Can sweet potatoes and sunchokes be planted together?

I have a huge nursery pot (used for trees) in which I want to plant sunchokes and sweet potatoes. Maybe even a passion fruit vine. I would put wood chips in the bottom and a good potting mix throughout. It would be drip irrigation. If I end up adding the passion fruit I would hope it would climb up the sunchokes and then from there on to a cattle pen arch trellis. It would have drip irrigation and face south. Thoughts?😁

Sounds good, especially the artichokes and sweet potatoes. You might want to leave out the passion fruit, unless you're growing it as an annual, because you would have to disturb its roots  to dig up the tubers of the other two. Maybe use runner beans or something for the climber. Sunchokes do make good bean poles. Good luck with your experiment.

Thanks Dan! I was worried that they might inhibit each other. I might do the pole beans. Now about watering. Currently my drip system goes every day. Is this ok? Or should I water every other day and heavy soak? Here in zone 10 in the summer everything wilts!

Okra companion plants well with okra, apparently, though I haven't tried growing, or even eating, it yet.

I typically avoid having two individuals sharing the same trophic level, or living in the same place in the soil and above the ground. Both sweet potatoes and sunchokes are grown for their tubers, and so it is easy to see how they might end up in direct competition for soil resources. Mixing a tuber crop with something grown for its fruit with a root zone that extends down deep, or that spreads into a wide net, or one that sits as a mat in the top few centimetres of soil, gives a better chance that not only will they not be competing for the same soil resources in the same places, but might also benefit eachother, as the root zone exudates of one might be the fertilizer of the other, and vice versa. One man's trash is another man's treasure, but only if they value things differently. So with humans, and also with plants.

Any place I ever put sunchokes, they won out over everything else there.  Sunchokes appear to like being a monocrop.

I've never watered sunchokes, at least not when I lived in zone 5, but I'm in zone 9b/10a now and actually just planted them as an experiment. Everyone I've talked to says they won't thrive here, but that won't deter me from trying, I brought plenty with me when I moved, red and white. In my experience, sweet potatoes and sunchokes are excellent nutrient scavengers and thrive in poor soil, so I see no problem growing them together in well amended soil, although I do agree with Chris in general about not planting multiple plants that share the same trophic zone. As far as watering goes, I couldn't say without knowing what kind of zone 10 you live in, wet or dry. Here it rains every day in the summer. So water wouldnt be an issue. But I planted mine in november, which is our dry season and they are growing well. There are still sweet potatoes growing in the nematode infested sand that I planted over a year ago and abandoned for the summer. I'm using them for slips to start new patches right now. Sometimes I just throw everything at the wall to see what sticks.
