5 Pecan Nut seeds, Carya illinoinensis, Calif.
Pecan trees grow best in rich, deep soil with full sun and hot, humid summers. The pecan is the state nut of Alabama, Arkansas, California, Texas and Louisiana, with Georgia, New Mexico and Texas having the largest commercial production. Trees for commercial production are usually grafted and sold in pots at tree prices. Pecan pie has long been a favorite in the South. Wild pecans were a treat for Native Americans. Several trees are needed for best nut harvest.
The pecan tree is a large tree, growing to 66–131 ft. in height, rarely to 140 ft. It typically has a spread of 39–75 ft. with a trunk up to 6.5 ft. in diameter. A 10-year-old sapling grown in optimal conditions will stand about 16 ft. tall.
Plant whole pecans a few inches deep in the fall and leave outdoors over the winter. Or, cold stratify the nuts at 34°to 41°F for 90 to 120 days in your refrigerator and plant in the spring. Seeds should be soaked for 24 hours prior to planting in soil.
They can be grown from USDA hardiness zones approximately 5 to 9, and grow best where summers are long, hot and humid. The nut harvest for growers is typically around mid-October.
