squash cures in the sun for a week or two after picking and then sits on a shelf indoors.

Canning carries the rest. Green beans, corn, carrots and other low-acid vegetables must go through a pressure canner, and our guide to [pressure canning low-acid food](/homestead/pressure-canning-for-beginners) walks through the tested process. Winter squash is safest canned in cubes, because Clemson Extension notes there is no tested process for pumpkin or squash puree. Scraps, cull potatoes and spent bean plants go to a [laying flock](/homestead/backyard-chickens-for-eggs), which turns them into eggs and the eggs into protein the garden does not supply.

### My take: start with potatoes

If I were starting this spring with no garden at all, I would put in one 100-foot row of potatoes, half a row of dry beans and four hills of a butternut squash, and nothing else in the calorie part of the plot. That is a weekend of digging, it teaches the three skills that matter (hilling, drying, curing), and it ends the season with food that sits in the house through winter. I'd add a short bed of kale and onions beside it.

The second year I would double whatever did well and add a patch of flour corn if there is room. I would rather grow three crops well and know their yields on my own ground than plant twenty varieties and learn nothing from any of them.

The garden is a supplement for most households, and that is fine. Paired with a sealed pantry of grain and beans, it turns stored staples into meals worth eating and stretches them by months. More guides to producing and keeping food are in the [homestead section](/homestead).

### Survival garden questions

What should I plant first in a survival garden? 

Potatoes. They are forgiving for a beginner, they give the most food energy for the row space in most of the country, and a cool dark corner keeps them for months. Add dry beans and a winter squash once the potatoes are in.

Can a garden feed a family with no store food at all? 

Only on a large plot worked by people who already know how to garden. Ecology Action, which has studied small-plot food growing for decades, puts a complete diet at about 4,000 square feet per person at its intermediate yields. For most households the realistic goal is a share of the calories plus most of the vegetables.

Are survival seed buckets worth buying? 

Seed only feeds you if you can grow it, and a sealed bucket in a closet teaches nothing. Buy open-pollinated seed of the crops you plan to eat, plant it this season, and save your own from the varieties that do well on your ground.

Why grow dry beans if the yield is so low? 

For protein and for storage. A pound of dry beans carries roughly four times the calories of a pound of raw potatoes, keeps for years in a jar, and needs no cellar. The plants also return nitrogen to the soil.

When should I start planning next year's garden? 

Over the winter. Order seed in January or February before popular varieties sell out, sketch the beds, and line up compost and fencing so you can plant when the soil warms.
