o.uk...
For the sceptics - if you put preservative in a hole in the middle of the
post, where do you think it goes if it doesn't soak into the wood?
Sure, it won't do a good job of protecting the outside of the post - but
that will be the bit the 1 minute pressure treatment did. And if the
outside rots away leaving a solid core - well, that's better than the
outside and the inside rotting...
Another thing that helps is to put plastic paint cans over the tops of
posts.
Covers the end grain where they often rot.

A carved wooden finial looks better and rots in the place of the post.
