Commercial Garlic Farming Guide: Planning, Production, and Profitability

Key Takeaways

• Commercial garlic farming can net $5,000-$40,000 per acre — but only when the right market channel is matched to the right scale. Seed garlic buyers pay $10-$25/lb, which is 5-10x what wholesalers offer.
• Seed garlic is the biggest first-year cost — expect to spend $8,000-$62,500 per acre on garlic bulbs for planting alone, depending on variety and spacing. Saving 30%+ of your harvest as seed stock is how the economics improve over time.
• Start small and prove it first — one to two acres is the right starting point. Most first-year growers hit 60-70% of experienced yields while systems get dialed in.
• Variety selection determines profitability — hardneck varieties like Music and German White command premium seed garlic prices, while softneck varieties like Inchelium Red and Nootka Rose win on storage life and retail volume.
• Organic certification is worth pursuing — certified organic garlic sells for 2-3x conventional prices, and the premium more than covers the extra labor, especially for weed management.
• Weeds will be your biggest headache — plan for 50-100+ hours per acre of hand weeding on organic operations. Garlic’s root system simply can’t compete with weeds for nutrients on its own.
• Harvest timing is non-negotiable — too early means small bulbs, too late means split wrappers. Watch for 5-6 green leaves remaining and test dig before committing to full harvest.
• Never plant in the same ground two years in a row — minimum 3-4 year rotation, and some experienced farms go 8-10 years between plantings on the same ground to prevent disease buildup.

What This Guide Covers

There’s no sugarcoating it – commercial garlic farming isn’t easy money. But it can be really good money when done right. Zack Schallert and the Basaltic Farms team have been at this since 2018, learning more from mistakes than from any guide. That’s exactly why this resource exists – so other growers don’t have to make all the same mistakes.

Here’s what’s happening with garlic in America right now. Americans eat about 2.5 pounds per person every year, which is triple what the country consumed back in 1980. But here’s the thing – domestic garlic production only covers about 24,000 to 26,000 acres annually, mostly in California. The rest gets imported, mainly from China. That’s a problem for a lot of reasons, but it’s also an opportunity for growers who care about quality (Penn State Extension).

How much money can you make growing garlic? A well-run operation can see net margins of 30-70% depending on scale and sales channels. Small-scale garlic farming on 1-2 acres selling direct can gross $16,000-$60,000 per acre. That’s why commercial garlic farming attracts so many new growers each year.

This cornerstone guide covers the big picture of starting and running a garlic farming business. Each section links to detailed guides that go deeper on specific topics.

The Market Reality

U.S. Garlic Production Overview

California grows most of the garlic in this country – roughly 90% of domestic production. Oregon, Nevada, New York, and Washington grow some too, but it’s mostly California. Even with all that production, the United States is still the world’s biggest garlic importer. Most of it comes from China, then Spain, Mexico, and Argentina (Penn State Extension).

What does that mean for potential growers? It means there’s room. Especially for anyone growing something better than what people can get at the grocery store.

Where the Money Is in Commercial Garlic

Why People Want American Garlic

A few things are working in growers’ favor right now:

People want local. After everything that’s happened the last few years, consumers care more about where their food comes from.

Organic garlic demand keeps growing. Organic certification can bring 2-3 times what conventional garlic sells for.

Chefs want variety. Grocery store garlic is pretty boring. Chefs and home cooks who really care about food want to try different garlic varieties with different flavor profiles.

Import quality concerns. There’s been a lot of talk about bleaching and chemical treatments on imported garlic. Whether it’s all true or not, people are worried about it.

Is Garlic Farming Profitable?

The short answer: yes, commercial garlic farming can be very profitable. But the numbers depend heavily on scale, sales channels, and how well the operation is run.

Garlic Farming Income Potential

Why the huge range? It comes down to:

• Yield: 4,000-10,000 lbs per acre depending on spacing, variety, and management
• Price: $2-$25/lb depending on market channel
• Costs: $5,500-$33,000/acre depending on scale and seed costs

Garlic Farming Business Plan Basics

Before diving in, any serious garlic farming business plan should answer:

• What’s the target market? Direct, wholesale, seed, or mixed?
• What scale makes sense? Start small (under 2 acres) and grow
• What’s the capital situation? First year costs $12,000-$35,000/acre
• Who’s the labor? Family operation or hired help needed?
• What’s the 3-year plan? How fast to scale?

The Basaltic Farms team started on a few acres and scaled up each year as they figured things out. That’s the smart approach for garlic farming for beginners.

