Oak – Losing Bark, Trunk Rotting
Q: I have a white oak which is losing bark and there’s a white chalky residue present where the bark is falling off. Can you identify the problem and advise a remedy?
A: My bet is that water is getting into the space between the two trunks and rotting has begun. There’s not much you can do to remedy the situation.
You really need a consulting arborist to verify my observation.
Don’t park underneath!
