Bark Ice Damage #934699

Asked June 08, 2026, 3:38 PM EDT

Our home on Black Lake has many pine trees with huge damaged bark. Should I treat the exposed areas or just leave them as they are? Thank you, <personal data hidden>

Expert Response

     The current recommendation is to NOT seal  the damaged areas of the tree bark but rather to remove any loose bark and then leave it alone to heal.  If less than 25% of the tree's circumference is affected it will probably recover.  If more than 50% of the circumference is involved the tree will likely die.  https://mortonarb.org/plant-and-protect/tree-plant-care/plant-care-resources/trunk-wounds-and-decay/

     The trees will be stressed and so promoting optimal growth conditions going forth including appropriate application of fertilizer and  water and monitoring for disease and pests will help support them in their recovery.

     Ultimately if the trees are severely injured, consultation with a certified arborist may prove helpful.  https://www.treesaregood.org/Find-an-Arborist
