Eastern White Pine
Pinus strobus
Family: Pinaceae
Hardiness: USDA Zones 3-8
Eastern White Pine is the tallest native conifer in eastern North America, historically growing over 200 feet. It is highly susceptible to wind damage due to its height and shallow root system, and is vulnerable to ice damage. White Pine is also affected by white pine blister rust and white pine weevil.

Recovery Guides
Eastern White Pine Ice Storm Recovery
Recovery guide for Eastern White Pines after ice storms, focusing on leader damage and crown restoration.
- 1
Leader Assessment
The most critical damage is loss of the central leader. Without it, the tree loses its characteristic pyramidal form. Check if a lateral branch near the top can be trained as a new leader.

Train a New Leader
If the leader is broken, select the strongest lateral branch near the break point. Gently stake it upright using a flexible splint tied loosely. It will naturally assume dominance over 2-3 years.

Remove Broken Branches
Prune broken branches cleanly at the branch collar. White pines produce significant resin at wound sites, which helps seal against infection.
- 4
Thin Damaged Crown
If more than 50% of the live crown is damaged, the tree will likely survive but will have an irregular form. Accept the new shape rather than attempting heavy corrective pruning.

Watch for Weevil
White Pine Weevil attacks the terminal leader. Fire-or ice-damaged trees with multiple leaders are particularly attractive to weevils. Monitor leader tips in spring for wilting.
Eastern White Pines are particularly vulnerable to ice storms. Their flexible branches can bend under ice load, but leaders and upper crown branches often snap.
