How to prune grape 'marquette'

Late winter or very early spring (March in most zones) while fully dormant; buds are cold-hardy but late cuts risk bleeding. Train to a high-cordon or single-curtain system. Retain 2–4 renewal canes of pencil thickness and cut to 8–12 buds each; remove all other one-year wood. Retain 2-bud renewal spurs near the trunk. In summer remove laterals crowding the fruit zone to improve airflow and ripening.

Annually. Grape 'Marquette' is a cold-hardy Minnesota hybrid grown primarily outdoors in cold climates. Like all wine grapes it fruits only on growth from one-year-old canes, so hard annual dormant pruning is essential. The vine also benefits from a final tidy-up in late summer to improve air circulation and reduce disease.
