The 80/15/5 Rule
I am 100% convinced we can grow our own food without industrial agriculture, and that in the doing of it we need not suffer or struggle to make it reality.
The evidence is plain: every generation before the last three grew their own food. The knowledge isn't lost. It's just not being used.
What follows is a framework and a timeline. The framework is the 80/15/5 rule: how you allocate your growing space. The timeline is five years: how you get from zero to subsistence. The plan assumes you have access to land. Not ownership. Access. A backyard, a community plot, a neighbor's field, a leased acre. The plan also assumes you're starting from wherever you are. The sequence works regardless.
The only prerequisite is willingness to observe before you act, and patience with perennials that take time.
The Framework: 80/15/5
80% staple calories. Potatoes, wheat, rye, beans, corn, sunflowers. These keep you alive. They store for months or years. They're not sexy. They're essential. Every square foot you give to a staple crop is a square foot that's working toward your independence.
15% perennials. Fruit trees, nut trees, berry bushes, asparagus, rhubarb. These take time to produce but pay dividends for decades. An apple tree produces fruit for fifty years. A chestnut tree produces for a hundred. A well-managed asparagus bed produces for twenty. The perennials are the long game. Plant them first because every year you wait is a year you don't harvest.
5% kitchen garden. Fresh vegetables for flavor and nutrition. This is where you experiment with varieties, techniques, and timings that you'll scale up later. The kitchen garden feeds you today. The staples feed you through the winter. The perennials feed you for decades.
The 80/15/5 framework is a design principle, not a rigid formula. Your exact ratios depend on your bioregion, your household size, your growing conditions, your preferences. The experimentation happens in the 5%. The results feed back into the 80% and the 15% over time.
The Principle: Observation Before Intervention
Every year of this plan begins with the same instruction: look at your land. Walk it in every season. Watch where water flows after rain. Watch where frost settles. Watch what grows without planting. Watch where the sun falls at noon in June and noon in December. Map it. Write it down.
The land has been running its own systems for four billion years. It knows things you don't. Your job in year one is mostly listening. Observation is the most active thing you can do, because every hour you spend watching saves you ten hours of doing the wrong thing. A swale built where water naturally flows is free irrigation. A swale built where water doesn't flow is a ditch.
Your Bioregion Determines Your Staples
Before you plant anything, answer this question: what grows here? Not what you want to grow. What the land wants to grow. What's already growing without your help. What grows in your bioregion that your neighbors have been growing for generations. What the indigenous people of your area grew before industrial agriculture showed up.
Your bioregion determines your staples. If you're in the Appalachian Foothills (Zone 6), your staples are wheat, rye, potatoes, beans, corn for grinding, and sunflowers for oil. If you're in the Pacific Northwest, your staples include different grain and bean varieties suited to a wetter, milder climate. If you're in the Desert Southwest, your staples include amaranth, tepary beans, and sorghum. The framework is universal. The specific crops are bioregional.
Year One: Observe and Plant
The goal: Start building your soil, plant your perennials, acquire your animals, and feed yourself whatever you can from what's already there.
You're not trying to feed yourself from your land in year one. You're trying to learn your land, build the foundation everything else stands on, and get perennials in the ground because they need years to produce. Every year you wait to plant a fruit tree is a year of fruit you don't get. Plant them now.
Plant perennials
This is the year-one priority that isn't optional. Fruit trees, nut trees, berry bushes, asparagus, rhubarb. These take one to five years to produce. If you wait until year three to plant them, you're starting your perennial production in year eight instead of year five.
- Fruit trees: apples, pears, peaches, plums, cherries. Plant in spring or fall. Mulch heavily. Water through the first season. After that, they're on their own.
- Nut trees: chestnuts, walnuts, hazelnuts. These take the longest to produce (5 to 10 years for full production) but produce the most calories per acre of any food. Chestnuts are the staple nut. They're the "grain that grows on trees." Hazelnuts produce faster (3 to 5 years) and provide both food and oil.
- Berry bushes: raspberries, blackberries, blueberries, strawberries. These produce in year one or two. They're the 15% that gives you something to eat while the trees mature.
- Asparagus and rhubarb: plant once, harvest for decades. Asparagus takes two to three years to produce. Rhubarb produces the first year. Both are perennials that earn their space every year after establishment.
Acquire animals
Ducks and chickens. Not because they're cute (they are). Because they're integrated fertility systems. Ducks eat slugs and produce manure. Chickens scratch and aerate soil, eat pests, produce manure, and both produce eggs (protein and fat). The eggs alone justify their existence. The manure makes them essential.
