I've had all I can take from "treated" wood posts! hi hi
(but see below).
They simply don't seem to last for a "reasonable"
length of time around here in Missouri...so I use
7' steel fencing "T" posts, pounded in with a hand-held
post driver (a heavy steel pipe, plugged at one end
with a large solid steel rod, welded in place)...then
I tie on say, a 10 foot length of 2" PVC pipe
with heavy cord, or in some cases, large hose clamps.
The pipes do not need to be guyed except for the
ends of a Beverage run. I leave the top and bottom
"open" on the pipe to discourage insects from moving in.
The inexpensive "Cell Core" type of PVC works just
fine...has a thick enough wall that is plenty stiff to
support beverage wires. It comes in 20 ft lengths
at farm supply stores but you can easily cut it with
a hack saw at the time of purchase for transport home.
No holes to dig in the ground, easy to pull up
with a tractor lift arm or bumper jack, easy to install
and 100% reusable!
Now, if one "has to" to use wood for permanent installations,
I have *heard* that the life of underground wood can be
extended by drilling a hole downward, say 45 degrees just above
ground level and squirting in a wood preservative
(such as "Penta") then inserting a cork. "Penta" will
leach out over time into surrounding soil (see below!)
and into the wood. Insect damage/"rot" usually occurs in the
first 6 inches or so below ground level so that's the
area that needs protection.
Replenish the chemical every couple of years or
so. A word of caution though..."Penta" and other wood
preservation chemicals are, in a word, "nasty" stuff and
I personally don't use it for health and environmental
damage it can cause.