Money Talk – Economics by Scale

Here’s where the real numbers come in. The economics of commercial garlic farming change a lot depending on scale.

Small Scale Garlic Farming – Under 2 Acres

This is where most people start, and honestly where they should start. Sales happen at farmers markets, maybe some restaurants, CSAs, and online direct to customers.

Garlic farming costs per acre: $12,400-$33,200 (seed is the biggest chunk at $8,000-$24,000)

• Garlic yield per acre: 3,000-5,000 lbs estimated yield for newer growers
• Selling direct can bring $8-15/lb
• Gross revenue: $16,000-$60,000 per acre
• Garlic profit margins: 40-70% once things are dialed in

Medium Scale – 2-10 Acres

This is where operations start needing real garlic planting machines and maybe some help. Mix of direct sales, wholesale, and seed garlic sales.

Costs: $8,000-$18,000 per acre (efficiencies kick in)

• 4,500-6,000 lbs estimated yield per acre with experience
• Mixed channels average $6-12/lb
• Net margins: 35-55%

Large Scale – 10+ Acres

Wholesale and processing contracts become the main channels. This takes serious equipment investment including mechanical garlic harvesters.

Costs: $5,500-$12,000 per acre

• 6,000-10,000 lbs estimated yield per acre with optimization
• Wholesale garlic prices at $2-6/lb
• Net margins: 30-45%

Picking the Best Garlic Varieties for Profit

Variety selection makes or breaks a commercial garlic operation. It’s not just about flavor – it’s about what grows well in the local climate, what stores long enough to sell, and what buyers actually want.

Hardneck vs Softneck Garlic

Hardneck garlic varieties (Porcelain, Rocambole, Purple Stripe, etc) — the most sought-after seed garlic for serious growers:

• Need cold winters for proper bulbing
• Produce garlic scapes (bonus crop worth $8-15/lb)
• Stronger, more complex flavors
• Store 4-7 months
• Higher prices in specialty markets

Softneck garlic varieties (Artichoke, Silverskin):

• Tolerate warmer climates better
• No scapes
• Milder flavor, what most people know
• Store 8-12 months
• Better for wholesale/retail

Best Garlic to Grow for Profit

Start with 2-3 proven varieties for the region. Trial new ones on small plots before committing acreage.

Finding the Right Ground

What Garlic Needs From Soil

Soil type: Well-drained loam or sandy loam to clay loam, pH 6.0-7.0, good organic matter. Garlic hates wet feet – if water pools after rain, pick somewhere else.

Sun: Full sun, minimum 6-8 hours daily.

Air flow: Good circulation reduces disease pressure. Avoid low spots where cold air settles.

Climate Requirements and Vernalization

Hardneck garlic needs cold to form bulbs properly. This is called vernalization – roughly 40 days below 40 degrees F does the trick for most varieties. Without enough cold exposure, bulbs won’t segment properly. This is not a problem however for softneck varieties.

Garlic Crop Rotation

Never plant garlic (or any allium) in the same ground two years in a row. A minimum of 3-4 year rotation prevents disease buildup. Some farms go as long as 8 to 10 years before replanting in the same ground.

Good rotation partners:

• Brassicas (broccoli, cabbage)
• Legumes (beans, peas) – fix nitrogen
• Squash family
• Cover crops between garlic years
• Hay crops if going extended periods of time between garlic planting

Avoid following: Onions, leeks, shallots, or previous garlic or anything in the allium family.

Garlic Companion Planting

Garlic actually makes a great companion plant for other crops:

• Repels aphids, Japanese beetles, spider mites
• Works well near tomatoes, peppers, brassicas
• Avoid planting near beans, peas (stunts legume growth)

Field Layout & Plant Spacing

Layout decisions affect everything – garlic yield per acre, equipment options, labor efficiency, and bulb size.

The Basic Trade-off

Tighter garlic plant spacing = More plants per acre, smaller bulbs, better for processing

Wider garlic plant spacing = Fewer plants, bigger bulbs, better for fresh market and seed

Standard Commercial Garlic Spacing

The Basaltic Farms setup uses 2-3″ in-row spacing with wide row spacing to give plants plenty of room to develop. Even with the tighter in-row spacing, this approach consistently produces large bulbs – the generous space between rows is what makes the difference. It’s a good balance for seed garlic and fresh market sales.

