Will wooden posts rot in concrete?
Simply setting the posts in concrete does create a condition that will accelerate rot in the bottom of the posts. With pressure-treated posts, the rot will be slow. This allows any moisture that gets between the concrete and the bottom of the post to percolate through the gravel and away from the bottom of the post.
Can you put dry concrete in a post hole?
