The Sweet Potato Market in 2026

Sweet potatoes have quietly become one of the better-paying row crops in North America. The US market reached about $771 million in 2024, up 6% on the year, while the value of US production sat near $867 million (IndexBox, 2024). Globally the crop is worth roughly $18.1 billion in 2025 and is forecast to grow at a 4.74% CAGR to $28.77 billion by 2035 (Market Research Future, 2025). The pull is health-driven: shoppers in North America keep trading white potatoes for the higher-fibre, beta-carotene-rich alternative.

Supply is concentrated. North Carolina alone grows roughly 60% of all US sweet potatoes and the crop is a $350 million slice of that state's farm economy (NC SweetPotato Commission). Mississippi, Louisiana and California make up most of the rest. US harvested acreage actually rose by 23,300 acres in 2024 to about 148,200 acres, even as a drought-then-rain season pushed North Carolina's average yield down to 150 cwt per acre from 195 cwt the year before (The Packer, 2024). That swing matters for your plan: more acres plus a soft yield means a buyer-friendly market, so your financial model should stress-test a lower grower price rather than assume the good years.

The UK and most of Europe import the bulk of what they eat, largely from the US, Spain, Egypt and Israel, which is exactly why a domestic UK grower with the right storage can win a premium against air-freighted stock. The crop grows in the UK under fleece or polytunnel in the warmer south, and demand has tracked the same health-food trend as the US.

Questions Growers Ask First

These are the questions that show up in search and in our first calls with would-be sweet potato growers. Settle them before you write a line of the plan, because each one changes a number in the model.

How long does it take from slips to harvest?

Most commercial varieties are lifted 90 to 130 days after the slips go in, with 90 to 120 days typical for Covington and Beauregard (Wikifarmer). That single growing window means one main cash event a year, so your cash-flow forecast has to carry operating costs from spring planting all the way to autumn sale.

How long must the crop cure and store?

Curing runs 4 to 10 days at 80-85°F (27-29°C) and 85-90% humidity; if you cannot reach those conditions, extend to 14-21 days at a cooler 65-75°F. Cured roots heal harvest wounds, sweeten as starch converts to sugar, and then hold for months near 55-60°F. Storage is the difference between selling everything at the harvest-week low and packing graded boxes to order across the whole year.

What yield can a new grower realistically plan for?

Plan conservatively. A common working figure is 300-350 bushels (50 lb each) per acre, with 800-1,000 bushels possible under irrigation in the deep South. New growers without seasoned harvest crews and tight curing should model the low end and treat the upside as a bonus, not a base case.

What It Costs to Get in the Ground

Published estimates for a small-to-mid commercial sweet potato farm run from about $63,900 to $224,800 in the US, or roughly £40,000 to £160,000 in the UK on a comparable scale (BusinessPlan-Templates, 2025). The spread is enormous because two line items dominate everything else: harvesting and curing machinery, and the building you cure and store in. Get those two right and the rest is rounding.

Cost Breakdown

• Land (buy or lease): $1,500-$6,000/acre to buy, or $50-$250/acre/yr to lease (UK £60-£250/acre/yr)
• Certified disease-free slips (~15,000/acre): $400-$600/acre (£300-£500/acre)
• Drip or overhead irrigation: $1,000-$5,000/acre; budget $15K-$30K for a 5-10 acre block
• Tractor, transplanter & mechanical digger/harvester: $30,000-$200,000 (£25K-£160K)
• Curing + climate-controlled storage shed: $10,000-$40,000 (£8K-£32K)
• First-season operating inputs (fertiliser, labour, pest control): $2,500-$4,000/acre

A 10-acre first season therefore needs roughly $25,000 to $40,000 in operating budget on top of the capital outlay, before you have sold a single box. Labour is the line new growers underestimate most: even with a mechanical harvester, sweet potatoes need around 60 man-hours per acre (Oklahoma State Extension), because hand-grading and field handling protect the delicate skins that decide your grade and price.

Phasing the capital, not front-loading it

The smart way to keep the startup figure near the bottom of that range is to phase the capital against acreage. A first-year grower on 10 to 20 acres can lease land, buy a second-hand digger and bed shaper, and build a modest curing barn, deferring the wash-and-pack line until storage volumes justify it. Input costs have been the real pain point in recent seasons: fertiliser, fuel and labour all rose, so growers planning a 2026 launch should price inputs at current rates rather than last year's (The Packer, 2024). The financial model in this template separates one-off capital from recurring per-acre inputs so a lender can see exactly which costs scale with your acreage and which do not.

