I use 1 1/4" thinwall metal conduit (EMT) cut into 10" lengths for normal and clay soils and 12" lengths for sandy soils such as where you see the beans growing. One end is closed using a large vise to keep the tube from filling with dirt when it is driven into the ground and also wedges the plastic conduit.

This system handles 50 mph winds without any problems or damages.
I cut poplar sticks 3/4" x 3/4" x 4" (snug fit) to screw onto the 1/2" thinwall used to fasten the tops of the posts together. Then the sticks are slipped into the top of the posts. Claud
