Commercial pineapple production in the United States is concentrated in Hawaii and Puerto Rico, with Hawaii being the only state on the mainland-and-islands map that has supported large-scale farming of the fruit. Florida grows pineapples on a much smaller, mostly hobbyist and niche-farm scale, and a handful of other warm-climate states can sustain individual plants or small plots. The story of where pineapples grow in the US is also a story of dramatic decline, because domestic production has shrunk enormously over the past several decades while imports, particularly from Central America, have filled the gap.
Hawaii’s Rise and Steep Decline
For most of the twentieth century, Hawaii was the center of world commercial pineapple production. Plantations run by companies like Dole and Del Monte made the islands synonymous with canned pineapple. At its peak around 1960, Hawaii produced about 884,000 tons of pineapple fruit per year. By 1996 that figure had dropped to roughly 347,000 tons, and the decline has continued since then.1Acta Horticulturae. THE HAWAIIAN PINEAPPLE INDUSTRY The industry’s downsizing began in earnest with the closure of the Del Monte cannery in 1985, and over the following years production shifted away from canned products toward fresh-market fruit.
The reasons were primarily economic. Labor costs in Hawaii are far higher than in competing tropical countries, and as global shipping infrastructure improved, it became cheaper to grow pineapples in places with lower land and labor costs and ship them to the American market. Today, Hawaii still produces fresh pineapples on Maui and Oahu, most visibly through the Dole Plantation on Oahu and Maui Gold operations, but the acreage is a fraction of what it once was. The state’s pineapple industry is now more of a boutique agricultural sector and tourist attraction than a commodity powerhouse.
Puerto Rico’s Ongoing Production
Puerto Rico, a US territory with a fully tropical climate, continues to grow pineapples commercially. Farms are spread across several municipalities, including Guánica, Lajas, ManatÃ, and Santa Isabel, and the University of Puerto Rico maintains an agricultural experiment substation in Isabela that works on pineapple research.2The Journal of Agriculture of the University of Puerto Rico. Detection and incidence of pineapple heart rot disease caused by Phytophthora nicotianae in commercial farms of Puerto Rico Puerto Rico’s output does not rival what Hawaii produced in its heyday, but the island’s year-round warmth and established farming infrastructure make it one of the few places under the US flag where pineapple cultivation is straightforward.
Puerto Rican pineapple farming faces its own challenges, though. A survey of commercial fields found that heart rot disease caused by the water mold Phytophthora nicotianae was present in most evaluated farms, with an average disease incidence close to 29% across roughly eight infected hectares.2The Journal of Agriculture of the University of Puerto Rico. Detection and incidence of pineapple heart rot disease caused by Phytophthora nicotianae in commercial farms of Puerto Rico Heart rot can devastate a planting, rotting the center of the fruit and killing young plants. Managing it requires careful attention to drainage and, in some cases, chemical treatments.
Florida and Other Mainland States
Florida is the mainland state most commonly associated with pineapple growing, and it does have a real, if limited, pineapple history. In the late 1800s and early 1900s, the area around what is now Palm Beach County and the Indian River region had small pineapple farms. Freezes and competition from Cuban imports largely killed off that industry, but south Florida’s climate, particularly in the southern tip of the peninsula and the Keys, still supports pineapple plants. You can find small farms and home growers throughout Miami-Dade and Broward counties.
The critical limitation is frost. Pineapples are a tropical plant that grows best in frost-free climates.3ISHS Acta Horticulturae. CLIMATIC ADAPTATION IN FRUIT CROPS Even a light freeze can damage or kill a pineapple plant, and central and northern Florida get freezing temperatures often enough to make commercial pineapple farming impractical. Southern Texas, coastal southern California, and parts of the Gulf Coast can sustain pineapple plants in the ground during mild winters, but a single hard freeze event can wipe out years of growth. This makes commercial production outside of Hawaii and Puerto Rico essentially unviable on the mainland, though individual plants and small plots can thrive in protected microclimates.
Why Cold Is the Dealbreaker
Pineapple’s intolerance of cold is not just a matter of preferring warm weather. Nearly all commercial pineapple varieties suffer tissue damage after just 24 hours of exposure to temperatures around 4°C (roughly 39°F). That is not even freezing, just cold enough to damage leaf tissue and halt growth.4PLOS ONE. Transcriptome Profiling of the Pineapple under Low Temperature to Facilitate Its Breeding for Cold Tolerance The problem is compounded by the plant’s long production cycle. Even the shortest cycle from planting to fruit harvest is about 14 months, which means a pineapple plant growing in any subtropical region will encounter cold stress at least once during its life.
Researchers have identified cold-tolerant pineapple genotypes. One cultivar called “Shenwan” was selected specifically for its ability to survive exposure to 4°C for up to seven days and resume normal growth afterward.4PLOS ONE. Transcriptome Profiling of the Pineapple under Low Temperature to Facilitate Its Breeding for Cold Tolerance Work on cold tolerance in pineapples is ongoing in subtropical growing regions around the world, and if hardier varieties become available, they could theoretically push the range of viable pineapple cultivation further into the mainland US. For now, though, that possibility remains limited to research plots rather than commercial farms.