Start with a small flock: 6 to 12 laying hens and 4 to 6 ducks. You don't need a fancy coop. You need predator protection and water. The manure from 12 birds produces enough nitrogen to fertilize a substantial garden. Chickens on a spent bed will till it, eat pests, and fertilize it in one pass. This is the closed loop. The animals eat the crop residues. The manure feeds the next crop. The eggs feed you. The system works because nothing is wasted.
Grow what you can from what you have
In year one, plant annual staples in whatever space is ready. Potatoes, beans, and wheat are your priority crops. They're easy to grow, calorie-dense, and store well. Use the 80/15/5 framework: 80% of your space goes to staple calories, 15% to the perennials you just planted, 5% to a kitchen garden for fresh vegetables.
But don't force it. If your soil isn't ready, if you're still learning the land, if you need to build beds and add compost before you can plant, that's the work of year one. A poor planting in bad soil will discourage you. Good soil preparation will feed you for years.
Year Two: Plant the 80/15/5
The goal: Plant staple crops in easy-to-grow spaces following the 80/15/5 framework. Modify spaces that aren't yet productive. Start eating from your land.
Year two is when you start producing calories. You've observed the land. You've planted the perennials. You've got animals producing manure and eggs. Now you use every space you can to grow staple calories.
Modify spaces to make them productive
Year two is about finding spaces that aren't producing and making them produce. This is where observation pays off.
- Lawns: Convert to growing space. Sheet mulch (cardboard, compost, mulch) over grass in fall. Plant into it in spring. A suburban lawn is 5,000 to 10,000 square feet of potential staple crop production.
- Slopes: Terrace or swale. Terraces turn eroding hillsides into productive growing space. Swales slow water, build soil, and can be planted with fruit trees on the berm.
- Wet areas: Don't fight them. Plant water-loving crops. Rice, cranberries, watercress, willow for baskets and structure. Or dig a pond and stock it with ducks.
- Shade: Plant shade-tolerant crops. Mushrooms, ramps, wild ginger, hostas (yes, the ornamental, the young shoots are edible), elderberry.
- Edges: The most productive zones in any landscape are the edges where different systems meet. The edge of a field and a forest, the edge of a pond and a meadow. Plant these first. They produce more per square foot than either system alone.
- Problem areas: Compacted soil? Pigs will dig it up. Eroding hillside? Swales and terraces. Too wet? Pond and water crops. Too dry? Drought-tolerant staples (sorghum, amaranth) and swales to capture every drop of rain.
Year Three: Scale and Expand
The goal: Grow all the food from year one in spaces modified in year two. Expand 80% staple production into the space you farmed in year two. You're now eating significantly from your own land.
This is the inflection year. Years one and two were foundation. Year three is where the system starts producing enough that you can feel it. Your staple crops from the year-one spaces are producing reliably. Your perennials from year one are starting to yield. The spaces you modified in year two are now ready for serious production.
This is also the year to start seed saving in earnest. You've grown varieties for two years. You know which ones produce well in your conditions. Save seed from your best plants. This is the beginning of a locally adapted seed bank that will only get stronger with every generation. Every seed you save is an act of sovereignty.
Year Four: Complete the Food System
The goal: Fill every available growing space. Plant all staple crops for subsistence. Continue variety experimentation. Your food system is nearly complete.
By year four, you should be running out of lawn to convert and slopes to terrace. Good. That means you've used what you have. Now look for the spaces you haven't planted yet:
- Vertical space: Trellises for beans, cucumbers, grapes. Espalier fruit trees along fences.
- Containers: Buckets, tubs, grow bags on patios and driveways. Potatoes grow exceptionally well in containers.
- Window boxes and balconies: Herbs, greens, cherry tomatoes. Every calorie counts.
- Roof space: If you have flat roof access, container gardens work. Consider microgreens for high-nutrition, low-space production.
- Community connections: Neighbors with unused space. Trade produce for growing rights. This is where mutual aid becomes food production.
Calculate: how many calories does your household need per day? How many calories does each crop produce per square foot? Do the math. If you're short, plant more of the highest-calorie crops (potatoes, wheat, sunflowers). If you're long, experiment.
Year Five: Complete, Rotate, Repeat
The goal: Your food system is complete. Rotate crops, save seeds, improve soil, and repeat. The system now runs on its own terms.
