To make a fedge, in early spring simply stick the rods in the ground about 8-12" and at an angle of 45-60 degrees. Place them about 15" apart. Then go back and interplant another row of rods angled in the opposite direction, forming a diamond pattern. Then tie the joints together for stability. There are instructions on the websites listed below. Ten rods are required for a distance of approximately 7.5', when planted 15-18" apart.
