If you’ve ever asked yourself, “How much do I need to plant to feed my family for a full year?”, you’re not alone. It’s one of the most common questions I get—and also one of the biggest sticking points for gardeners.
Because here’s what most of us do… We plant enough for fresh eating during the growing season. Maybe we preserve a little extra. But within a few months, it’s gone.
Meanwhile, on our homestead, we’ve been able to grow and store enough food that I haven’t bought onions, potatoes or tomato products from the store in years.
And no, it doesn’t take acres of land. What it takes is a simple shift in how you plan your garden. Let me show you exactly how to do it.

How Much to Plant for a Year’s Worth of Food (Quick Answer)
If you want a quick, practical answer, here it is: To figure out how much to plant for a year’s worth of food:
- Track how much of a certain crop or preserved food your family eats in one week
- Multiply that number by 52 weeks
- Divide by the average yield per plant
For example:
- Onions: 40–60 lbs per year (family of 4) → ~200–250 plants
- Potatoes: 100–150 lbs per year → ~20–40 lbs seed potatoes
This simple method works for any crop and takes the guesswork out of garden planning.
As we shared in Pioneering Today podcast episode #81 with my father (the podcast player is located at the top of this post) and in 17 Self-Sufficiency Tips from the Great Depression and 1940’s, almost all of the food they ate was what they grew and put up themselves. Knowing how to grow all your own food was crucial to survival.
These essential homestead skills used to be a way of life, planting and putting up your own food to see you through. It was how the pioneers did it.
Most of us aren’t relying completely on what we plant and preserve ourselves; we’re still supplementing with the grocery store. But what if you did have to survive on what you planted and preserved? How much money would it free up for you and your family?

How to Calculate How Much to Plant for a Year’s Worth of Food
This is the exact method I use every year on our homestead.
It’s simple, but it’s powerful.
Step 1: Look at What You Actually Eat
Start with one crop—onions, potatoes, carrots, anything.
Ask yourself:
👉 How much do we use in a typical week?
Be honest here. This is what makes the system work.
Step 2: Multiply by 52
Now take that weekly number and multiply it by 52 weeks.
That gives you your true yearly need.
Step 3: Match It to Plant Yield
Now figure out:
- How much each plant produces
- How many plants you need to meet your goal
That’s it.
Once you do this for a few staple crops, your entire garden plan becomes clear.
How Many Onions to Plant Per Person (Real Example)
For our first example, we’ll use onions. When you plant an onion seed (or onion start), it will only produce one onion per plant. So, the math is pretty simple, once you know about how many onions your family uses per year.
Let me show you what this looks like in real life.
For our family of four:
- Yearly need: 40–60 pounds of onions
- Plants needed: 200–250 onion plants
- Space required: Just two garden rows
That surprises most people.
But onions can be planted close together, which makes them incredibly efficient.
Onion Spacing:
- 4–6 inches apart
- Rows 12 inches apart
That means you can grow a full year’s supply in a small area.
Choosing Onion Varieties for Long-Term Storage
If your goal is to eat from your garden year-round, variety matters more than anything else.
Storage vs Sweet Onions
- Sweet onions (like Walla Walla):
- Incredible flavor
- Only store 4–5 weeks
- Storage onions:
- Designed to last months
- Essential for year-round use
My Go-To Storage Varieties:
- Patterson → stores up to 10–12 months
- Blush → stores 6–9 months
- Red Wing → stores 4–6 months
👉 I grow a mix and use the shorter-storage onions first.
Choose the Right Onion Type for Your Location
Where you live determines what you should grow:
- Northern climates → long-day onions
- Middle regions → intermediate-day
- Southern climates → short-day
If you plant the wrong type, you won’t get proper bulb formation.
How Many Potatoes to Plant Per Person
Let’s do another example with potatoes. Since they produce more than one potato per plant, this will be helpful when deciding how many plants to grow for those types of crops.
Now let’s look at potatoes.
For a family of four:
- Yearly need: 100–150 pounds
- Seed potatoes needed: 20–40 pounds
Potatoes multiply, which makes them one of the most efficient crops you can grow.
Determinate vs Indeterminate Potatoes
This is something many gardeners miss.
