The 2022 Virtual Muscadine School
In the 2022 virtual muscadine school, we covered muscadine production and food safety topics in 16 webinars with experts from across the South.Watch all webinars for free here.Muscadine Cultivar Trial in Castle Hayne, NC
Figure 1.A variety of muscadine grapes, harveted from cultivars (September 2021) at the NC State University Horticulture Research Station in Castle Hayne, NC.
Muscadine variety/cultivar trial at the Horticultural Crops Research Station in Castle Hayne NC. The trial has two sections: One 2013 planted sections with mature muscadine cultivars (2013 planting map). And one 2021-2022 planted section with new cultivars and muscadine selections (2021-22 planting map). This trial was established in collaboration with the University of Georgia and the University of Arkansas breeding programs.

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.Muscadine Food Safety
