Weed that looks like a grapevine but there's no grapes on it

[paulareds]

I don't know how far north it grows, but sounds like kudzu. If it is kudzu there is nothing that will kill it or eat it. Kudzu does have yellow flowers on it I think once a year. Google kudzu or kudzu vine and see if that's it.

Not true that "nothing will eat kudzu"

Farm animals that can eat kudzu include:

• Sheep: They can safely consume kudzu, which is rich in nutrients and protein1.
• Goats: Similar to sheep, goats also prefer kudzu over other forage options1.
• Cows: Kudzu is considered a safe and nutritious food source for cows3.
• Pigs: They can also eat kudzu, which provides a good source of nutrition
• Pretty much all of it — the leaves, flowers and roots — is edible except the vine.

Likely a male plant, they do not produce fruit. Also could not be producing due to lack of nutrients, not enough light, etc.

It looks like a wild grape vine.
