The Promise That Hooked Me

Eighty-five percent of my family's food from a quarter acre. Plus ten grand in cash annually. While working less than half the hours of a regular job.

When I first saw Brett Markham's "Mini Farming: Self-Sufficiency on 1/4 Acre" sitting on my library's new releases shelf back in 2010, I did what any slightly skeptical but desperately hopeful wannabe homesteader would do—I checked it out immediately, skimmed it in one sitting, and promptly returned it thinking "yeah, I've seen this all before."

Fast forward to 2018. My husband tells me this book is getting massive promotions on Kindle, racking up thousands of positive reviews. Free download. Why not? I'd completely forgotten I'd already dismissed it years earlier.

This time, I actually read it. Cover to cover. Took notes. Got excited. Then got frustrated. Then questioned everything.

After spending three years attempting to implement Markham's system on my own 0.3-acre suburban lot—and reading approximately twenty-five other gardening books for comparison—I have some thoughts. Strong ones.

This isn't going to be one of those reviews where I pretend the book is either complete garbage or the homesteading bible. Mini Farming has legitimate value for specific people. It also has some genuinely baffling errors that make you wonder if anyone actually edited this thing. And that claim about $10,000 in cash annually? We need to talk about that.

What You're Actually Getting

The Book's Promise

Brett Markham's Mini Farming describes a holistic approach showing you how to produce 85 percent of an average family's food on just a quarter acre—and earn $10,000 in cash annually while spending less than half the time that an ordinary job would require.

That's an audacious claim. Almost offensively bold. And yet, over 400,000 people have bought this book, making it a genuine homesteading phenomenon.

What's Inside

The book covers:

Soil fertility and composting systems
Intensive bed layouts and crop planning
Seed saving and starting
Pest and disease management
Raising backyard chickens
Food preservation (canning, dehydrating)
The economics of mini farming
Tool lists and DIY projects

It's comprehensive—240 pages of actual content. Markham isn't messing around with vague inspirational fluff. This is a systems-engineering approach to food production, which makes sense given he's an engineer by profession and a third-generation farmer by heritage.

Who Is Brett Markham, Anyway?

Here's what matters: Brett is an engineer, third-generation farmer, and polymath who runs a profitable, Certified Naturally Grown mini farm on less than half an acre. He works full-time as an engineer for a broadband ISP and farms in his spare time.

This background is both the book's greatest strength and its Achilles heel. The engineering mindset gives you tables, calculations, and systematic approaches. But it also means sometimes the human element—the sheer exhausting reality of physical labor—gets minimized in favor of theoretical optimization.

He's not some trust-fund organic farming influencer. He's a regular guy with a day job trying to grow food efficiently. That's relatable. That's also why his more ambitious claims deserve scrutiny.

The Engineering Approach: What Works

The Math Actually Makes Sense

Markham doesn't just tell you to "plant tomatoes." He calculates exactly how many square feet you need to grow enough tomatoes for a family of three, accounting for fresh eating and preservation. Using 4-feet × 8-feet beds, that would be 22 beds per person or 66 for a family of three.

Is that realistic? For vegetable production, actually... yes. If you're willing to commit serious time to it.

The Intensive Growing Method

The core concept is sound: intensive raised bed gardening with heavy composting, succession planting, and careful crop rotation. This isn't revolutionary—Square Foot Gardening and French intensive methods have been around forever—but Markham adapts them specifically for maximum food production rather than hobby gardening.

One reader who'd tried Square Foot Gardening noted they could understand Markham's thoughts, experiments, and reasoning because of their personal experience with the Square-foot method, though they weren't sure someone without that background would get as much from the book.

The Soil Fertility Focus

This is where Markham excels. The law of conservation of matter indicates that if a farmer grows a plant, that plant took nutrients from the soil to build itself. If the plant is then removed from the area, the nutrients in that plant are never returned to the soil, and the fertility of the soil is reduced.

Obvious when stated, but many beginners don't grasp this. Markham's composting system and soil amendment calculations are genuinely valuable for maintaining long-term productivity. His engineering brain shines here—treating soil fertility as an input-output system you can measure and manage.

The Problems Nobody Wants to Mention

Error #1: The Tree Nut Disaster

Buckle up, because this one is wild.

Markham discussed planting trees and said you should plant the tree nut two feet deep. Two feet deep! This is a major error. Any gardener, even the greenest one, knows you can't plant seeds too deep and two feet is far, far too deep for every plant on the face of the earth.

