I need to put a 4x4 holding up a mailbox, into the ground. I'm going to use quikrete for this.
Now the standard is to make the hole 1/3 as deep as the height of the post above the ground. I can't do this, because of regulations about how high the USPS wants the mailbox. Given the 4x4 that I have, leaving the minimum height (41 inches) above the ground, leaves me only about 8 inches to put in the ground.
So my question is, should I make the hole for the post, very wide, or just make it narrow and deep? Remember, there will only be about 8" of post in the ground.