Determinate:
- Produce all at once
- Lower total yield
Indeterminate:
- Continue producing
- Can be hilled for higher yields
- Best for maximizing production
Best Potato Varieties for Storage
If you want potatoes to last through winter, choose storage varieties:
- German Butterball (my favorite)
- Russet
- Yukon Gold
👉 Red potatoes and fingerlings are great, but don’t store as long.
Always Use Seed Potatoes (Here’s Why)
It might be tempting to plant grocery store potatoes, but I don’t recommend it.
- They’re not certified disease-free
- They can introduce blight into your soil
- That disease can stick around for years
👉 Start with certified seed potatoes, then save your own later.
What size garden to feed a family of 4 for a year?
Our main annual vegetable garden space is a 20 x 30-foot rectangular bed. We have a 10 x 20-foot high tunnel where I grow all of our tomato plants.
We also have another 20 x 20-foot garden bed and three 3×20-foot rows for corn.
Your yield per plant can vary by type and growing season, but this is our average and typical yield.
How Much to Plant Per Person (Quick Reference)
To determine how much to plant for a year’s worth of food, multiply your family’s weekly consumption by 52 to get your annual need, then divide by the average yield per plant.
For example:
- If your family eats 2 pounds of potatoes per week:
2 × 52 = 104 pounds per year - If each plant yields 3–5 pounds:
You would need approximately 25–35 potato plants
This same formula works for onions, tomatoes, and any other crop.
| Crop | Amount to Plant Per Person | Amount to Plant for Family of 4 | Planting Notes | Approx. Space Needed |
|---|---|---|---|---|
| Bush Beans | 2–3 lbs (dry) | 8–12 lbs (dry) | Direct seed. Great for canning or freezing. | 16–20 sq ft |
| Pole Beans | 3–4 lbs (dry) | 12–16 lbs (dry) | Higher yield than bush beans. Use trellis or poles. | 20–25 sq ft |
| Brassicas (broccoli, cabbage, cauliflower, kale, etc.) |
10–12 plants | 40–48 plants | Transplant. Cool-season crops that store well. | 40–60 sq ft |
| Corn | 20–25 plants | 80–100 plants | Plant in blocks for best pollination. | 100–150 sq ft |
| Cucumber | 2–3 plants | 8–12 plants | Great for fresh eating and canning. | 10–15 sq ft |
| Garlic | 12–15 cloves | 50–60 cloves | Plant individual cloves in fall for summer harvest. | 15–20 sq ft |
| Onion | 50–60 plants | 200–250 plants | Store well for year-round use. Use storage varieties. | 20–30 sq ft |
| Peas | 20–30 plants | 80–120 plants | Plant early for best yield. Use trellis for peas. | 15–20 sq ft |
| Peppers | 3–5 plants | 12–20 plants | Includes bell, jalapeño, poblano, etc. | 15–20 sq ft |
| Potatoes | 5–10 lbs seed potatoes | 20–40 lbs seed potatoes | High-yield crop. Store in cool, dark place. | 50–100 sq ft |
| Tomatoes | 2–3 plants | 8–12 plants | Great for fresh eating and canning. | 15–20 sq ft |
| Summer Squash | 1–2 plants | 4–8 plants | Zucchini, yellow squash, etc. | 10–15 sq ft |
| Winter Squash | 1 plant | 4 plants | Butternut, acorn, spaghetti, etc. Long storage life. | 20–30 sq ft |
- Amounts are general guidelines and will vary based on your family’s eating habits, the varieties you grow, and growing conditions.
- Focus on storage varieties for crops you plan to keep and use all year.
There are five crops I grow for our family that I never (yes, never) buy from the store anymore. They are onions, potatoes, carrots, beans and squash (both summer and winter).
Growing enough food for your family for a year doesn’t mean you’re growing everything. I means you’re reducing your reliance on the grocery store for specific crops that grow well in your region.
I’m never going to be able to grow my own sugar cane, vanilla beans or wheat. This isn’t about eliminating the grocery store, but rather thinking through specific crops that we can eliminate from our grocery list.
