Fence posts

[RoyKing]

There is a copper based treatment you spray on the posts yearly, or power coop had contractor did around the poles about 10 inches smear some copper base grease then wrap a heavy plastic around them and bury. I've used aluminumized trailer roof coat tar on post before I bury them

Here, if Locust isn't cut in the winter time when the sap is down, they won't last 5-10 years. When cut in the winter time, when sap IS down, they will last for years. I have a couple that Dad pulled from an old fence row here, from when they bought the place in 1953, and it's still solid..!! Probably have to drill it to get a fence staple in it now though.

That's an interesting observation, I'll have to try next time. Looking back at old photos, I can see that the first posts we cut were at the end of March, 2015. It was three weeks before cherries were blooming that year. Perhaps younger, thinner of the trees had already started filling with sap at that point. Judging from the photos I have, which show one pile at night that seems smaller than the pile a week later, well, I guess we made two trips to get posts. Perhaps there was also a difference over a week in temperatures and sap flow.

The next time I went to get posts a couple of years later, I am almost certain it was when there were leaves on the trees.

Drill a hole in the post where it will be below grade, and stick a length of rebar, or other steel in the hole,

The steel bar protruding from the side of the post will make it even more difficult to remove.

You could even screw a one foot length of angle steel to the post near the bottom,,
that would make removal most difficult,,

I hate concrete around posts, the concrete does seem to promote rot,,

I put a pole in the ground 4 feet deep for a pole shed.
later, I decided to remove the pole, as it was not needed,,

That pole, being 4 feet deep, was almost impossible to remove,,
I dug with a backhoe, almost half the depth, before the pole became loose,,

So, extra depth might be the answer,, also,,

Extra depth is possible, just a pain to drill. I'll give the rebar a try. Seems like drilling into the post at an angle, and sticking rebar so its like a barb would work.
