1. Locate a spot that gets at least 4 hours of sun. I placed mine on the cross beams of a pergola I built a couple of years ago.
2. Drill pilot holes (a hole slightly smaller in diameter than the screw diameter) to make screwing in the eye hook a lot easier. Make sure the holes are the same distance as the steel cable so they hang straight down.
3. Slide the gutters through the holes and secure them with the cross clamps at your desired heights. You’ll notice I placed mesh tape (normally used for drywall joints), left over from another project, over the drainage holes to keep the soil from seeping. However, I think the holes are small enough, this step is not necessary. I did it out of habit.
4. Secure the gutter with the cross clamps and half circle steel rods.
Now you’re ready to fill it with organic potting soil and plant them with your choice of shallow rooted plants.