How Pineapples Handle Water
One thing that sets pineapples apart from most fruit crops is their remarkable water efficiency. Pineapples use a specialized form of photosynthesis called crassulacean acid metabolism, or CAM, which flips the normal pattern of gas exchange. Most plants open their leaf pores during the day to absorb carbon dioxide, losing a lot of water to evaporation in the process. Pineapples do the opposite: they open their pores at night, when the air is cooler and humidity is higher, capturing carbon dioxide and storing it as an acid. During the day, with pores closed, they convert that stored carbon dioxide into sugars.5Acta Horticulturae. PHOTOSYNTHETIC CRASSULACEAN ACID METABOLISM IN PINEAPPLE: DIEL RHYTHM OF CO2 FIXATION, WATER USE, AND EFFECT OF WATER STRESS
The result is dramatic water savings. Under controlled conditions, pineapple plants fix more than 70% of their daily carbon dioxide at night, and they transpire only about 6% of the water that a wheat crop would use when compared on a per-unit-of-soil basis.5Acta Horticulturae. PHOTOSYNTHETIC CRASSULACEAN ACID METABOLISM IN PINEAPPLE: DIEL RHYTHM OF CO2 FIXATION, WATER USE, AND EFFECT OF WATER STRESS Genomic research has shown that pineapple’s CAM photosynthesis evolved not by acquiring brand-new genes but by rewiring the timing of genes that already existed in the plant’s ancestors, linking them to the circadian clock so they activate at night instead of during the day.6PubMed Central. The pineapple genome and the evolution of CAM photosynthesis
This water efficiency is one reason pineapples can grow in drier subtropical zones that would stress many other tropical fruits. Hawaii’s leeward pineapple fields, for instance, receive far less rainfall than the islands’ windward sides, but the plants manage well because they are so conservative with water. It also means that home growers in drier parts of southern Florida or southern California can keep pineapple plants alive without heavy irrigation, which helps explain the plant’s popularity as a backyard curiosity even in areas where commercial farming is not feasible.
Soil Preferences and Nutrient Quirks
Pineapples are unusual among crop plants in their tolerance for acidic soils. Most food crops struggle when soil pH drops much below 5.5, but pineapples actually thrive in very acidic conditions. Research on controlling root and heart rot diseases has shown that a soil pH below 3.8, well into the range that would kill most crops, does not adversely affect pineapple plant growth.7Australian Journal of Experimental Agriculture and Animal Husbandry. Soil application of elemental sulphur as a control of Phytophthora cinnamomi root and heart rot of pineapple In fact, keeping the soil highly acidic through applications of elemental sulfur has been used as a disease-management strategy, because the Phytophthora organisms that cause root rot cannot function well in such low-pH environments.
This acid tolerance comes with a nutritional catch. Pineapples grown in very acidic soils with high manganese levels often develop iron deficiency, because manganese interferes with how the plant uses iron. The result is chlorosis, a yellowing of the leaves that stunts growth and reduces fruit quality. Commercial growers typically manage this with regular iron sprays directly on the foliage, and research has found that without those sprays, no calcium-based soil amendment could prevent severe iron deficiency in acid soils.8Acta Horticulturae. LIME, GYPSUM, AND BASALTIC DUST EFFECTS ON THE CALCIUM NUTRITION AND FRUIT QUALITY OF PINEAPPLE For backyard growers in the US, this is worth knowing: if your pineapple plant’s leaves are turning yellow from the center outward, the problem may not be overwatering or sunburn but an iron issue that a simple foliar spray can fix.
Pests That Limit US Production
Beyond cold and economics, pineapple growers in the US contend with a pest complex that can be difficult to manage organically. The most economically damaging disease is mealybug wilt of pineapple. It is caused by a group of viruses transmitted by pink pineapple mealybugs, tiny sap-sucking insects that colonize the base of the plant’s leaves and roots.9Horticulturae. Ecologically Based Management of Pineapple Mealybug Wilt: Controlling Dysmicoccus brevipes Mealybug Populations with Salicylic Acid Analogs and Plant Extracts Infected plants wilt, turn reddish, and eventually die. In large-scale production systems, insecticides are the standard control method.
The relationship between mealybugs and ants makes things worse. Ants farm mealybugs for their sugary excretions and actively protect them from predators. Research has shown that the presence of ants is correlated with a faster rate of virus spread when mealybugs are feeding on plants.10PubMed. Transmission of Pineapple Mealybug Wilt-Associated Virus by Two Species of Mealybug (Dysmicoccus spp.) This means that controlling ants is almost as important as controlling the mealybugs themselves, a detail that matters for both commercial growers and home gardeners. In Hawaii, ant management around pineapple fields has been a long-standing part of integrated pest management programs.
