Norfolk Island Pine Trees

Norfolk Island Pine Tree

Anonymous added on February 8, 2018 | Answered

We have three very large mature Norfolk Island Pine trees outside our house and one of them has developed large holes in the bark about 30cm up from the base, they go in through the bark to a depth of 10 - 20cm and the wood inside is exposed and easy to see, a lot of the bark is peeling with more holes developing higher up. None of the the other trees have the same problem and I am concerned it is unstable. We live on the Central Coast one hour drive from Sydney Australia. Regards, Liz Mills

In this case it appears the structure of your trees may be compromised.
I do believe your tree is infected with some disease.

This link I found may be of some help.

I would suggest you have this tree inspected by a certified Arborist.
