Foam filled post holes

Gather App
On this one I went the full 48". I like to backfill with crushed road base, but I'll pack the black clay if it's back in the woods where I have no access. I think it's better than a ball of concrete. This drought, though, I saw some 42" posts move a little as the black soil contracted. In caliche or desert, where the soil doesn't expand or contract much, 30" braces don't move.phd2.jpgbrace.jpg
 
Believe me. It's out of necessity in the black lands. I just got an old tractor, so I'll be using an 12" auger in the future. The PHD ruins your shoulders.
 
At the other end of the fence is a hackberry twice as thick as this one on the picture that I used instead of an h-brace. Too much work to dig through the roots, too much work to chain saw, cut and burn the tree by the fence. That's what's unique.

What good is a post 3 foot deep? If you aren't 5 foot down the frost will have it out of the ground in 3 years tops. Hand digging a hole 5' deep in wet clay and rock can be a nearly impossible task (trust me I've done it).

So while your hand digging holes for corner #1, ill hook up my "fancy" auger or post pounder and have enough posts put in for an entire pasture.

I don’t have a post on the place over 3’ deep.
 
Early on i set my corners 48" deep because that's how deep my auger went. All of those corners require me to drive around with a loader and push them down 12-24" every spring even 15 years later.

A 3' deep corner could be practically out of the ground in one winter here.

The last farm I bought and am fencing is all steel pipe corners hammered 6 foot deep. Nothing has moved an inch yet.
 
Around here the only line posts that lift are either in muskeg ground or sharpened on the wrong end.
Corner braces will occasionally lift. Usually because to brace posts are too close together. Deeper is definitely better for corners.

Yup. I've seen that often. I put mine minimum 8' apart.
