The rock concept is true. It allows the post to ride above the wet - or
simply not sit in the mud.

Another trick is to paint the end with copper cheate (sp) it is green.

But in a garden - I'd use a bare copper line under the board - might
keep out the bugs for a while as the copper leaches into the soil.

An old saying: Place a rock at the bottom of your post hole and when the rock rots away, it's time to replace your (Locust) post.
