Place the legs in the holes with the bottom rung 1 in. above ground level. If the top of the trellis isn't level, add gravel on the low side. Attach two 3-4 ft. lengths of 2x2 or 1x2 lumber to opposite sides of the trellis with one screw each to stabilize the trellis while you plumb it.

Fill the holes with more gravel. Pack the gravel around the posts with a 2x4. Concrete is suitable for permanent installations, but gravel allows easy relocation or removal of the trellis.