Year five is not the end. It's the beginning. The five-year plan gets you to a functional subsistence food system. The next fifty years are about improving it.
You have:
- Staple crops producing enough calories to feed your household through the year
- Perennial fruit and nut trees producing annual harvests that increase each year
- Animals integrated into the system for fertility, pest control, and protein
- A seed bank of locally adapted varieties that improves every generation
- Storage and preservation systems (root cellar, drying, canning, fermenting) that carry harvest through winter and beyond
- Soil that's improving every year because you're returning more to it than you take
- The knowledge and skills to maintain and improve all of the above
Crop rotation is now second nature. You're rotating by family: nightshades, legumes, brassicas, grains, cucurbits. You're integrating animals into the rotation: chickens on spent beds, pigs on root crop aftermath, ducks in the wet areas. You're saving seed from your best plants and discarding varieties that don't perform. You're experimenting with new varieties in the 5% kitchen garden and scaling successful experiments into the 80%.

The Hard Truth About Perennials
The perennials you plant in year one will not feed you in year one. The apple tree will produce its first real crop in year three or four. The chestnut will produce in year five to seven. The asparagus will be ready to harvest in year three. The berries will produce small yields in year two and full yields by year three.
This is the design. It is not a flaw. Perennials take time because they're built to last. An apple tree will produce fruit for fifty years. A chestnut tree will produce for a hundred. A well-managed asparagus bed will produce for twenty. The investment compounds. But you have to make the investment first.
That's why year one is perennial planting year. Not because you'll eat from them in year one. Because if you don't plant them in year one, you won't eat from them in year four. The annuals will feed you while the perennials mature. The 80/15/5 framework accounts for this. The 80% (staples) are mostly annuals. The 15% (perennials) take time. The 5% (kitchen garden) gives you something fresh to eat right away.
Every year you delay planting a fruit tree is a year of fruit you don't get. Plant it now. Water it through the first season. Mulch it. Protect it from deer. Then let it grow. It will outlast you. That's the point.
The Closed Loop in Practice
This isn't just about growing food. It's about closing loops. Every output becomes an input. Every waste becomes a resource. The system runs on its own terms, not on terms set by markets, corporations, or supply chains.
- Crop residues become animal feed or compost. The wheat straw feeds the animals or becomes compost. The corn stalks become mulch. The bean vines go to the compost pile. Nothing is wasted.
- Animal manure becomes fertility. Chickens on spent beds till and fertilize in one pass. Ducks on ponds produce nutrient-rich irrigation water. The animals are tools. Their manure is the fuel.
- Kitchen scraps become compost. Everything organic goes back to the soil. Vegetable trimmings, eggshells, coffee grounds, tea leaves. The compost pile is the bank where you deposit soil wealth and withdraw fertility.
- Seed saving becomes sovereignty. Every seed you save is a seed you don't have to buy. Every locally adapted variety is a variety that performs better in your conditions than anything from a catalog. Your seed bank gets stronger every year. The seed companies get weaker every year.
- Water becomes managed. Swales slow runoff and build soil. Ponds store water for dry periods. Rainwater catchment irrigates without pumps. Every drop is used at least once before it leaves the system.
- Energy becomes appropriate. Hand tools instead of power tools. A sharp scythe mows an acre of grain. The appropriate technology principle: use the lowest-energy tool that does the job. Not because energy is bad. Because independence is good.
The closed loop is the argument. You can't argue with a full pantry. You can't argue with a soil test that shows increasing organic matter. You can't argue with a food system that produces more each year with fewer external inputs. The farm is the argument. The full belly speaks.
Beyond Food: The Whole Withdrawal
The five-year food system is the foundation, the bedrock everything else stands on. Once you're producing your own calories, you've removed the primary lever of control. But the extraction economy has other levers: your energy, your tools, your money, your community, your governance.
That's why the food system sits at the beginning. It's what makes everything else possible. A community that can feed itself can strike. A community that can't, can't. A family that can feed itself can say no to a bad job. A family that can't, can't. Food first. Then tools. Then community. Then economics. Then technology. Each layer builds on the one before it. Each layer makes the next one possible.
But the sequence also runs in parallel. You don't wait until year five of your food system to start building community. You start the mutual aid group in year one. You don't wait until your pantry is full to start reducing financial dependence. You cut the first subscription in year one. The five-year food system is the spine of the Withdrawal. The other systems wrap around it, supporting it and supported by it.
It starts with food. It doesn't end there.
