Align with the centers of terminal posts. Now, dig the post holes (normally 6 wide and 18 to 24 deep) and set the line posts. Before concrete begins to set, adjust post height by carefully moving post up or down in footing. Top of line posts should be even with string; outside face approximately 1/4 inside.
Make sure to bury at least 1/3 of the length of the post into the ground. Also, add an additional 8 to 12 inches for gravel or rock sediment, which will provide drainage for water that seeps into the hole. Beginning with your corner imposts, dig holes, insert the posts and back fill them with dirt.
