As these things seem to rot at ground level and just below but not

It might be worth considering drilling a hole (1/4" to 1/2") to the depth
of the centre of the post - about 3" above the ground, and at an angle of
45 degrees. Every so often, top it up with your favourite preservative
(several fills, and allow the preservative to soak in well), then fit a
water-tight bung.

You'd think that if that was a useful approach, someone would
have tried it and found it works better than not doing that and
the word would have got out about that by now.

Presumably it doesn't work because you need to
pressure treat wood for the preservative to work.

In my experience it works very well.
