Red Pine

Red Pine is associated with northeastern and north-central north american forests. Two long needles that tend to snap when bent; reddish plated bark. Performs best in full sun on drained soils with room for a tall trunk. Choose stock and planting space for the species rather than using a generic pine irrigation or pruning prescription.

Pinus resinosa · Northern two-needle pine

Profile

Habitat
Northeastern and north-central North American forests
Identification
Two long needles that tend to snap when bent; reddish plated bark
Siting
Performs best in full sun on drained soils with room for a tall trunk
Light
Full sun; protect the future root zone from compaction and grade changes.

Water & soil targets

Moisture (VWC)
Site-calibrated; varies by soil and rootstock
Salinity tolerance
Prefer low-salinity irrigation; salt spray and deicing runoff can burn needles and impair roots.
Drought tolerance
Moderate to good once established

Optimal root measurement depth

8–18 in

Most absorbing tree roots live in the upper 12–18 inches, out toward the drip line. Typical guidance; confirm with a soil probe on site.

Maintain establishment moisture and supplement protracted drought; avoid wet, compacted root zones and excessive overhead wetting. Check moisture below the mulch and across the expanding root zone before rewatering.

Problems to watch

  • Diplodia shoot blight
  • Pine needle diseases
  • Bark beetles under stress

Stress signs

  • Abnormal browning of current foliage or branch tips
  • Reduced candle extension and a thinning crown
  • Premature needle shedding beyond normal older-needle turnover

Where you'll find it

  • Timber plantations
  • Large northern windbreaks