Equipment & Supplier Checklist

Sweet potatoes are not a crop you can launch with a rotavator and good intentions; the machinery is what makes acreage profitable. Here is the core kit, with the price bands lenders expect to see itemised.

• Utility tractor (45-90 hp): $20,000-$60,000 used to new, the backbone for tillage, bedding and planting
• Bed shaper / plastic-mulch layer: $4,000-$12,000, sweet potatoes are grown on raised beds for drainage
• Mechanical transplanter (slip setter): $3,000-$15,000, sets 15,000+ slips/acre far faster than hand
• Vine cutter / flail mower: $2,500-$8,000, vines are cut before lifting
• Chain or shaker digger / harvester: $8,000-$60,000+, the single biggest mechanisation decision
• Field crates / bulk bins: $1,500-$10,000, for moving roots without bruising
• Curing & storage building with humidity and temperature control: $10,000-$40,000
• Grading / washing / packing line: $5,000-$50,000 depending on whether you pack on-farm

Where growers source inputs

For certified slips, the major US names are the North Carolina nursery growers and specialists such as Steele Plant Company (Tennessee) and George's Plant Farm for smaller orders, plus regional nurseries tied to the North Carolina SweetPotato Commission for commercial volumes. Used harvesting and bedding equipment moves through dealer networks and auction sites; many first-year growers buy a second-hand digger to keep the capital line down. Whoever you choose, your plan should name the slip variety (usually Covington, sometimes Beauregard or Orleans) because the variety drives yield, storage life and which packer or retail buyer will take the crop.

How the Money Actually Works

Most guides on sweet potato farming stop at "you can make money." The number that actually decides whether you do is the gap between your field net of roughly $1,000 per acre and the far larger margin available to growers who store, grade and sell branded (Business North Carolina). Fresh-grade grower prices commonly sit around $18-$30 per cwt (a cwt is roughly 45 kg), and they soften fast in a high-acreage year. The same root sold washed, graded and packed under a label can clear several times that.

A worked 25-acre example

Take a 25-acre North-Carolina-style block at 250 cwt per acre (a realistic, conservative yield) and a blended grower price of $24 per cwt. That is 6,250 cwt × $24 = about $150,000 of gross revenue. Subtract first-season inputs at roughly $3,200/acre ($80,000), then curing, grading and freight, and the land net lands near $1,000/acre, or about $25,000 before overhead and your own time. Push the same crop through storage so half of it sells in spring at a $6-$10/cwt premium, or move into direct, restaurant or branded retail channels, and that net can double. This is precisely why the serious operators chase scale, storage and a packing relationship rather than dumping at harvest.

Revenue streams to model

• Fresh wholesale to packers/shippers: baseline volume, lowest price, fastest cash
• Stored and graded sales: sell across the year at a premium thanks to curing + storage
• Direct-to-consumer & farmers' markets: highest per-unit price, limited volume
• Value-added (cubed, dried, sweet-potato fries, pet treats): captures processing margin
• Cull and #2 grade to processors or livestock: turns waste into recovery, not landfill

Why a UK grower can charge more

The UK and most of Europe import the overwhelming majority of the sweet potatoes they eat, mainly from the US, Spain, Egypt and Israel. That import dependence is the opportunity: produce harvested days rather than weeks before sale, with a Red Tractor badge and a "British-grown" line on the label, can command a premium a container of air-freighted roots cannot. A UK plan should make import substitution its central argument and size the addressable demand from the retailers and box schemes already paying up for local provenance, rather than trying to beat imports on raw cost per kilo.

Where to Grow: Regional Demand & Price

Sweet potato economics shift sharply by region, and a plan a lender trusts says where and why, not just "we will grow sweet potatoes." The crop wants well-drained, sandy loam soil with a pH of roughly 5.8 to 6.5 and a long, warm season, which is why the US industry clusters in a handful of states.

