Pinus sylvestris
Pinus sylvestris is associated with broad eurasian range with strong provenance variation. Two short blue-green needles; orange bark on upper trunks. Often called Scotch pine; locally short-lived where pine wilt is prevalent. Choose stock and planting space for the species rather than using a generic pine irrigation or pruning prescription.
Profile
- Habitat
- Broad Eurasian range with strong provenance variation
- Identification
- Two short blue-green needles; orange bark on upper trunks
- Siting
- Often called Scotch pine; locally short-lived where pine wilt is prevalent
- 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 on suitable soils
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.
Use well-drained soil and deep establishment watering; supplement severe drought but investigate disease if a tree browns rapidly despite adequate moisture. Check moisture below the mulch and across the expanding root zone before rewatering.
Problems to watch
- Pine wilt disease
- Pine sawflies
- Dothistroma needle blight
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
- Windbreaks where suitable
- Forestry and Christmas trees
