Table grapes need to be vigorous with the canopy positioned for maximum sunlight absorption. A Double-T Lyre trellis is best. The Double-T trellis should have 12-gauge wires spaced at 18 inches for the drip irrigation line, 42 inches for the main wire, two cane wires at 52 inches spaced 12 to 18 inches apart, and top wires at 66 inches spaced 24 to 36 inches apart. You can prune your grapevines early each spring.
