The message
from Iain Douglas contains these words:

I've an oak tree about 25' tall growning at the side of my
garden. I want to raise the level of the garden about 18" on that side.
Will the oak survive if I cover the lower 18" of bark or do I need to
protect it ?

You shouldn't earth-up the bole of an oak tree or it will probably get
disease in. (Theoretically, you shouldn't earth-up any tree, but some
don't mind too much: willows especially.)

There are several trees in a nearby park that have been earthed up and
are dint
really well. I'm not sure what they are thought.

At the moment......

As a one-time partner in a tree-felling and surgery business (we all got
too old and gave it up eventually, having started it as Rover Scouts in
the '50s) I can confidently predict that unless they are willows, alder,
etc or something similar, they will have problems sooner or later.

A lot of the trees we were called to 'sort out' had become diseased
because of earthing-up.
