Though primarily known for its sweet pecans, this large deciduous tree from eastern and southern North America and Mexico also has ornamental virtues. It is a tall, beautiful tree with attractive compound leaves, a tall straight trunk and furrowed, gray-brown to brown-black bark. Many cultivars have been selected for flavor, hardiness, earliness of ripening, and other characteristics.
Trees generally take from 15 to 20-years before they are fruit-bearing. Harvest takes place very late in the fall season, and the larger the tree the more prolific its nut production. Pecans have smooth, woody, oblong shells that are sandy brown in color. When cracked they bear oblong, ribbed nutmeats that are sweet and flavorful. These taste best when lightly toasted.
Pecan is a bottomland tree and likes full to part sun and moist, rich, slightly acidic soil with average drainage. Transplanting can be difficult because of its long taproot. Use as a crop or shade tree.
Best grown in humusy, rich, moist, well-drained soils in full sun. Difficult to transplant because of its deep taproot. If grown for nut production, plant at least two different varieties for best cross-pollination. Nut production can be sparse in the northern part of its growing range, particularly when spring is late and summer is cool. May be grown from seed, but it normally takes 8-10 years for a young tree to bear a nut crop.

|Germination||Seeds can be sown in autumn outside for spring germination or stratified and sown inside in the end of winter.|
If seed sown inside:
1. Soak seeds in very warm water for 3 days. Change water daily.
2. Mix with moist vermiculite or sterile sand, place in bag or container and keep in the fridge for 90 days at +2-+4C (36-40F). Periodically check and keep the sand or vermiculite moist.
3. Plant seeds after this stratification inside 2-4 cm (1-2") deep in pots or outside after the last frost.
It will germinate easily under favorable conditions, provided they have good soil and adequate water.
