I have several oak trees that seem to be splitting in cetain areas of
the tree trunk.
Most of the spliting starts at the ground and go about to the first
branch, which is at 5 ft.
There is about eight trees with this problem some are worse than
others.
The trees are in north eastern ohio on a farm and most are 15 years
old.
If anyone has any idea what this might be, please respond quickly
Thanks
