I have tried many different ways to tame heirloom tomato vines throughout the years and none worked very well.
So I decided to get serious with it.
We dug deep holes, filled with cement and set pvc into them.
The we set a smaller diameter pvc into that, used connectors to build the white part of the system.
Think of it as a large 'M'. A long row along the north side with three branches running north to south.
I have room in between for other rows.
We cut 5 ft 2X4 fencing to length and used poultry staples to secure it to a scrap board. We used zip ties to hang the boards off the top support and zip ties to secure the bottom of the fence to the upright supports.
The support frame is 7 feet high with a 5 ft fence hanging on it, leaving 2 feet of open space at the bottom for working and weeding and composting.
So far I love, love, love it and it can be easily taken down and stored over the winter so as not to weaken the pvc.
We started late, so the vines were already a good size before we got them up and we still have more to hang. It should look better than it does with the vines more even spaced.
Next year it will go better, but I am still loving it.
