Citrus (except Orange) Groves — U.S. Industry Primer

NAICS 2022 code 111320 (NAICS = North American Industry Classification System)

---

1. Overview

This industry is the farming of every commercial citrus fruit except the orange: lemons, limes, grapefruit, and the fast-growing easy-peel mandarins and tangerines (the fruit behind brands like Halos and Cuties). These are permanent tree crops — a grower plants an orchard, waits three to five years for it to bear, then harvests it for decades. The economics are those of a branded fresh-produce grower, not a bulk commodity farmer: most of this fruit is sold fresh at the supermarket, so eating quality, variety, brand, timing, and marketing scale drive returns more than sheer tonnage does.

The industry is in the middle of a dramatic geographic reshuffle. California now grows the large majority of U.S. citrus — on the order of four-fifths — while Florida's once-dominant crop has collapsed under a bacterial tree disease.[1][7] Fresh mandarins are a genuine growth story; grapefruit is in secular decline; and limes are almost entirely imported. Returns hinge on productive trees, reliable water, disease control, harvest labor, and access to packers, marketers, and retailers.

For anyone allocating capital, the defining feature is that there is very little to buy on public markets: the biggest players are private (The Wonderful Company) or grower-owned cooperatives (Sunkist), and the one near-pure listed name (Limoneira) is a lemon-and-real-estate business. The public route is thin; the private route — direct groves, farmland funds, water rights — is where most of the capital actually sits. The best assets are not necessarily the largest groves; they are groves with durable water access, healthy trees, high fresh-market packout, strong customer relationships, and land-use optionality.

2. What it is and how it's structured

Scope. NAICS 111320 covers establishments primarily engaged in growing citrus other than oranges — grapefruit, lemon, lime, tangerine, mandarin, tangelo, citron, and kumquat groves.[4] It is a production-agriculture code: the farming/growing activity itself, not the packing, juicing, or selling of the fruit. A grove business typically spans nursery stock and tree establishment, irrigation, fertilization, pruning, pest and disease management, harvesting, and delivery to the farm gate. Packing, shipping, processing, and retail branding may be done by the grower or outsourced.

What it excludes (and the adjacent codes).

• Orange Groves — NAICS 111310. Oranges are a separate industry, even though the same companies often grow both.[1][4]
• Packing, washing, waxing, and cold storage after harvest falls under postharvest crop support (NAICS 115114); juicing/canning is food manufacturing (e.g., NAICS 311421, fruit-and-vegetable canning); fresh wholesale distribution is NAICS 424480.
• Other fruit and tree-nut farming sits in its own codes (NAICS 111331–111339). Farm-management and farm-labor services fall under support-activity codes, not grove production.[4]

Ownership mix. The industry has a barbell shape. At one end sit a handful of very large, vertically integrated private growers that also pack, ship, and market their own fruit — most notably The Wonderful Company (America's largest citrus grower) and Sun Pacific, plus family-owned diversified operators such as Florida's DUDA.[8][24][25] Alongside them is Sunkist Growers, a member-owned marketing cooperative founded in 1893 through which more than a thousand family growers across California and Arizona pool and sell their fruit — a grower network, not a single corporate owner.[10] At the other end is a long tail of small independent family farms (most Florida groves, for instance, are family-owned and operated). Very few operators are publicly traded, and the exact ownership split for this code is not available in federal statistics.

3. How big it is

Our federal ground-truth figure. The one number in our ingested federal file for this code is the U.S. Small Business Administration (SBA) size standard of $4.25 million in annual receipts — the ceiling below which a citrus-except-orange farm counts as a "small business" for federal-program eligibility.[5] It is a program threshold, not an estimate of industry revenue. Essentially every operation clears it as "small," even though a few private giants are many times larger. Our file carries no federal firm count, employment, payroll, or receipts total for this code, so we do not state one; those figures should not be inferred.

A caveat on business counts — this industry is structurally undercounted. Standard "how many companies" datasets miss it by design. The Census Bureau's Statistics of U.S. Businesses (SUSB) and its Nonemployer Statistics both exclude Crop Production (NAICS 111); farms are instead enumerated separately by USDA's (U.S. Department of Agriculture) Census of Agriculture.[16] Commercial business-database aggregators list on the order of ~600 citrus-except-orange establishments with employees,[17] but that captures neither the long tail of tiny sole-proprietor groves nor the reality that a large share of national acreage and volume sits inside a few big private and cooperative entities. The meaningful size gauge here is physical production, not business registrations.

