Eastern White Pine
Pinus strobus
The tall, soft-needled 'king pine' of the Northeast, with five needles per bundle and a graceful, layered form. Sensitive to road salt, air pollution, and de-icing spray, often showing winter needle browning. White pine weevil deforms leaders, and white pine blister rust affects it where currants grow nearby.

Common questions
Why did my white pine's needles turn brown after winter?
White pine is very sensitive to road salt, wind, and pollution, which scorch needles over winter. Sudden uniform browning near roads usually points to salt spray rather than disease.
Can I prune a white pine to keep it smaller?
You can lightly shear the soft new 'candles' in spring to densify growth, but it does not respond well to hard cuts into old bare wood, which will not resprout.
