Use a sledgehammer to install the three pieces of rebar into the ground in your garden. We used 4’ pieces of rebar and forced them 2’ into the ground to be secure. If you have very hard or rocky soil, you may not feel the need to use such long pieces of rebar, and that is fine. The real goal is to have at least several inches of rebar threaded into the end of each PVC conduit pipe to prevent it from tipping on windy days. The rebar pieces should tilt slightly at an angle to mimic how the pieces of piping will splay to form the tripod.
