Pinus nigra
Pinus nigra is associated with southern europe and adjacent regions; subspecies vary. Two stiff dark needles per bundle and a dense crown. Austrian pine is a commonly planted form; provenance influences performance. Choose stock and planting space for the species rather than using a generic pine irrigation or pruning prescription.
Profile
- Habitat
- Southern Europe and adjacent regions; subspecies vary
- Identification
- Two stiff dark needles per bundle and a dense crown
- Siting
- Austrian pine is a commonly planted form; provenance influences performance
- 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
- Good once established, but drought promotes disease
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.
Provide deep establishment watering and supplemental water in prolonged drought; avoid routine overhead wetting that favors needle disease. Check moisture below the mulch and across the expanding root zone before rewatering.
Problems to watch
- Diplodia tip blight
- Dothistroma needle blight
- Pine wilt where locally important
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
- Large windbreaks
- Specimen and forestry plantings
