Pecans typically cost 30% to 50% more per pound than walnuts at retail, and the reasons come down to biology, geography, and sheer volume of global supply. Walnuts are produced on a massive scale worldwide, while pecans remain a niche crop grown almost exclusively in the United States and Mexico. That supply gap, combined with the pecan tree’s frustrating growing habits, keeps prices stubbornly high.
Global Supply Tells Most of the Story
The single biggest factor is how much of each nut the world produces. China alone grows roughly 1.55 million metric tons of walnuts per year, accounting for about 55% of the global supply. Add in production from the U.S., Chile, and other countries, and walnuts are one of the most widely available tree nuts on the planet.
Pecans are a different picture entirely. The United States produces around 80% of the world’s pecans, with Georgia, New Mexico, and Texas leading the way. China’s pecan output is growing but still tiny: roughly 6,000 metric tons in 2025, compared to its 1.55 million metric tons of walnuts. That’s a ratio of more than 250 to 1. When supply is that limited relative to demand, prices stay elevated.
Pecan Trees Are Slow and Unpredictable
Pecan trees take 5 to 10 years after planting before they produce a commercial harvest. That’s a long investment horizon for growers, who need to maintain the trees, irrigate, and manage pests for years before seeing any return. Walnut trees have a similar wait, but the payoff is entry into a much larger, more liquid global market.
More importantly, pecans have a pronounced “alternate bearing” cycle. Trees tend to swing between a heavy crop one year and a light or nonexistent crop the next. This isn’t a minor fluctuation. Research from the American Society for Horticultural Science describes alternate bearing as “especially severe” in pecans compared to other fruit and nut trees. During a heavy “on” year, the tree dumps so much energy into producing nuts that it depletes its carbohydrate reserves, particularly in the roots. The result is a poor or empty “off” year that follows. Making matters worse, the bumper crop from an on year often produces lower-quality kernels, so a big harvest doesn’t necessarily mean a big payday. Over time, high production in good years does not compensate for the losses in bad years, meaning the average annual yield per acre stays lower than growers would like.
Pecans Need Specific Growing Conditions
Pecan trees are picky about where they’ll thrive. They need at least 200 frost-free days per year, temperatures ideally between 75°F and 95°F, well-drained sandy loam soil, and plenty of rainfall or irrigation. They can handle brief cold snaps down to about 10°F, but late spring frosts can destroy blossoms and wipe out an entire season’s yield. This limits commercial pecan production to a relatively narrow band of the southern United States and parts of northern Mexico.
Walnuts are more geographically flexible. They grow commercially across large portions of China, Central Asia, South America, and the western United States. That geographic diversity means walnut production isn’t as vulnerable to a single drought or frost event, and the sheer number of growing regions keeps supply robust and prices more stable.
Harvesting Costs Add Up
Harvesting pecans is expensive. Contract harvesters using mechanized equipment typically charge 50% to 70% of the crop as payment for their services, and that fee often includes pre-harvest work like pruning, mowing, and pest spraying. For smaller or scattered native pecan groves, at least half the harvest goes to hand pickers. Either way, the grower is giving up a large share of the crop before it ever reaches a buyer.
Walnut harvesting faces similar challenges, but the economics work differently at scale. California’s massive walnut orchards are designed for efficient mechanical harvesting, with uniform tree spacing and flat terrain. Pecan operations, especially in the Southeast, are more fragmented and include many smaller native groves where equipment needs modification and coverage tops out at about 10 to 12 acres per day regardless of yield.
Cold Storage Is Non-Negotiable
Pecans have an extremely high oil content, and about 93% of that oil is unsaturated. That’s great nutritionally but terrible for shelf life. At room temperature (around 70°F), shelled pecans last only about 3 months before rancidity sets in. In-shell pecans fare slightly better at 4 months. To preserve quality, pecans need to be stored at 32°F or below, where shelled nuts can last up to a year and in-shell nuts up to 18 months. For storage beyond that, freezing is required.
Humidity control matters too. Shelled pecans need to be kept at 65% to 70% relative humidity to maintain their ideal 3% to 4% moisture content. Too much humidity causes mold; too little dries the kernels out. When nuts finally come out of frozen storage, they need to be thawed slowly, raised gradually to 45°F or 50°F before exposure to warmer air. All of this cold chain infrastructure, from refrigerated warehouses to careful tempering, adds cost that gets passed along to the consumer.
Walnuts also require cool storage, but their slightly different fat profile (higher in polyunsaturated fats, particularly omega-3s) and the massive scale of walnut processing facilities mean storage costs per pound are generally lower.
Trade Policy and Export Dependence
For nearly a decade, 50% to 70% of Georgia’s pecan crop was exported to China. When the U.S.-China trade war introduced an additional 15% tariff on nuts, it disrupted a market that the American pecan industry had grown deeply dependent on. Higher tariffs raised the cost of U.S. pecans for Chinese buyers, reducing export volumes. Finding alternative markets proved difficult because no other single country could absorb the volume China had been purchasing.
This kind of export concentration creates price volatility. In years when trade flows freely, strong Chinese demand pushes domestic prices up. When tariffs or trade disputes interrupt that flow, growers face a surplus they can’t easily redirect, which can temporarily depress prices but also discourages new planting. The long-term effect is an industry that stays smaller and less stable than the walnut industry, which benefits from diversified production across multiple countries and isn’t as dependent on any single trade relationship.
What the Price Gap Looks Like
Wholesale prices for 50-pound sacks of improved pecan varieties averaged about $150 between January and October 2025, down from $174 the year before. That translates to roughly $3.00 per pound at wholesale before any processing, packaging, or retail markup. Retail pecan prices commonly land between $8 and $14 per pound depending on variety and whether they’re sold as halves or pieces (halves command a premium partly because they have a longer shelf life than broken pieces, which expose more surface area to air and go rancid faster).
Walnuts, by contrast, typically retail for $5 to $8 per pound. The gap narrows or widens depending on the harvest year, trade conditions, and whether pecans are in an on or off bearing cycle, but pecans have consistently been the pricier nut for decades. The combination of limited global supply, finicky trees, expensive harvesting, and demanding storage requirements makes it unlikely that gap will close anytime soon.
