I've been reading contradictory advice on this. For a 4x4 pressure treatedmailbox post, does setting it in concrete make it rot faster or slower thansetting it in the dirt? Thanks.

Embedding in concrete and dirt would be similar so faras both will hold moisture close the timber, acceleratingrot. The post will last longer if set on large gravel or stonesthat let moisture drain away from the timber.You may wish to consider also local rain/snow/ice andthe time it takes to dig a large hole for drainage or a smallhole for the post alone.

The kind that can't even let an a.h.r post just be an a.h.r. post.

It's a sickness, you know.
