I plan to install a wooden fence using 8-foot 4x4 posts connected to wooden panels. All of the lumber is pressure-treated.
My plan is to set the posts in holes that are about 3 feet deep (below the frost line where I live).
My question is: Do I need to pour concrete into the holes when I install the posts, or can I simply set them in the soil? And if I use concrete, should I pour the concrete into the bottom of the post hole first, let it set and then install the posts on top of it? Or do I pour the concrete around the post within the hole?
I can't find a clear answer anywhere about whether you actually need concrete in post holes.