*Plants/acre figures are calculated from row and plant spacing in a square field only. Actual plant count will be lower once tractor lanes, bed configuration, and variety separation are accounted for. Seed requirements work directly from these plant counts. At 60-70 cloves per pound – typical of large varieties including all of Basaltic Farms’ softneck varieties – expect to plant roughly 500-2,500 lbs of seed per acre for fresh market and seed production spacing, with Basaltic Farms typically planting 2,200-2,500 lbs per acre at their setup. Cloves per pound varies significantly by variety: jumbo varieties like Music run around 50 cloves per pound, large varieties like most softnecks fall in the 60-70 range, mid-size varieties like Chesnok Red reach around 100 cloves per pound. Most well-run operations can expect 4,000-8,000 lbs per acre on a normal to good year. A practical benchmark is what Basaltic Farms consistently achieves: 4,500-6,000 lbs per acre on a normal to good year.

Equipment Needs

Commercial garlic farming equipment needs scale with acreage. Starting small and growing into equipment as the operation proves itself makes more sense than buying everything upfront.

By Scale

Under 2 acres: Hand tools, basic tractor or walk-behind, undercutter, maybe a small transplanter. Total investment: $2,000-$15,000.

2-10 acres: Compact tractor (25-50 HP), bed shaper, mechanical garlic planting machine, cultivation tools. Total investment: $15,000-$75,000.

10+ acres: Full-size tractor, commercial garlic planter, digger, bulker, single and multi-row harvesters, harvester binders, processing equipment. Total investment: $75,000-$250,000+.

Key Equipment for Commercial Garlic

The Smart Approach

Rent or borrow specialized equipment the first few years. Buy what gets used constantly (tractor, basic implements). Custom hire what’s needed once a year (bed shaping, maybe harvesting).

For detailed equipment lists, see the Commercial Garlic Equipment Guide.

When to Plant Garlic by Zone

Garlic Planting Timing by USDA Zone

Fall planting is essential for commercial garlic farming. Garlic needs to establish roots before winter, then uses cold exposure to trigger bulb formation in late spring and early summer.

Plant 4-6 weeks before the ground freezes solid.

Seed Garlic Preparation

Break bulbs into individual cloves 1-2 days before planting. Keep the papery wrapper on. Sort by size – plant the biggest cloves, sell the smaller ones for eating.

Seed garlic cost per acre: 1,000-2,500 lbs depending on variety and spacing. At $8-25/lb, seed garlic is the biggest input cost year one. That’s $8,000-$62,500 just in seed.

Garlic Planting Depth by Climate

When planting by hand on a smaller scale, plant pointy end up, flat root end down for best yields. When using commercial planting equipment this becomes less important – the equipment can’t differentiate clove orientation, and at scale it’s simply not practical to worry about.

Mulching for Garlic

Mulch after planting for weed control, moisture retention, and winter protection. Use straw (3-4 inches) or leaves (4-6 inches). Mulching can be a practical and effective tool for small farms, but it becomes prohibitive at larger scales – generally more than 1-2 acres. Most larger operations skip mulch entirely and rely on cultivation and other weed management strategies instead.

Never use hay. It’s loaded with weed seeds. The Basaltic Farms team learned this the hard way – stick with actual straw.

Production Management

Watering Garlic

Garlic needs consistent moisture during active growth but hates wet conditions near harvest.

Garlic watering schedule:

• Fall establishment: 1″ per week if dry
• Winter: Nothing (dormant)
• Spring growth: 1-1.5″ per week
• Bulbing: 1″ per week
• Last 2 weeks before harvest: Stop completely

Drip irrigation works best for commercial garlic farming – efficient, reduces disease risk, easier to manage.

Fertilizing Garlic

Garlic is a heavy feeder, especially for nitrogen. Total season needs run about 125 lbs nitrogen, 150 lbs phosphorus, and 150 lbs potassium per acre (Penn State Extension).

Nitrogen schedule:

• Pre-plant: 30-40 lbs N/acre
• Early spring (6″ tall): 40-50 lbs N/acre
• Mid-spring: 30-40 lbs N/acre
• Pre-bulbing: Stop

Sulfur – The Overlooked Essential

Garlic is also an exceptionally heavy feeder on sulfur – more so than almost any other crop. This is not optional. The organosulfur compounds that give garlic its flavor, smell, and nutritional properties are only produced when sufficient sulfur is available. Sulfur-deficient garlic produces bland, weak-flavored bulbs that will not command premium prices regardless of how well everything else is managed.

Research shows garlic requires 2-3 times more sulfur per ton of crop than cereal crops, with most recommendations landing around 20-30 lbs of sulfur per acre per season (University of Georgia Extension). Apply a sulfur-containing fertilizer before planting and again mid-season. A soil test before planting is the best way to know where you stand.

