Which is what I said. Taking the relative times available for
commercial treatment (as qucikly as possible) and amateur
use (over time) then the approach of putting preservative
into a hole whence it can slowly seep makes sense.
No it isn't on you claim that his suggestion is a good one.

No it doesn’t. It doesn’t matter how long you wait,
without pressure treatment the preservative doesn’t
soak into the wood and doesn’t get anywhere near
the outside of the post where it is in contact with
water. below the ground.
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...
I think this would work if you have the patience:-) Telephone poles are
routinely dug around and then treated with some chemical preservative.
Look up Boron as a timber preservative.
Some years ago, I noticed what appeared to be large nails hammered into
timber electricity poles at ground level. The guy I asked said he
thought they were to extend the life of the pole.
Open Reach parked in my yard a few weeks back to inspect a pole.
As far as I could see this involved digging down 6" round the post,
inspecting for rot and then treating with some chemical. I didn't stand
You seem to have a very narrow view about unusual DIY suggestions, ie if
what is being suggested was any good, we would all be doing it already -
and if it's not being done, that proves it doesn't work. Very strange.
I have in fact suggested some myself, like with how to make sliding
doors sound like Star Wars doors if that is what you want to have.
And that is true with something we have been doing for centuries
now. If the approach you propose was useful, someone would have
tried it and have noticed it works better and said something about
that with something as common as fence posts and poles.
Nothing strange about it. The obvious exception is when technology
has changed, like with drilling a couple of small holes in failed double
glazing. I have never said that that isn't worth doing and it clearly does
work when it has been tried. And I have never said that the sort of
insulation that harry has done is pointless either, even tho it is a
recent approach, now viable because of how cheap decent in insulation
has become and how expensive heating houses has become lately.

I treated the posts on my fence with (old)'Cuprinol'in holes like this;
they are still there after 30 years. The fence on the other side of the

had to be replaced twice in the same time period.
But you don’t know what would have happened if you had not done that.

But you don’t know that the posts were done the same way or with

Plenty who have not done any preservative in holes in the posts
have had their fence last for more than 30 years, including me.
