Self-pollinating and vigorous, grapevines have been known to produce excellent crops for well over 30 years. Versatile and fast growing, a grapevine can bear fruit in just 2 years. One vine requires about 8 ft. of trellis or fence, with each plant producing on average about 15 lbs. of fruit per year. All grapes are self-pollinating, and have excellent resistance to most grape diseases.
