Author of The Last Prince of the Mexican Empire, etc.

It opens, as the darkest do, with a sunny scene of innocence. Clustered along river bottoms in what would one day become Texas, groves of pecan trees rained down their bounty for wildlife and indigenous peoples. For centuries, pecans were their superfood, dense with calories and nutrition. In the 16th century, Alvar Nuñez Cabeza de Vaca, the conquistador who shipwrecked en route to Florida and wandered west, found the Guadalupe River "a river of nuts" although he had no word for them but "walnut." The name "pecan" dates from the late 18th century.
The pecan did not do well further north. Thomas Jefferson planted some 200 pecan trees in Monticello; none survive. Where nuts were wanted, European walnut varieties proved more popular and versatile, so the pecan was left to do what it had always done, thrive in its wild state along river bottoms, mainly in what is today Texas. Notes McWilliams, "unlike any other fruit-bearing tree in the age of cultivation, the pecan managed to evade the cultivating hand of man for centuries after humans began exploiting it for food."
In the 19th century, as ranching and cash crops such as cotton, corn and wheat spread across the South and Midwest, many pecan trees disappeared; nonetheless, a large number of groves survived, especially in Texas, because they clung to riverbanks and bottoms, and proved able to survive floods that other crops could not.
Farmers found wild pecans not only delicious as snacks for themselves, but good pig feed, and bags of them, easily gathered, could be sold in new markets in San Antonio, Galveston, and New Orleans. In the second half of the 19th century, Texas took the lead in pecan production, but not from formal orchards; for the most part, farmers gathered wild pecans.
How to sell more pecans? The market wanted uniformity, thin shells, and dense nut meats. Even the most magnificent pecan tree's seed, however, would not "come true," that is, bring forth a tree producing equivalent quality nuts. The solution was grafting. As early as 1822 one Abner Landrum detailed his own successful experiments with pecan grafting in the American Farmer. It seems no farmer bothered to emulate that experiment. The market for pecans was still marginal and, as McWilliams ventures, "it was simply more macho to run a ranch with cattle than to turn that land over to pecans."
In the mid-century 19th century, in the Oak Alley Plantation in Louisiana, a slave gardener named Antoine successfully grafted an orchard of more than 100 fabulously productive pecan trees. Decades later, the plantation's new German owner, Herbert Bonzano, brought the nuts of those grafted pecans to Philadelphia's 1876 Centennial Exposition. And thus, like so many other fruits before it, the pecan was at last, if slowly, on the road to industrial production a road, like that to Hell, paved with good intentions.
For a time, farmers relied on wild pecans, resisting experts' advice to graft pecans, perhaps out of innate conservatism and a reluctance to becoming dependent on nurserymen. Attitudes soon changed. After a series of insect plagues in the last three decades of the 19th century decimated major cash crops, the USDA championed chemical insecticides that, "lo and behold, worked." Writes McWilliams, "The USDA was no oracle, but as pecan farmers recognized, history showed it could make life much easier for those who tilled the soil for a living. So long as they would listen." Listen they did.
The 20th century brought increasing industrialization in pecan production. After World War I, writes McWilliams, "pecan trees were becoming carefully managed commodities rather than natural aspects of the southern landscape." As for shelling, an important source of employment in San Antonio in the 30s, after some labor unrest, this was given over to machines.
In World War II the U.S. government gave the pecan industry a push, promoting the nuts as nutritious replacements for meat; and after imposing price ceilings to help promote consumer demand, buying up millions of pounds of surplus pecans (many fed to schoolchildren). By the late 1940s, pecans were no longer holiday treats or just for pralines, they were in cakes, cookies, pies, and even tossed into salads. McWilliams: "The aristocrat of nuts had become a commoner."
McWilliams brings the pecan through
the rest of its 20th century history with mail order, frozen
foods, processed foods, chain restaurants, granola, and ice cream;
its oil extracted for lubricants in clocks and guns, its wood
milled for basketball court flooring, its shells collected for
mulch, barbecue chips, plywood, pesticides, and more. By 2011,
when the author tours a Texan pecan farm, he is stuck with dark
Oh, but it gets stranger. The money isn't so much in the pecans as it is in shipping trees from the nursery to China. In 2001, Chinese did not have a word for pecan. Today pecans are a popular health food in China, available everywhere from airports to gas stations. It seems a question of time before the Chinese outstrip the U.S. in pecan production.
The future of the pecan, a "chemically
saturated activity," whether in the U.S. or China or elsewhere,
looks grim. Arsenals of insecticides are increasingly necessary
to combat aphids, beetles, weevils and more. These chemicals
also threaten bees and other pollinators (and without them, our
food supply as we know it may collapse). Plant diseases are also
becoming increasingly resistant to chemical assault. The soil
degrades. At some point perhaps when China has become the
top producer; perhaps when some insect or fungus has wiped out
enough orchards; or in the wake of some ecological or economic
jolt it may become unprofitable to continue producing pecans
in the U.S., the grafted and chemically attended ones for the
mass market, that is.
