Eastern White Pine
Pinus strobus
ConiferAbout Eastern White Pine
Eastern White Pine is the tallest conifer in eastern North America and was historically prized for ship masts during the colonial era. Its soft, fine-textured needles and graceful form make it a popular landscape tree. It grows rapidly and can live for over 200 years.
Quick Facts
How to Identify Eastern White Pine
- Soft, flexible needles in bundles of 5, bluish-green
- Long, slender, slightly curved cones 4-8 inches long
- Smooth, gray-green bark on young trees; dark, deeply furrowed on old trees
- Distinctive horizontal branching pattern with open spaces
- Feathery, wispy appearance from a distance
Care Guide
- Water regularly during dry periods, especially when young
- Avoid planting in exposed, windy sites or near road salt
- Prune candles in spring to promote denser growth
- Susceptible to white pine blister rust; avoid planting near currants or gooseberries
- Give adequate spacing; this tree grows large
Known Issues (8)
Southern Pine Beetle
HIGHThe most destructive bark beetle in the southeastern United States, capable of killing vast stands of pine trees during outbreaks. Adults bore into bark and introduce blue stain fungus that clogs water-conducting tissues.

Mountain Pine Beetle
CRITICALA native bark beetle responsible for massive die-offs of lodgepole, ponderosa, and whitebark pines across western North America. Climate change has expanded its range northward and to higher elevations. Outbreaks have affected tens of millions of acres.
Affecting 9 regions
Ips Bark Beetles
MODERATEA genus of bark beetles that attack stressed and weakened pines throughout North America. While they typically colonize dying trees, drought and overcrowding can trigger outbreaks that kill healthy timber.
Affecting 19 regions
Armillaria Root Rot
HIGHOne of the most widespread and destructive forest diseases in the world, caused by a complex of honey mushroom species. It attacks stressed trees through root contact and can persist in dead stumps for decades, infecting nearby healthy trees.

Diplodia Tip Blight
MODERATEA common fungal disease of pines, particularly Austrian and Scots pines in landscape settings. Spores infect new shoots as buds open in spring. Repeated infections progressively kill branches from the bottom of the tree upward.
Affecting 19 regions
Dothistroma Needle Blight
MODERATEA fungal disease of pines that causes premature needle loss and can significantly reduce growth and vigor. It affects many pine species but is especially damaging to Austrian, ponderosa, and Monterey pines. It has increased in severity with climate change.
Affecting 19 regions
Pine Wilt Disease
CRITICALA lethal disease of pines caused by the pinewood nematode, which is transmitted by pine sawyer beetles (Monochamus spp.). It causes rapid wilting and death of susceptible pine species, particularly non-native Scots pine and Austrian pine. The nematode clogs resin canals and destroys cells lining them, leading to cessation of resin flow and rapid desiccation. Trees typically die within weeks to months of symptom onset.
Affecting 19 regions
Cytospora Canker
HIGHA common fungal disease of spruce and other conifers that causes branch dieback, typically starting from the lowest branches and progressing upward. Colorado blue spruce and Norway spruce are especially susceptible. The fungus enters through wounds or stressed tissue. White resin bleeding on bark is a hallmark sign. Stressed trees are most vulnerable.