Harvesting & Curing for Maximum Storage
| Crop | When to Harvest (Key Signs) | How to Harvest | Curing (If Needed) | Storage Tips & Length |
|---|---|---|---|---|
| Bush Beans | Pods are full but still tender. Beans are plump but not bulging. | Pick by hand or cut with scissors. | Not needed. | Refrigerate 7–10 days or can/freeze for 8–12 months. |
| Pole Beans | Pods are full and firm. For dry beans, let pods dry on the plant. | Pick or cut, then shell for dry beans. | Not needed. | Fresh: refrigerate 7–10 days. Dry beans: store in airtight container 1–2 years. |
| Brassicas (broccoli, cabbage, cauliflower, kale, etc.) |
Heads are firm and tight. Harvest before yellow flowers appear. | Cut heads or leaves with a sharp knife. | Not needed. | Refrigerate 1–2 weeks. Some, like cabbage, store 2–4 months in a root cellar. |
| Corn | Silks are brown and dry. Kernels are plump and milky. | Cut ears from the stalk. | Not needed. | Refrigerate 2–5 days or freeze up to 12 months. |
| Cucumber | Firm and fully colored. Best when 6–8 inches long. | Cut or twist from the vine. | Not needed. | Refrigerate 7–10 days or can/pickle for 1 year. |
| Garlic | Lower leaves turn brown, usually in late spring or early summer. | Pull from the ground. | Cure 2–4 weeks in a warm, dry, well-ventilated place. | Store in a cool, dry place for 6–10 months. |
| Onion | Tops fall over and begin to dry. Wait until 50–80% are down. | Pull from the ground. | Cure 1–2 weeks in a warm, dry, well-ventilated place. | Store in a cool, dry, dark place for 6–12 months. |
| Peas | Pods are plump and tender. For shelling peas, pick before peas get too large. | Pick pods. | Not needed. | Refrigerate 5–7 days or freeze up to 12 months. |
| Peppers | Fully colored and firm. | Cut with scissors or twist from plant. | Not needed. | Refrigerate 1–2 weeks or freeze up to 12 months. |
| Potatoes | Plant tops die back. Wait 1–2 weeks after foliage dies. | Dig carefully with a fork or shovel. | Cure 1–2 weeks in a cool, dark place (50–60°F) with high humidity. | Store in a cool, dark, slightly humid place for 3–6 months. |
| Tomatoes | Fully colored and slightly soft to the touch. | Pick gently. | Not needed. Allow to ripen at room temperature if needed. | Store at room temperature 3–7 days. Can or freeze for up to 12 months. |
| Summer Squash (zucchini, yellow squash, etc.) |
Small to medium size. Skin is tender and glossy. | Cut with knife or twist off. | Not needed. | Refrigerate 1 week or freeze up to 12 months. |
| Winter Squash (butternut, acorn, spaghetti, etc.) |
Rind is hard and cannot be pierced with a fingernail. Stem is dry and corky. | Cut from vine leaving a 2–3 inch stem. | Cure 10–14 days in a warm, dry place (80–85°F). | Store in a cool, dry place at 50–60°F for 3–6 months. |
- Harvest in the morning for best flavor and crispness.
- Handle produce gently to avoid bruising.
- Cure crops properly, especially onions, garlic, potatoes, and winter squash, for longer storage life.
- Store crops in the right conditions. Cool, dark, and dry is key.
It’s important to know when and how to harvest crops for maximum storage. For example, with onions, you harvest them when 50-80% of the tops fall over.
Beyond harvesting, certain crops need to be properly cured for them to be stored long-term. For onions, cure them in a dry, well-ventilated area, out of direct sunlight. You allow them to dry/cure until the stems/stalks are completely dry and crispy. Learn how to harvest, cure and string onions here.
Refer to the graphic above for various crops.
In summary, to grow a years worth of food, you simply need to track your weekly food usage for your family, multiply by 52, choose high-yield, storage crops, grow the correct varieties for your region and cure and store properly.
👉 This is how you move from gardening for fun to gardening for real food security.
Troubleshooting Common Storage Problems
Why are my onions rotting in storage?
This is usually caused by improper curing or too much moisture. Onions must be fully dried before storing.
Why are my potatoes turning green?
Exposure to light causes potatoes to produce solanine, which turns them green and makes them bitter.
Why didn’t my onions form bulbs?
This is often due to planting the wrong day-length variety for your region.
FAQs
Track weekly use, multiply by 52, then divide by plant yield.
