Muscadine Dormant Pruning

Every year, we hold between three and four muscadine dormant pruning workshops in the state of North Carolina. Pruning is the most essential care you need to give to a muscadine vine.

Our workshops are usually in January in Eastern NC and in February in Western NC. Each workshop will be announced on the events homepage approximately 3-4 weeks ahead of time.

Pruning and training is best learned in the field in a hands-on workshop. Therfore we highly recommend to join one of our workshops every winter if you want to learn how to prune, train and maintain a muscadine vineyard.

However, additonally to the workshops, we offer a pruning webinar online as well as written advise on how to prune a muscadine vine. Further our YouTube channel features short clips on specific pruning issues.
