HELP!!!* Our beautiful tree is three years old and just discovered that the bark on the trunk* in some spots have disappeared and paper thin and shredding.* We tried to see if there was active critters in the trunk but could not see any activity. We can see the grafts clearly inside the trunk.* It did have sap ouzing for a while and did not notice anything wrong with the trunk. That was about 4 weeks ago.
Any idea about what is going on would be greatly appreciated.
