Soil type: Prefers deep, fertile, well-drained loamy soils with slightly acidic to neutral pH. Avoid shallow or compacted soils.

Watering frequency: Requires consistent watering during establishment and fruiting; mature trees tolerate short droughts but benefit from supplemental watering during dry seasons.

Light exposure: Full sun is essential for optimal growth and nut production; needs at least 6-8 hours of direct sunlight daily.

Temperature requirements: Thrives in temperatures between 18°C–32°C (65°F–90°F); dormant trees tolerate down to -9°C (15°F).

Fertilization: Use high-nitrogen fertilizers in early spring; zinc supplementation may be necessary for optimal nut development.

Pruning: Prune in late winter to remove dead or crossing branches and to establish a strong central leader; avoid heavy pruning of mature trees.

Common pests: Watch for pecan weevils, aphids, scale insects, and hickory shuckworms; fungal diseases like pecan scab may occur in humid regions.

Other care practices: Grafting is common for improved nut varieties. Ensure ample spacing between trees (minimum 12 meters) to accommodate full crown spread and air circulation.