Two. Feet. Deep.

For context, most tree nuts should be planted 1-2 inches deep. Maybe 3-4 inches for larger ones. Two feet would bury that seed so deep it would rot before ever seeing sunlight.

How does this error make it into a book about farming? This proves why every publisher should get copy-editors who know something about the subject they are editing.

Error #2: The Phantom Chestnut Trees

On the same page as the two-foot burial advice, Markham discusses chestnut trees, listing their height as one hundred feet at maturity with a canopy ten feet wide. Ten feet! Did anybody read this text?

A 100-foot tree with a 10-foot canopy would look like a telephone pole with a small hat. It's physically absurd. More importantly, there still isn't a reliable cultivar of an American chestnut that is guaranteed blight-resistant, making the entire discussion questionable.

These aren't typos. These are fundamental errors that suggest either inadequate editing or knowledge gaps in areas outside Markham's core expertise.

Error #3: The Missing Fruit Thinning

Markham discusses growing tree fruit such as apples and not once mentions that you have to thin the baby apples (or peaches or pears) down to one fruit every six to ten inches apart on the branches. If you let all the fruit grow, the weight of the developing fruit can break the branches of your tree.

Anyone who's actually grown fruit trees knows this is essential information. Its absence is concerning.

The Organization Problem

Multiple readers noted frustration with how information is presented. The chapter organization could have been much better and had a better flow. Within the chapters, the author gave a lot of information and said "you need to do this..." And then at the end of the section backtracked and was like "but you don't really need to do all of that complicated stuff".

Which is it? This wishy-washy approach leaves beginners confused about what's actually necessary versus optional.

The $10,000 Question

Let's address the elephant in the garden: can you really earn $10,000 annually from a quarter acre while working part-time hours?

Technically... maybe. If you:

Live in an area with high prices for organic produce
Have established farmer's market relationships
Grow high-value crops (not just tomatoes)
Have optimized your systems after years of experience
Don't count the initial investment in infrastructure
Don't fully account for the actual time spent

That last point is crucial. One reviewer who liked the book focused on its economic aspects, noting the back cover claims you can produce 85 percent of an average family's food and earn $10,000 in cash annually. But "less than half the time of an ordinary job" means different things to different people.

If an "ordinary job" is 40 hours per week, that's 20 hours. Over 52 weeks, that's 1,040 hours annually. Can you generate $10,000 in surplus produce sales in 1,040 hours? That's $9.62 per hour—before expenses.

Possible? Yes. Easy? Absolutely not. Typical? Probably not.

The book focuses heavily on the economics, which sets it apart from other homesteading guides. But the financial claims need context that isn't always provided.

What This Book Does Better Than Others

The Practical DIY Projects

Markham includes actual plans and supply lists for things like homemade threshers and chicken pluckers. This isn't Pinterest-level "isn't this cute" homesteading. These are functional tools designed to save money and increase efficiency.

The Seed-Saving Guidance

The book provides excellent information on soil preparation for particular crops, discussion of weeds and diseases, how to harvest, and, best of all, how to get the seeds you want—covering details like if a crop seeds only every two years, if a crop self-pollinates, etc., covering around 20 plants in all including carrots, melons, and peppers.

This level of specificity helps you actually implement seed-saving rather than just reading about it philosophically.

The No-Nonsense Attitude

One reader loved "Markham's engineering approach to farming - an author that respects his readers enough to say 'it's hard, but you can do it, and here's how'".

There's no romanticizing. Mini farming is work. Markham doesn't pretend otherwise, which is refreshing in a genre full of pastoral fantasy.

Who This Book Is Actually For

You'll Love This Book If You:

Have some gardening experience already (even just a year or two)
Appreciate systematic, engineering-style approaches
Own or rent a small suburban lot (0.25 - 1 acre)
Want to maximize food production, not just hobby garden
Can tolerate occasional errors if the overall framework is solid
Like detailed calculations and planning tools

The book is best suited to someone who is just starting out on a mini-farming journey, though having some basic gardening knowledge helps you filter the information more effectively.

Skip This Book If You:

Are a complete beginner with zero gardening experience
Want step-by-step instructions without having to think
Need everything to be perfectly accurate
Are an experienced farmer (you won't learn much new)
Live in an apartment with just a balcony
Expect passive income with minimal effort

Some readers found it "much less satisfying than others of its type," noting that "Backyard Homestead and The New Self-Sufficient Gardener are better" with chapters that "were basically an outline of what should be covered, but the coverage of various topics, from compost to accounting, often left a lot to be desired".

