I plan to build a backyard fence this spring to contain our two 30 pound dogs. I getting conflicting advice on how to set the wooden 4x4 posts.
Some say bury the posts below the frost line (31" in Indiana) and some say 2 feet is fine. The exposed part of the posts will be 4-5' tall. Some also tell me to set the posts in concrete (especially on posts for gate) and some say just fill the holes with 6" of gravel and tamp dirt around the posts - no concrete. Some of the posts will be in a small drainage detention area too. Any advice for me? Thanks!