Production and value (2024–25 season; USDA NASS). USDA's National Agricultural Statistics Service (NASS) reports U.S. utilized production for the three non-orange types this code covers at roughly:[1][2]

• Tangerines and mandarins — about 1.23 million tons (the largest of the three; category includes tangelos and tangors)
• Lemons — about 1.12 million tons
• Grapefruit — about 300,000 tons

That is on the order of 2.6–2.7 million tons combined — now more than all U.S. orange tonnage (2.39 million tons and shrinking), a reversal of the industry's historic shape.[1] Total U.S. citrus crop value across all types (including oranges) was about $2.84 billion in 2024–25, down 4% year over year.[1] These NASS categories exclude limes (the U.S. barely grows them — see below). USDA's April 2026 forecast put the 2025–26 crop modestly lower still, with grapefruit, tangerines/mandarins, and lemons all below their prior-year levels (roughly 2.65 million tons combined).[2]

Where it's grown. California dominates. Its 2024 bearing acreage was about 64,900 acres of mandarins/mandarin hybrids, 49,800 acres of lemons, and 8,200 acres of grapefruit (on top of its large, separately-coded orange acreage).[6] Arizona adds a small lemon crop (~3,100 bearing acres, ~38,000 tons); Texas grows mostly grapefruit (~13,400 bearing acres).[3] Florida — historically the grapefruit heartland — has been gutted: statewide citrus land fell from about 748,555 acres in 2004 to roughly 274,705 in 2024.[7]

Limes are the missing domestic crop. The U.S. essentially no longer grows limes at commercial scale — more than 99% of limes consumed are imported, over 80% of them from Mexico, with U.S. fresh-lime imports reaching about 1.70 billion pounds in 2024 (up 9%).[9] So while "lime groves" sit inside this code on paper, the lime you buy is an import story, not a U.S.-farming one.

4. The investable universe

The public-market menu is genuinely thin. Only one company is anything close to a pure play, and even it is a lemon-and-real-estate business. The bulk of the industry — Wonderful and Sunkist — is not investable at all.

Major private and cooperative owners (not investable):

• The Wonderful Company / Wonderful Citrus (private; owned by Lynda and Stewart Resnick) — America's largest citrus grower, an integrated grow-pack-ship-brand platform farming roughly 74,000 acres of citrus (orange and non-orange combined); its Wonderful Halos mandarins and Wonderful Seedless Lemons are category leaders.[8]
• Sun Pacific (private) — a large California grower-packer-shipper, the original partner behind the "Cuties" mandarin brand, and active in lemons and other citrus.[25]
• DUDA / Duda Ranches (private) — a family-owned, Florida-based agriculture and real-estate business with more than 45,000 owned or leased acres overall; its citrus includes tangerines and grapefruit (no separate citrus-acreage figure disclosed).[24]
• Sunkist Growers (member-owned cooperative) — a marketing platform for more than a thousand family growers across California and Arizona, not a single grove owner; its value is collective packing, marketing, brand, and distribution (Limoneira rejoined as a member in 2025).[10]

Farmland investment companies can offer agricultural-land exposure, but investors should not assume they own citrus groves unless crop-specific holdings are disclosed. Bottom line: an investor wanting direct, meaningful exposure to growing this fruit has essentially one small public name (Limoneira) and otherwise must go private.

5. How the money works

Think of a grove as a long-lived capital asset that pays out fruit for decades. At the grove level, revenue is broadly marketable boxes × realized price — or equivalently bearing acres × yield per acre × price per unit, minus growing, harvest, and marketing cost. Each term behaves in ways specific to fresh citrus:

• Fresh-market premium. Lemons and easy-peel mandarins are sold overwhelmingly fresh, which pays far more per ton than juice/processing. That is the core reason this "except-orange" basket has held its value while juice oranges collapsed. Grade, size, appearance, shelf life, and timing — not just tonnage — determine the check; processing is mainly an outlet for lower-grade fruit at lower realization.
• Brand and "club" varieties. Proprietary, trademarked varieties (Halos, Cuties, branded seedless lemons) and licensed cultivars command premiums and repeat demand. Scale and marketing muscle win: a large integrated grower-packer-shipper or a cooperative can build a brand and supply a retailer year-round; a small independent generally cannot, and often markets through a cooperative instead.[8]
• The cost stack is labor- and water-heavy. Citrus is hand-harvested, and labor is the single biggest expense on fruit farms — on the order of 38 cents of every dollar of farm expense.[15] Water is the other structural cost, since the prime growing regions (California's Central Valley, Arizona, south Texas) are arid and depend on irrigation. Pest/disease control (especially against citrus greening), hauling, and packing/marketing round it out. Cash flow is seasonal: growers pay for irrigation, labor, and inputs before the crop proceeds arrive, and trees tie up capital for years — so leverage and liquidity matter.
• Slow supply, sharp cycles. Because a new orchard takes years to bear, growers cannot ramp supply quickly when prices are high or cut it fast when they're low. Prices swing with weather shocks (freezes, hurricanes), the trees' natural alternate-bearing rhythm, and import competition — returns are cyclical and biology-driven.
• Land and water as hidden value. In California and Florida the dirt and the water rights under a grove can be worth as much as the fruit. Limoneira explicitly runs a real-estate and water-rights business alongside its lemons, and Alico's whole 2025 pivot was to monetize land value once citrus stopped paying.[11][12] For private investors this optionality is often the real thesis.

