Rooting Grapevine Cuttings from a Neighbor's Vine

My neighbor's grapevine grows through the fence. Can I root cuttings to plant elsewhere in my yard?

Easy Grape Propagation

Take 5-inch terminal cuttings, dip in rooting hormone, stick in potting media, water well, cover pot with plastic bag for humidity. Roots in ~6 weeks. Even easier: Buy a vine from a nursery—guaranteed variety, disease-free, and faster to establish. But if you want to try, grapes root readily from hardwood cuttings in late winter too.