Harvesting Garlic Scapes

Hardneck varieties send up a flower stalk (scape) in late spring. Removing garlic scapes increases bulb size by up to 30%. Plus scapes sell for $8-15/lb at farmers markets – that’s a nice bonus crop.

If you’re planning to sell the scapes, cut or snap them when they’ve made one curl but before they straighten. If you’re not selling them, wait until they fully straighten out but cut before the umbel (the flower pod at the top) begins to swell. Always cut 4 to 6 inches above the last leaf where the scape emerges from the plant – this avoids creating a pathway for disease to enter.

Weed Control

Weeds are the biggest headache in commercial garlic farming, especially for organic growers. Garlic can and does shade weeds out when planted densely, however it has very large coarse roots with few hair-like roots and does not compete well with weeds due to its inability to successfully compete with weed roots for available nutrients.

Organic Weed Control for Garlic

Prevention first:

• Clean seed (no weed seeds hitchhiking)
• Stale seedbed technique (prep beds early, kill first flush before planting)
• Heavy mulching (4-6 inches of straw)

Cultivation:

• Wheel hoes and stirrup hoes between rows
• Hand weeding in-row (unavoidable)
• Timing matters – small weeds are easy, big weeds are a nightmare

Reality check: Plan for 50-100+ hours per acre for hand weeding on organic operations. It’s the trade-off for organic garlic premiums.

Harvest & Curing

When to Harvest Garlic

Timing is critical for commercial garlic farming. Too early means small bulbs that won’t store. Too late means bulbs splitting open in the ground.

Garlic harvest timing signs:

• 5-6 green leaves remaining (each leaf = one wrapper layer)
• Bottom 3-4 leaves brown and dry
• Test dig a few bulbs – cloves should fill skins, wrappers intact

Most areas harvest late June through July. Hardneck garlic comes first, softneck follows.

How to Harvest Garlic

Small scale: Loosen with a digging fork, pull by hand, brush off soil.

Small to medium scale: Undercutter bar loosens the row, workers pull and windrow, field dry briefly then move to curing.

Large scale: Commercial harvesting equipment takes over – diggers windrow the garlic for a bulker to pick up, or single and multi-row harvesters and harvester binders handle the job.

Handle bulbs carefully – bruised garlic doesn’t store.

Garlic Curing Process

Proper garlic curing is what makes bulbs store for months instead of weeks.

Curing conditions:

• Warm (75-90 degrees F)
• Good airflow
• Out of direct sun
• Low humidity

Duration: 2-4 weeks until necks are completely dry and papery.

After curing, trim roots to 1/4″, cut stems to 1″ (hardneck) or leave for braiding (softneck), and grade by size.

Storage & Marketing

Garlic Storage Conditions

Never store in plastic bags – garlic needs to breathe. For seed storage, the goal is to emulate the conditions at harvest – cool, dry, and with good airflow around 55-65 degrees F. For prolonged cold storage intended to extend shelf life for eating or selling, keep garlic at 33-34 degrees F for maximum shelf life.

Marketing Channels for Commercial Garlic

Farmers market garlic sales: Highest prices ($8-15/lb), most work, limited volume. Great for small-scale garlic farming.

Restaurants/Chefs: Good prices ($6-10/lb), relationship-based, need consistent supply.

Retail/Grocery: Medium prices ($3-6/lb), larger volumes, may need food safety certification.

Wholesale garlic: Lower prices ($2-4/lb), big volumes, least work per pound.

Seed garlic sales: Premium prices ($15-25/lb), specialized market, reputation matters.

Most successful commercial garlic operations use multiple channels – direct sales for the best bulbs, wholesale for volume, seed sales for premium stock.

Scaling Your Garlic Farming Business

When to Expand

Don’t scale until:

• Current acreage is profitable and manageable
• Systems are documented and repeatable
• Markets exist for increased production
• Capital (or financing) is in place

How to Scale Commercial Garlic Farming

Year-over-year growth: 25-50% expansion is manageable. Doubling every year leads to chaos.

Seed forward: Save 30%+ of harvest as seed stock to reduce costs as scale increases. This is how garlic farming becomes more profitable over time.

Equipment timing: Buy equipment when it pays for itself in saved labor, not before.

Hire help: Harvest and weeding are the bottlenecks. Seasonal labor makes more sense than year-round employees for most operations.

For detailed scaling strategies, see the Growing Your Garlic Operation guide.
