Propagation & Care
Seed collectionCollect fresh nuts October–December.
StratificationRecommended: 30–60 days cold stratification in slightly damp coir, up to 90 if the nuts are being held anyway.
PropagationPlant whole nut 1–2 inches deep after stratification.
Container progressionNut → D60 Deepot / treepot → Field planting.
Nursery wateringEven moisture. Do not dry completely.
LightStrong light after germination. Harden to full sun.
OutplantingBest age 6–18 months. Plant November–February.
Establishment Watering
- Year 1: 10–15 gallons every 7–10 days during dry periods.
- Year 2: 15 gallons every 2–3 weeks in drought.
- Year 3: monthly drought support if needed.
Field notesDo not plant pecan as an upland prairie tree. Plant it where water and deep soil already want a pecan.
