Question: would a single piece of conduit support 5 or 6 (yes! I’m cutting back! Really!) heavy tomato plants, each trained into three up-growing stalks? Yes, the right size will easily@Orangeslice13 and others who have experience with electrical conduit, any info and advice would be welcomed and gratefully appreciated!
For next year in the veg garden, I’m going to start rotating crops, due to the issues with soil-borne diseases. I trellis (or try to trellis) the tall indeterminate tomatoes, which easily grow 8’ or more. The trellis will move each year.
I’m looking at two uprights, 7-8’ tall, and a cross piece that is 14-16’ long. (Three beds are 14’ long, while the other is 16’.) The uprights would slip over rebar driven into the ground.
Question: would a single piece of conduit support 5 or 6 (yes! I’m cutting back! Really!) heavy tomato plants, each trained into three up-growing stalks? Should I add an additional upright over rebar in the center with a T-connector for more support? And what diameter of rebar and conduit would you recommend? I’m leaning toward metal, since I kind of hate PVC, and the trellis will only be up May-Sept/Oct.
The trellis would look something like this, which does have a center support:

Should I add an additional upright over rebar in the center with a T-connector for more support? Yes, 14' - 16' runs will sag especially with weight.
And what diameter of rebar and conduit would you recommend? 1/2" - 5/8" diameter rebar will work. Schedule 80 (thicker walls) 1 1/4" inside diameter is my recommendation. Easier to cut, it's lighter & can drill holes & use screws for the 90* & "T" connections
Will you be pulling the rebar out of the ground each year?