• North Carolina: the powerhouse at ~60% of US output and a $350M state industry, with deep packer and export infrastructure built around the Covington variety. Best place to plug into an existing buyer network, but also the most competitive on price.
• Mississippi & Louisiana: strong heritage growing regions; Mississippi averaged about 120 cwt/acre in 2024. Vardaman, Mississippi markets itself as the "Sweet Potato Capital." Good agronomy, less crowded export logistics than NC.
• California & the deep South: irrigation plus a long season can push yields toward the 800-1,000 bushel/acre upper band, supporting premium and organic positioning for West Coast retail.
• UK (southern England): a small but growing domestic crop under fleece or polytunnel, competing on freshness against imports from the US, Spain, Egypt and Israel. The play is local, certified and short-shelf-life-beating, not volume.

Demand is broad-based and counter-seasonal to your harvest: Thanksgiving and the winter holidays drive a US consumption spike, which is the single best argument for investing in storage so you can hold graded stock into that window rather than selling at the autumn-harvest low. Your plan should map the target region's soil, frost dates, water rights or abstraction licence, and the nearest packer or wholesale market, then tie each to a line in the cost model.

Operations: Field to Pack-House

The operations section is where most first-time plans go thin and where a grower-experienced reader (an FSA loan officer, an agronomist, an investor's adviser) decides whether you actually know the crop. Walk the reader through the full cycle with real numbers attached.

Land preparation and planting

Sweet potatoes are grown on raised beds for drainage, formed with a bed shaper after deep tillage. Most commercial growers transplant certified slips at around 15,000 plants per acre using a mechanical transplanter, timed so the soil is reliably warm. A soil test before planting sets your fertiliser plan and flags pH correction; the plan should name the lab and the target nutrient levels rather than wave at "soil preparation."

The growing season

Across the 90 to 130 day season the main jobs are irrigation scheduling, weed control while the canopy closes, and scouting for the pests that hit grade hardest, including the sweet potato weevil, wireworm and foot rot. Because the crop is in the ground for a single long window, irrigation reliability is not a luxury; a dry spell at bulking can cut both yield and the smooth skin that determines premium grade.

Harvest, curing and storage

Vines are cut first, then the roots are lifted with a chain or shaker digger and moved in field crates or bulk bins to limit bruising. The crop is cured for 4 to 10 days at 80-85°F and 85-90% humidity to heal wounds and convert starch to sugar, then held in climate-controlled storage near 55-60°F. This is the step that turns a one-week harvest into a twelve-month sales business, and it is the line item lenders most want to see fully costed.

Grading, packing and dispatch

Out of storage, roots are washed, graded by size and quality (US No. 1, jumbos, #2s and culls), and packed to the buyer's spec. The grade mix drives revenue more than total tonnage: a high share of clean US No. 1s in the premium window is worth far more than a heavier crop sold mixed at harvest. The operations plan should state your target grade split and how curing, careful handling and storage protect it.

FSA, SBA & Grower Funding

Sweet potato farms are usually financed differently from a high-street business, because the USDA Farm Service Agency (FSA) exists precisely to lend to growers, often where a commercial bank will not. The two routes most new growers use are the FSA Farm Operating Loan and the FSA Microloan, with microloans up to $50,000 carrying lighter paperwork and beginning-farmer set-asides. Operating loans can run much larger and cover land, equipment and inputs. These programmes still expect a real plan with a five-year forecast, a break-even and a repayment schedule, exactly what this template is built to produce.

The SBA 7(a) programme is a better fit for the off-field side of the business: a packing line, a value-added processing unit, or a cold-store you also rent to neighbours. SBA loans go up to $5 million with terms up to 25 years, and lenders will want SBA-formatted financials. In the UK, the government-backed Start Up Loan offers up to £25,000 at a fixed 6% with free mentoring, and DEFRA's farming grant schemes (such as the Farming Equipment and Technology Fund) periodically co-fund irrigation, storage and handling kit. Whichever door you knock on, the make-or-break document is the same: a financial model the lender can trust. Our $300/£250 and $1,000/£800 packages build that model to lender standard.

Food Safety & Legal Requirements

There is no single "sweet potato licence," but produce sold into wholesale or retail is governed by food-safety rules that buyers enforce harder than regulators do. Build compliance into the plan from day one.

