The story
Pecan is North America's own nut, gathered along the rivers of Texas and the lower Mississippi by Caddo, Comanche and many other nations, who traded it widely; the name is Algonquian. The first grafted pecan was made by an enslaved gardener named Antoine on a Louisiana plantation in 1846, and that variety, 'Centennial', began the industry.
Planting
Full sun, deep soil, and a long hot summer; plant two varieties of opposite pollen timing. It becomes a huge tree, 70 feet; give it room or choose a yard-sized variety.
Growing
Water deeply and often through summer; pecans are river trees and drink hard while nuts fill. Zinc is the nutrient they most often lack.
Harvest and use
Shucks open in late autumn and the nuts drop; shake the limbs, gather daily, and dry a week before storing. Mature trees bear in alternate years.
What to watch for
Pecan scab in humid regions, pecan weevil, aphids, and squirrels.
