Q.peeling bark on birch trees
Someone peeled quite a bit of bark off of a few of our birch trees. They leafed the year afterward, but I’m concerned they’ll die. We have several birch trees that someone peeled the bark off and now the brown part of the trunk is showing. Should I paint this area white to protect them?
Allow the bark to heal naturally, do not apply any covering.
If you see signs of insects or possible disease use Neem Oil to treat the trunk and tree. Neem Oil works as both an insecticide and fungicide.
It is safe for people, pets and bees.