For a public company, separate the economics of (1) grove production, (2) third-party fruit procurement, (3) packing and marketing, (4) real estate, and (5) other crops. A company can report strong citrus revenue while earning most of its margin from packing, land appreciation, or unrelated crops.

6. What drives demand

The long-term trend favors lemons, limes, mandarins, and other convenient citrus over traditional grapefruit and breakfast oranges. USDA's loss-adjusted fresh-citrus availability was about 8.4 pounds per person in 2022; from 1970 to 2022, lemon availability roughly doubled and lime availability rose about 24-fold.[18]

• The easy-peel mandarin boom. Seedless, kid-friendly, snackable mandarins turned a niche fruit into a supermarket staple over the past decade and remain the segment's growth engine.[8]
• Lemons: steady and defensive. Culinary, beverage, bakery, food-service, and health/wellness use keep lemon demand stable.
• Limes: strong but import-fed. U.S. lime consumption keeps rising, driven by cocktails and Mexican cuisine — but that demand is met by Mexico, not U.S. groves.[9]
• Grapefruit: shrinking. Consumption has fallen for years (an aging consumer base and well-publicized interactions with common medications), compounded by the supply collapse.[7]
• Imports as a structural feature. Year-round retail availability increasingly runs through imports. USDA forecast U.S. tangerine and mandarin imports of 555,000 metric tons for 2025–26 — nearly half of fresh consumption.[19] Demand growth may therefore benefit importers, packers, and brands as much as domestic grove owners.
• Health, beverages, and exports. Vitamin-C positioning, juice/flavor uses, and export markets (Sunkist ships California/Arizona fruit to Asia) all support demand.[10] Population, income, and foodservice provide the slow-moving baseline.

---

7. Regulation

• Plant-health quarantines are the defining regulation. USDA's Animal and Plant Health Inspection Service (APHIS) and state agriculture departments run quarantine zones and movement restrictions (under 7 CFR 301.76) to fight Huanglongbing (HLB, "citrus greening") — a bacterial disease with no established cure, spread by the Asian citrus psyllid — which can render infected fruit unmarketable as fresh produce. These rules govern where trees and fruit can move across every growing state.[20]
• Food safety. The Food and Drug Administration's (FDA) Produce Safety Rule, under the Food Safety Modernization Act (FSMA), sets standards for growing, harvesting, packing, and holding produce — worker hygiene, agricultural water, soil amendments, equipment, and buildings.[21]
• Pesticides. The Environmental Protection Agency (EPA) regulates pesticide use under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and its Agricultural Worker Protection Standard (WPS) governs training, exposure, records, and re-entry; California's Department of Pesticide Regulation adds a stricter state layer.[22]
• Labor. The Department of Labor (DOL) administers farm-wage, housing, transportation, and contractor rules and the H-2A temporary agricultural guest-worker program, which sets a mandated wage — the Adverse Effect Wage Rate (AEWR), roughly $20/hour in California — plus employer-paid housing and transport. H-2A now supplies about 15% of U.S. crop-farm employment and harvests much of the citrus crop, so immigration and farm-labor policy are first-order cost drivers.[15]
• Water. In California, groundwater use is being tightened under the Sustainable Groundwater Management Act (SGMA), a structural constraint on Central Valley permanent crops; surface-water allocations and drought rules add exposure. Florida growers face state and regional water-use permitting.[26]
• Risk management. Federal crop insurance (USDA Risk Management Agency, RMA) covers specialty crops including lemons, grapefruit, mandarins, tangerines, and tangelos in eligible areas — reducing, but not eliminating, biological and weather risk.[23]
• Grower-funded research. Bodies such as California's Citrus Research Board levy assessments to fund HLB and production research.

Regulation raises costs, but compliance capability can itself be a competitive advantage for larger growers and packers.

8. Competitive dynamics and consolidation

The industry is fragmented at the grove level but concentrated in commercial channels, and the center of gravity has shifted hard toward California and toward a few large, integrated players. Growing, packing, shipping, and branding under one roof — plus proprietary varieties — creates real barriers: Wonderful and Sun Pacific, together with the Sunkist cooperative, account for a dominant share of the fresh California mandarin and lemon supply.[8][10]

Crucially, a packer or brand can control market access without owning equivalent acreage. Limoneira's 2025 filing shows the split plainly: it packed and sold 4.7 million cartons of lemons, but ~78% of that fruit came from third-party growers.[11] Consolidation therefore runs through packing/cold-storage capacity, marketing cooperatives, branded retail programs, water-right acquisitions, and import/distribution networks — not just grove roll-ups. Small independents increasingly either market through a cooperative or exit.

