Step 1: Dig footing holes

Step 1: Dig footing holes to create an arbor «»
Dig each footing hole about 18-inches-wide and 24-inches-deep, or to the frost line, whichever depth is greater. Fill each hole with concrete, then insert a 42-inch-long piece of ½-inch-diameter galvanized-metal pipe. (The pipe has an outside diameter of 1 ½ inches) Leave 18-inches of pipe sticking up from the middle of the footing. Allow the concrete to cure at least 24 hours. Next, use a long, 1 ½-inch-diameter auger bit or spade bit to bore a center hole into the bottom end of a post.
