Piñon pine
Pinus edulis
- Family:
- Pinaceae
- Elevation:
- 5,000 ft – 7,500 ft
- Region:
- Southwest
New Mexico's state tree — a compact, rounded pine that produces the prized piñon nut in good years. Paired with juniper across millions of acres of high desert.
Care · tuned to the Southwest
Water
Drought tolerant once established; a deep monthly soak in the first two summers speeds establishment, then rainfall. Overwatering invites root disease.
Sun & exposure
Full sun.
Soil
Rocky, alkaline, sharply drained. Intolerant of wet or compacted ground.
In the Southwest
Vulnerable to piñon ips bark beetle during prolonged drought — keep trees vigorous with occasional deep watering in extreme dry spells, and never pile fresh-cut piñon wood beside living trees (it breeds beetles). Nut crops are heavy only every few years.
Common problems & fixes
Piñon ips bark beetle — drought-stressed trees brown and die fast
Fix — Keep trees deeply watered during drought to hold vigor, and remove and destroy infested wood promptly.
Black stain root disease — a fungal root disease spread by root grafts and insects
Fix — Avoid root wounding and soil disturbance, minimize drought stress, and remove infected trees.
Pets & toxicity
Non-toxic.
Easy to confuse with
- Ponderosa pine (P. ponderosa) — long needles, higher elevation
- Junipers — scale leaves, not needles
