Pecan
Carya illinoinensis
treePecan is a large, deciduous tree native to North America that produces delicious nuts enclosed in a hard shell. These trees can live for over 100 years and grow quite tall, making them a long-term investment for the home or commercial grower. Pecans are valued both for their culinary uses and as ornamental shade trees.

Establishment (Years 1-3)
3 yearsYoung tree develops strong root system and main scaffold branches; minimal nut production expected
Water deeply and regularly, prune to develop strong framework, apply mulch, avoid heavy nitrogen fertilization, stake if needed for wind protection
Juvenile Growth (Years 4-7)
4 yearsTree continues expanding canopy and developing branch structure; begins bearing small nut crops
Continue training and pruning for open vase shape, maintain consistent watering, monitor for pests and diseases, thin excessive flower clusters to conserve energy
Flowering (April-May)
3-4 weeksMale catkins and female flowers appear on branches; wind pollination occurs
Ensure adequate water and nutrients, avoid pruning during flowering, minimize stress, maintain balanced soil nutrition for good pollen viability
Nut Development (June-August)
2-3 monthsNuts grow inside fuzzy hulls, kernel develops inside hard shell; trees require peak water availability
Provide consistent deep watering (1-2 inches per week), apply balanced fertilizer, control pests and diseases aggressively, avoid stress conditions
Maturation & Harvest (September-November)
2-3 monthsHulls split and darken, nuts fall to ground naturally; kernels reach full size and flavor
Collect fallen nuts promptly, clean and dry thoroughly (cure at 95-105°F for 2-3 weeks), store in cool dry location, manage alternate bearing patterns

Common Pests
-
Early harvest, orchard sanitation, trunk banding, insecticide applications in late August-September, pheromone traps for monitoring
-
Prune out infested branches, remove caterpillars by hand, encourage natural predators, spray Bacillus thuringiensis if severe
-
Sanitation of fallen nuts and debris, cover sprays starting in early August, resistant varieties where available
-
Water spray to dislodge, insecticidal soap, neem oil, encourage natural predators like ladybugs
-
Use resistant rootstocks, manage stress through proper irrigation and nutrition
Uses
Nuts for eating and cooking

Harvest Tips
Nuts are ready when hulls split naturally and nuts fall to the ground, typically September-November depending on variety and location. Use a mechanical tree shaker or hand-collect fallen nuts. Clean off hulls promptly to prevent mold. Cure nuts at 95-105°F for 2-3 weeks before storage. Store in cool (50-60°F), dry conditions (under 7% moisture). Wear gloves when handling to avoid staining.
Fun Facts
- 🌱 Pecan trees are alternate-bearing, meaning they produce heavily one year and lightly the next; proper thinning of flower clusters can help regulate this pattern.
- 🌱 It takes about 20 years from seed to produce a mature, healthy pecan tree, which is why grafted nursery trees are preferred for faster production.
- 🌱 Pecans are entirely native to North America and were a staple food for Native Americans long before European colonization; the word 'pecan' comes from the Algonquian word 'pacane.'
