Watermelon plants and wisteria
Told this would help the watermelons.
This is something I never heard before. Do you mean as companion plants? While I can't find any such reference, I do know that watermelon need to be in full sun, so wisteria would need to be far enough away not to shade them. In case your interested, here's some info on companion planting: https://www.gardeningknowhow.com/edible/herbs/hgen/companion-planting-in-your-herb-garden.htm
