I would like to offer a suggestion about setting posts, whether for a deck or a fence. Tautmped earth is effective but besides the effort it isn't a secure as setting a post in concrete. A concrete set post has much more holdinck fill with peg power but the problem with concrete is it takes time to set. Over time the wood shrinks leaving a small void between the post and the cement. This will fill with water rotting the end of the post.
A much better method is to hold the post plumb and back fill with pea gravel. It will flow around the post locking in in to position. As the post shrinks the pea gravel will continue compact. There never is a pocket to collect water
