We’ve had quite a journey with our mighty oaks. We had two that were about 30 feet apart in the back yard. One larger and wider, one tall and existing fine on the perimeter of the other. Both were about 100 feet tall. I measured with a drone.
last year we had a pool built and it stressed out...
Does this look like insect damage? Strange dark holes going up the side of the trunk?
Tree was planted last summer. Gets good water and full sun.
Thoughts?