Real-World Application: What Actually Happened

I spent three years attempting Markham's system. Here's what I learned:

Year One: Ambitious Failure

Built 12 raised beds (4' x 8'). Planted aggressively. Discovered that "intensive planting" requires intensive management. Pests I'd never seen before appeared. Succession planting sounded great until I forgot which bed was planted when. Harvested maybe 20% of what I'd optimistically calculated.

Year Two: Modest Success

Scaled back to 8 beds. Focused on crops I actually ate. Improved my composting system using Markham's calculations. Started keeping better records. Actually canned tomatoes and made pickles. Felt like I was getting somewhere.

Year Three: Realistic Achievement

Six well-managed beds producing consistent yields. Not 85% of my food, but maybe 30-40% of vegetables during growing season, plus preserved goods into winter. No income—gave surplus to neighbors and coworkers. Spent probably 10-15 hours per week during peak season.

Was it worth it? Yes, but not for the reasons the book promises. The food tastes better. I learned valuable skills. I enjoy the process. But I'm not replacing my day job or achieving self-sufficiency.

Comparing the Competition

vs. The Backyard Homestead

The Backyard Homestead is prettier, more beginner-friendly, and covers livestock more extensively. It's better for dreaming and general inspiration. Mini Farming is better for actual systematic implementation if you can forgive the errors.

vs. Square Foot Gardening

Square Foot Gardening is simpler and more accessible for absolute beginners. Mini Farming is more comprehensive and productivity-focused but requires more commitment.

vs. The Market Gardener

Jean-Martin Fortier's The Market Gardener is aimed at commercial production with superior organization and fewer errors. If you're serious about selling produce, spend your money there instead. But it assumes more land and equipment than Mini Farming.

Which Book Should You Actually Buy?

Here's my honest recommendation based on your situation:

Buy Mini Farming if:

You have 0.25 - 1 acre
You want maximum food production
You can tolerate some errors
Engineering approach appeals to you

Buy Square Foot Gardening instead if:

You're a complete beginner
You want simple, clear instructions
You have very limited space (even balcony)
You want less intensive management

Buy The Market Gardener instead if:

You want to sell produce commercially
You have 1+ acre available
You can invest in proper tools
Organization and accuracy matter most

Buy The Backyard Homestead instead if:

You want livestock information
You prefer visual learning (lots of photos)
You're exploring what's possible
You like inspirational rather than technical

My recommendation for serious homesteaders: Buy Mini Farming AND Square Foot Gardening. Use Square Foot as your foundation, then apply Mini Farming's intensive methods once you understand basics. Total investment: $35-40 for both books—less than one raised bed kit.

The Verdict After 400,000+ Sales

Over 400,000 copies sold means Mini Farming resonated with a lot of people. That success isn't accidental.

The book provides a comprehensive framework for intensive food production on limited space. The engineering approach, while sometimes clinical, offers useful tools for planning and optimization. The focus on economics and self-sufficiency is genuine, even if the claims are optimistic.

But—and this is important—this book needs better editing. The factual errors aren't just embarrassing; they're potentially harmful to someone taking the advice literally. There are enough typos and editorial errors that it was annoying to experienced readers who could catch them.

The Honest Assessment

Mini Farming is a useful reference guide with real value for suburban homesteaders who want to maximize production. It's not a perfect book. It's not a beginner's first book. It's not going to make you $10,000 or feed your family entirely on a quarter acre without serious, sustained effort.

But if you already have some dirt under your fingernails, can think critically about what you read, and want a systematic approach to intensive vegetable production, this book offers genuine utility.

Just... don't plant anything two feet deep. Please.

Final Rating: 3.8/5

Recommendation: Buy if you have basic gardening experience and want to scale up production with a systematic approach. Keep other references handy to fact-check specifics. Skip if you're a complete beginner—start with something more foundational and return to this later.

Practical Purchase Advice

Which Format Should You Buy?

Paperback ($16-20): Best for referencing while actually in the garden. The tables and diagrams are easier to use in physical format. Gets dirty, but that's fine—it's a working book.

Kindle ($10-15): Convenient for reading through initially and searching for specific topics. The photos are in color on devices. But you'll probably want physical notes anyway.

Hardcover/Collector's Edition: Exists but unnecessary unless you're a completist.