The other half of the story is regional attrition. Florida grapefruit is in secular collapse from HLB and hurricanes; Texas grapefruit is small and exposed to freezes (a February 2021 freeze wiped out roughly 60% of the crop) and now HLB as well; Arizona is a modest lemon niche.[7] As Florida and Texas shrink, California's share climbs — consolidation across geography as well as companies. Alico's 2025 decision to abandon citrus entirely and become a land company is the clearest signal of where the Florida side is headed, and a reminder that land value can eclipse agricultural cash flow for some owners.[12] A smooth roll-up is still hard: disease, water constraints, long biological cycles, family ownership, and local land-use politics make assets heterogeneous.

9. Risks

• Citrus greening (HLB) — the existential risk. No cure. The disease destroyed most of Florida's citrus and is present, via the psyllid, in California and Texas; a breakout in California's commercial groves would threaten the whole domestic industry.[7][20]
• Weather and climate. Freezes (Texas 2021), hurricanes (Florida), heat, drought, and wildfire can erase a season's crop and damage long-lived trees, with no quick recovery given multi-year tree cycles.[7]
• Water cost and availability. SGMA and drought raise the cost and cap the availability of the irrigation that arid-region citrus cannot live without.[26]
• Labor cost and availability. Rising H-2A wages, housing mandates, and immigration-policy swings hit a crop that must be hand-picked and is hard to fully mechanize.[15]
• Price cyclicality and imports. Commodity-like price swings, plus import competition (limes from Mexico; off-season lemons from Argentina, Chile, and Mexico; roughly half of fresh mandarin consumption now imported), can cap domestic pricing and squeeze margins.[9][19]
• Long capital lead time. Years to bearing means growers can't dodge downturns or chase upturns quickly.
• Consumer shifts. The structural decline in grapefruit demand shows how a category can fade.[7]
• Customer/packer concentration and private-company opacity. A grower may have little pricing power against a dominant packer or retailer, and for private targets, acreage, debt, water rights, related-party dealings, and true cash margins can be hard to verify.

10. How to invest and the outlook

Public-market routes (limited).

• Limoneira (LMNR) is the only near-pure public play — analyze it as lemons-plus-real-estate-and-water, not a pure grove or a mandarin producer. Track lemon acreage, yield, packout, third-party procurement, packing margins, water, debt, land sales, and its non-citrus segments.[11]
• Alico (ALCO) is now a Florida land story after its 2025 citrus exit — of interest for land-value monetization, not fruit.[12]
• Fresh Del Monte (FDP) and Dole (DOLE) offer only diluted, indirect exposure inside large diversified produce businesses.[13][14]
• There is no citrus ETF (exchange-traded fund). Broad farmland vehicles (e.g., farmland-owning REITs — real estate investment trusts) may hold some permanent-crop citrus acreage among many crops, giving thin, indirect exposure. The two largest owners — Wonderful (private) and Sunkist (a cooperative) — cannot be bought at all.

Private-market routes (where most capital actually goes).

• Direct grove ownership or long-term leases — buying/leasing bearing lemon/mandarin acreage and operating it or leasing to a grower-packer.
• Farmland funds and platforms that syndicate permanent-crop citrus/lemon orchards to accredited investors, often bundling the crop return with land appreciation and water rights.
• Joint ventures, private credit, or orchard-renovation capital secured by land, trees, or packing assets.
• Water rights as a stand-alone California asset; and ag-tech and inputs (HLB-tolerant rootstock, disease treatment, harvest mechanization) as picks-and-shovels bets on the industry's survival problem.
• Before investing, verify title, water rights, permits, tree age and variety, disease history, historical yields, packout, fresh/processing mix, labor arrangements, insurance, customer concentration, debt terms, and land value without development assumptions.

Outlook (forward-looking judgment). The healthy part of this industry is clear: California-based, fresh-market, branded mandarins and lemons, with pricing power, brand loyalty, and demand growth on their side. The weak part is equally clear: grapefruit and the Florida/Texas footprint, in structural decline from disease and weather — and USDA's April 2026 forecast has all three non-orange types modestly lower again in 2025–26.[2] The variables that will decide the next decade are (1) whether HLB research delivers resistant varieties or an effective treatment, (2) how tightly California water rules (SGMA, drought) squeeze acreage and cost, (3) labor and immigration policy, and (4) import competition in lemons and limes. The central underwriting trap is confusing gross acreage or land value with durable free cash flow. Returns should favor operators that control water, keep trees healthy, diversify geography and customers, and participate in packing or branding rather than relying on farm-gate commodity sales — and the cleanest way to play the growth side remains private, with Limoneira the lone, imperfect, public proxy.
