Get Your Supplies
You will need: 6" A/C galvanized damper/1/4" all thread rod/1/4" connector nuts/hacksaw/tape measure/painter’s tape
Measure, Cut and Assemble
Measure the distance from the ground to the desired height of your plant marker. Use that measurement to cut the all thread. The end result will be 7 inches longer than your desired height. That extra length will be sunk into the ground. Mark the all thread with painter’s tape and cut with a hacksaw. Remove the extra fittings from the damper and attach the connector nut. Attach the damper and connector nut to the cut length of all thread rod.
Mark 'Em Up
Using permanent marker label the damper. Insert into the garden at the appropriate spot.