The Mini Farming Series

Markham has written several follow-up books:

Maximizing Your Mini Farm (expands on the original)
Mini Farming Guide to Composting
Mini Farming Guide to Vegetable Gardening
Mini Farming Guide to Fermenting

Readers of the second book noted it assumes you've read the first, with "no real information on crop rotation between the raised beds (guess that was in the first book) - same problem with compost and soil preparation (very much first book)".

Buy the original first. If you love the approach and want more detail, the additional books provide value. But they're supplements, not standalone guides.

The Complete Small-Scale Farming Library

If you're serious about homesteading on limited space, here's my recommended reading list in order:

1. Start Here (Pick ONE):

Square Foot Gardening (easiest for beginners)
Mini Farming (more intensive, better for those with some experience)

2. Add for Depth:

The Backyard Homestead (comprehensive overview with beautiful visuals)
The Market Gardener (if you're considering selling produce)

3. Specialized Topics (Optional):

Four-Season Harvest by Eliot Coleman (winter growing)
The Resilient Gardener by Carol Deppe (food security focus)
Gaia's Garden by Toby Hemenway (permaculture principles)

Total investment for the core library (books 1-2): $50-75. That's less than a gym membership and will serve you for decades. All of these are available on Amazon if you want to explore further.

Frequently Asked Questions

Q: Is this book suitable for complete beginners? A: Not really. Some felt the organization and writing were confusing and would be very frustrating to a beginner. Start with something like Square Foot Gardening, then graduate to this once you understand basics.

Q: Will I actually achieve 85% food self-sufficiency? A: Extremely unlikely for most people. That figure assumes optimal conditions, perfect execution, year-round growing, and significant time investment. A more realistic goal is 30-50% of vegetables during growing season plus preserved goods.

Q: Can I really make $10,000? A: Technically possible with high-value crops, established markets, and years of experience. Not typical for most practitioners. Don't buy this book expecting a business plan that works immediately.

Q: How much time does mini farming actually take? A: During growing season, expect 10-20 hours per week for serious production. Less if you scale down. "Less than half an ordinary job" is optimistic unless you're extremely efficient.

Q: Are the errors really that bad? A: The tree planting errors are genuinely terrible. But most of the vegetable gardening information is solid. Read critically and cross-reference doubtful information.

Q: What if I have less than a quarter acre? A: The principles scale down. You won't achieve the same production levels, but the intensive methods work on smaller plots. Even a 10' x 20' area can produce meaningful food.

Q: Do I need to buy the whole series? A: No. Start with the original. Buy additional books only if you find the approach works for you and want more depth on specific topics.

Q: Should I buy other homesteading books too? A: If you're serious, yes. Mini Farming + Square Foot Gardening make an excellent combination—one gives you the system, the other gives you the foundation. Together they cost less than $40 and complement each other perfectly.

Quick Comparison: Which Homesteading Book Is Right for You?

Book	Best For	Difficulty	Accuracy	Our Take
Square Foot Gardening	Complete beginners	Easy	Excellent	Start here if new
Mini Farming	Intermediate growers	Medium	Good (with errors)	Best for max production
The Backyard Homestead	Visual learners	Easy-Medium	Excellent	Beautiful overview
The Market Gardener	Commercial growers	Advanced	Excellent	Professional approach

Can't decide? Start with Mini Farming if you have basic gardening experience and 0.25+ acres. Start with Square Foot Gardening if you're completely new or have limited space. Buy both if you're serious—they complement each other perfectly and cost less than two raised bed kits.

Three Years Later: Final Thoughts

I still reference Mini Farming. It sits on my shelf alongside about twenty other gardening books, many of which I consult more frequently. But Markham's bed layout system? Still using it. His composting calculations? Helpful. His optimistic production estimates? I smile and adjust downward.

The book taught me to think systematically about food production rather than just scattering seeds and hoping. That shift in mindset has value beyond any specific technique.

Would I recommend it to the version of myself from three years ago who was just getting serious about growing food? Yes, but with the caveat to also read at least two other books and not take every word as gospel.

The engineering approach isn't for everyone. Some people want their homesteading books with more soul, more storytelling, more connection to the land. That's valid. This book is tools, not poetry.

But if you're the kind of person who likes spreadsheets, appreciates optimization, and wants to maximize what you can grow in limited space, Mini Farming offers a framework worth studying—errors and all.

Just remember: two inches, not two feet.