Recent research has explored alternatives to conventional insecticides. Compounds related to salicylic acid, which triggers a plant’s own defense responses, reduced mealybug populations by 50% to 80% in trials and could offer a less chemically intensive option for growers.9Horticulturae. Ecologically Based Management of Pineapple Mealybug Wilt: Controlling Dysmicoccus brevipes Mealybug Populations with Salicylic Acid Analogs and Plant Extracts These plant-defense-boosting treatments are already used in other crop systems and may become part of the toolkit for US pineapple farmers looking to reduce pesticide use.
Why Almost Every Pineapple You Buy Is Imported
Despite Hawaii’s famous pineapple heritage, the vast majority of pineapples sold in the US today come from abroad. Costa Rica dominates the import market, followed by countries like the Philippines, Honduras, and Mexico. The rise of the golden pineapple variety, known commercially as MD-2, reshaped the global trade starting in the late 1990s. MD-2 is sweeter, less acidic, and more visually appealing than the older Smooth Cayenne variety that dominated the canned pineapple era. The introduction of MD-2 raised Costa Rica’s annual pineapple exports to the US market by more than 25%.11International Journal of Food and Agricultural Economics. Effect of “Golden Pineapple Innovation” on Costa Rica’s Pineapple Exports to U.S. Market: An Econometric Approach
MD-2 plants also outperform Smooth Cayenne in terms of growth. Studies comparing cultivar performance have found that MD-2 produces higher plant-weight increases than the traditional standard variety.12Agronomy Journal. Growth Indicators for Different Pineapple Cultivars Compared with the Current Standard ‘Smooth Cayenne’ in West Africa and Reunion Island Nutritionally, MD-2 also tends to have lower levels of antinutritional compounds like oxalates and phytates compared to Smooth Cayenne.13International Journal of Plant & Soil Science. Study of Potassium Fertilization on Some Antinutritional Factors in Two Pineapple Varieties Cultivated in Côte D’ivoire during Postharvest Storage The combination of better taste, better looks, and strong agronomic performance made MD-2 the global standard, and the countries that could produce it cheaply at scale captured the US market. Hawaiian and Puerto Rican operations simply cannot compete on price, which is why domestic production has continued its long slide.
Growing Pineapples at Home Across the US
Even if commercial US pineapple farming is limited to a couple of locations, home growing is popular in a surprisingly wide range of states. The trick is that pineapples adapt well to container culture. You can start a plant from the leafy crown of a store-bought pineapple by twisting it off, letting the base dry for a day or two, and planting it in well-draining acidic soil. In USDA hardiness zones 10 through 12, covering south Florida, southern coastal Texas, parts of southern California, Hawaii, and Puerto Rico, pineapple plants can stay outdoors year-round.
In zones 8 and 9, which include much of the Gulf Coast, parts of the Carolinas, and the inland Southeast, growers keep pineapple plants in pots on patios during warm months and bring them indoors or into a garage when temperatures threaten to drop into the low 40s Fahrenheit. Given that pineapple tissue can sustain damage at around 39°F, the margin for error is thin. A single forgotten night during a cold snap can set the plant back dramatically or kill it outright. Growers in zones 6 and 7 can still produce pineapples, but they need a sunny indoor spot, ideally a south-facing window or supplemental grow lights, for most of the year. The long production cycle means you might wait 18 to 24 months from planting a crown to harvesting a fruit, and the fruit will be smaller than what you find in the grocery store.
The payoff for patient growers is flavor. A fully vine-ripened pineapple, picked when it has reached peak sweetness rather than harvested green for long-distance shipping, is noticeably better than imported fruit. Homegrown pineapples also produce ratoon crops: after you harvest the main fruit, the plant sends up side shoots called “suckers” that can each grow a new fruit. A single plant in a favorable climate can keep producing for several years this way, making it one of the more rewarding tropical fruits for backyard cultivation in the warmer parts of the country.
The Outlook for Domestic Pineapple Farming
Interest in locally grown tropical fruit has been rising across the US as consumers pay more attention to food miles and supply chain resilience. Small farms in south Florida, particularly in the Homestead and Redland agricultural areas south of Miami, have begun marketing locally grown pineapples at farmers’ markets and through direct-to-consumer channels. These operations are tiny by global standards but they serve a niche of buyers willing to pay a premium for fruit that did not spend days in a refrigerated shipping container. Hawaii’s remaining pineapple farms similarly market themselves on provenance and quality, targeting tourists and specialty retailers rather than trying to compete on volume.
Whether cold-tolerant pineapple breeding could meaningfully expand where the crop grows on the mainland remains to be seen. The “Shenwan” genotype that survived a week at 4°C was identified in subtropical China, not bred for American growing conditions. Developing a commercially viable cold-tolerant variety that also meets American consumers’ taste expectations for MD-2-level sweetness would require years of breeding work. For the foreseeable future, pineapple farming in the US will remain a story of two islands, Hawaii and Puerto Rico, with a scattering of adventurous small growers in the warmest corners of the mainland keeping the tradition alive one crown at a time.