United States

• FSMA Produce Safety Rule (FDA): covers farms with produce sales over $25,000/yr; at least one supervisor must complete the PSA Grower Course (around $25-$75)
• USDA GAP / GHP audit (USDA AMS): voluntary but demanded by most packers and supermarkets; auditor time runs about $92/hr plus travel
• Very small business exemption: under $25,000 in annual produce sales you are exempt from federal FSMA inspection, but state and local rules still apply
• State department of agriculture registration and any local water-use or pesticide-applicator permits
• Note: sweet potatoes are on the FDA's "rarely consumed raw" list, which changes how parts of the rule apply

United Kingdom

• County Parish Holding (CPH) number from the Rural Payments Agency, free, issued in about 10 working days via 03000 200 301
• Single Business Identifier (SBI) and customer reference number, issued alongside the CPH
• Red Tractor Fresh Produce certification, the de facto requirement to supply UK supermarkets
• Registration with the local authority as a food business and adherence to general food hygiene law

Canada & Australia

In Canada, retail and wholesale buyers generally require CanadaGAP food-safety certification on top of provincial farm registration, with financing available through AgriInvest and the Canadian Agricultural Loans Act. In Australia, the major chains require Freshcare or HARPS certification, and growers need an ABN plus state biosecurity registration. The template's compliance section adapts to whichever jurisdiction your plan targets.

Selling the Crop: Channels & Marketing

A sweet potato farm lives or dies on where the crop is sold, not on whether it grows. The grower price you assume in the model should follow directly from the channel mix you can actually secure, so write the marketing plan before you finalise the financials.

The channel ladder, lowest to highest price

• Packer / shipper wholesale: you sell bulk to an operation like Scott Farms or Wada Farms that grades, packs and brands. Lowest price, least marketing effort, fastest cash, a sensible baseline for a new grower.
• Direct wholesale to retail or foodservice: requires GAP certification and reliable volume, pays better than packer sales, and rewards a consistent grade.
• Branded and stored retail: your own pack and label, sold across the year out of storage. This is where storage investment converts into margin.
• Direct-to-consumer: farmers' markets, farm shop, CSA boxes and online. Highest per-pound price, capped by how much you can move locally.
• Value-added: cubed, dried, fries, flour or even pet treats. Captures processing margin and uses #2 grade that would otherwise sell as culls.

Positioning that actually moves stock

The strongest stories for a smaller grower are local and traceable (especially in the UK, against imported stock), organic or low-spray where the soil and rotation support it, and variety-led (a named Covington or a specialty purple or Japanese type for chefs). Certification badges are marketing assets as much as compliance documents: a Red Tractor or GAP logo is what gets you past a supermarket buyer's first filter. The plan should name the two or three buyers you will approach first and what each one requires, so the reader sees a route to revenue rather than a hope.

Mistakes That Sink First-Year Growers

Sweet potatoes punish a few specific errors harder than most crops. Address each of these in the plan and you are already ahead of the typical first-year grower.

• Planting before storage is sorted. If curing and climate-controlled storage are not ready at harvest, the crop spoils or sells wet at low grade. Storage is not optional infrastructure for this crop; it is the business model.
• Using uncertified or self-saved slips. Carrying in foot rot, scurf or weevil destroys yield and grade. Certified disease-free slips at $400-$600/acre are cheap insurance.
• Underwriting on a peak price. A 2024-style yield drop to 150 cwt/acre or a fresh-grade price near $18/cwt can wipe out the margin. Stress-test the low case in your model.
• Treating the FSMA rule as paperwork for later. The first wholesale buyer will ask for proof of the PSA Grower Course and a GAP audit. Build it into year-one operations, not year three.
• Pricing labour as an afterthought. At ~60 man-hours/acre, harvest crew availability and cost decide your season. Line up labour before you scale acreage.

Sweet Potato Grower Glossary

The terms a lender or buyer will expect you to use correctly in the plan:

• Slip: the rooted sprout grown from a mother root and transplanted to the field; the crop is propagated from slips, not true seed.
• Cwt (hundredweight): the standard trade unit, 100 lb (about 45 kg); grower prices are quoted per cwt.
• Bushel: a sweet potato bushel is reckoned at 50 lb; yields are often quoted in bushels per acre.
• Curing: the controlled warm, humid period after harvest that heals wounds, sweetens the root and extends storage life.
• US No. 1: the premium fresh grade; size and skin quality decide how much of your crop earns it.
• Covington: the dominant US commercial variety, prized for uniform shape, colour and storage.
• FSMA Produce Safety Rule: the FDA food-safety standard most commercial growers fall under.
• GAP / CanadaGAP / Freshcare: the buyer-required food-safety audits in the US, Canada and Australia.
