Which statement describes head-trained vines?

• A. The vine is trained on a trellis with multiple spurs along trunk.
• B. Head-trained vines have no permanent cordon, and the trunk ends in a knob, or head.
• C. The trunk is permanently unwooded and grows upward.
• D. The vine train uses a permanent horizontal cordon along the trunk.

Answer: (B)

Head-trained vines are managed without a permanent cordon along the trunk. The growth is kept as a short trunk that ends in a knob, or head, from which fruiting wood regularly develops each season. This means there isn’t a long, fixed framework along the trunk to hold spurs or canes year after year; pruning focuses on maintaining that head shape and producing the next season’s fruiting wood from it. That’s why describing head-trained vines as having no permanent cordon and ending the trunk in a head fits best. The other statements describe systems with a fixed cordon or permanent training along the trunk, which is not characteristic of head-trained training.
