With several helpers, stand up the frame and push the poles of one side into the edge of the plot, or into one of your parallel garden beds (G).

Sink the poles about a foot into the soil. Now arch the frame (it's not difficult) and insert the other side's poles into the soil, about 4 feet from the first side (H, I).

Sink these poles about a foot into the soil as well. Tamp down the earth around the pipes.
