If you’d rather build a DIY trellis, then buy the curved trellises that are available, keep reading, because I did it. In the video below I share the process with you along with my parts list and diagrams. I am using parts from TinkTube to connect all the pieces. To make the hoop (half-circle) I tried making my own jigs, and after several attempts, I wasn’t able to get a smooth bend, so I ordered a hoop bender from Bootstrap Farmer. The hoop bender created a 48″ hoop which creates a nice aesthetic atop the garden bed. Feel free to add your comments or suggestions below.

Connecting the Round Trellis To The Garden Bed
I am using parts from Tinktube (parts list below) to connect the circle halves – as well as perch and attach the top to the upright posts.
Round Trellis Parts from Tinktube
|6 x Tinktubes 1-1/16″ x 92″ Galvanized steel pipe for uprights|
|2 x 4-way cross black connector set to connect circle halves|
|4 x Tee connector black fitting set to connect other uprights|
|6 x Flat clamp black connector set to connect to garden bed|
|4 EMT adapters for a snug fit in the 4-way cross|
|1 Box Self Tapping Screws|
|Bit #2 for Robertson Screw Head|
|Additional Round Trellis Parts/Tools Purchased|
|2 x EMT Pipes (purchased locally) to make 2 – ½ circles|
|6 x Socket screws (purchased locally), you need something a wee bit longer to attach through the bed|
|Jute Trellis (purchased on Amazon)|
|Bootstrap Farmer Hoop Bender|
|Pipe Cutter from Harbor Freight|
Round Trellis Size Calculations
The overall hoop should be 150″, so 2 x 75″ sections will do. HOWEVER because we are using a connector to put the two pieces together, we have to make allowance for the connector gap, and cut the length to 73″ per section.
Final Version of the Round Trellis
With the top hoop installed you get sort of a modern slant (pun intended) on the sides. But this also will should help the beans lean more to the outside of the bed.
