How Long Can a Grape Vine Grow

An unpruned grape vine can grow to 115 feet in length, but its fruit production is diminished when left to grow this long. Professional growers and home gardeners prune grapevines up to 90 percent each growing season to maintain fruit quality.

How big do grape vines grow?

In the wild, grapevines adhere to trees through tiny tendrils. Depending on the height of the tree, grapevines can climb 80 feet or more. Cultivated grapevines can grow up to 115 feet, according to Purdue University, if left unpruned.

Do grape vines live forever?

As grape vines age, their ability to produce fruit will begin to decline at a certain point. Most healthy vines reach the end of their viable, effective lifespan around 25 to 30 years and once a vine gets to this age the clusters of fruit become less dense and much more sparse.
