Muscadine grapes are well adapted to the Coastal Plain of North Carolina, where temperatures seldom fall below 10°F. Considerable injury generally occurs where winter temperatures drop below 0°F. Muscadines have a high degree of tolerance to pests and diseases that makes the production of bunch grapes nearly impossible in eastern North Carolina. There is no other fruit with such strong personal associations for so many native North Carolinians.
Neopestalotiopsis leaf, fruit, and crown rot is an important emerging fungal disease of strawberry that can affect every part of the plant (crown, roots, leaves, fruit). The pathogen is thought to be introduced via infected planting stock. The emergence of Neopestalotiopsis, especially the aggressive forms, has resulted in significant crop loss throughout the southeastern US. This publication outlines the disease cycle and best management practices for growers.
This guide provides a comprehensive overview of strawberry production in the Southeastern United States. It covers topics like cultivars, marketing, economics, production techniques, and additional considerations such as cropping and food safety. The guide is structured into four chapters, each addressing different aspects of strawberry farming, with useful resources in the appendix.
This publication will outline sustainable management practices that are appropriate for strawberry growers in the Southeast, the benefits of these practices, and how they may be incorporated into plasticulture production systems.

Soil-less growing practices have opened up new possibilities for many specialty crops, including strawberries. US strawberry growers are facing a number of challenges that threaten the future of the industry. These include increasing labor and production costs, increased competition from imports, short production seasons, new emerging pests and diseases, extreme weather patterns and new government regulations. Soil-less production of greenhouse-grown strawberries has the potential to address some of those issues. While soil-less greenhouse strawberry production has been common for many years in a number of European and Asian countries, it has yet to become commonplace in the US. Reasons are high upfront cost as well as a general lack of technical knowledge, resulting in grower reluctance to make a transition into greenhouse strawberry production. One horticultural key for a successful soil-less strawberry production system is the choice of optimal substrate options. Therefore, the presented study evaluated the impact of six substrate blends on the growth and yield of strawberry (Fragaria x ananassa cv. Albion) in a commercial greenhouse in Eastern North Carolina. Following substrate blends were used: (1) 100% Coco Fiber; (2) 50% Canadian Peat / 50% Perlite; (3) 50% Canadian Peat / 50% Coco coir; (4) 50% Canadian Peat / 50% Wood Fiber; (5) 50% Canadian Peat / 50% Bark; (6) European Peat. Tray plants (250 cc) were grown in a modified tabletop system inside a poly-covered greenhouse with basic climate control infrastructure. The study was conducted in a randomized complete block design during the growing season 2020-2021 and repeated in 2021-2022. Our results show that strawberries grown in 50% Canadian Peat / 50 % Wood Fiber yielded similar high to 100% Coco Fiber and 100% European Peat, both grower standards. Based on the research, strawberry greenhouse production could use more cost effective, local available woodfiber and Canadian peat substrates instead of coconut coir or European peat that are sourced and shipped overseas. This option can be a more cost effective option for growers in the Southeast, considering making a shift to greenhouse strawberry production.
The predominant method for strawberry production in North Carolina and throughout the United States is annual hill plasticulture. However, growers continuously face challenges such as escalating labor and production costs, heavy pest and disease pressure, and recurrent yield losses due to extreme weather events and climate change. Transitioning to a soilless greenhouse production system (e.g. table-tops) could be an avenue to alleviate some of these challenges. However, greenhouse strawberry production in North Carolina faces a host of other challenges, one of which is the lack of knowledge on cultivar performance. To help growers better understand cultivar behavior in greenhouse conditions in NC, this study aimed to evaluate the performance of seven commonly grown cultivars (‘Albion’, ‘Brilliance’, ‘Camino Real’, ‘Fronteras’, ‘Monterey’, ‘Sensation’, ‘Sweet Charlie’) in a commercial strawberry greenhouse setting in Eastern North Carolina. The greenhouse was a multi-bay, mid tech, double poly plastic covered facility. The trial, which was planted in September 2022 and concluded in May 2023, was conducted on-farm using a randomized complete block design with four replicates per treatment. Although overall yield comparisons did not reveal any significant differences among cultivars for the season as a whole, there were notable differences during specific months of the harvest period which lasted from December through May. The two everbearing varieties in the trial, Albion and Monterey, were the earliest producers of fruit, while the standard short day varieties, Camino Real and Fronteras, had almost no early yields, but demonstrated substantial peak season production in April. Postharvest quality evaluation included pH, TA (total acidity) and Brix (soluble solids content). Although pH and TA were fairly similar over all cultivars, brix was more variable, with Sweet Charlie having the highest average brix and Brilliance having the lowest average brix.
This factsheet discusses the symptoms and treatment of catfacing, an abiotic disorder in strawberries that causes misshaped fruit.
Grapes are welcome summer treats that can be eaten fresh, processed into jellies, jams, juice or even fermented into wine. Grapes are adapted to many soil types, and can be quite long-lived. There are basically two kinds of grapes grown in North Carolina, bunch grapes and muscadine. Bunch grapes produce berries in large clusters, and grow best in the mountains and piedmont areas. In coastal plain areas, Pierce's disease kills or shortens the life expectancy of many popular bunch grapes. Muscadine grapes, exemplified by the Scuppernong variety and noted for having smaller clusters, are not affected by this disease.
This muscadine grape production guide will help the increasing number of North Carolina farmers who are considering growing and marketing this fruit as a farm diversification option.

This survey was conducted online from June 30, 2019 to July 15, 2019 to ask muscadine fresh-market growers about heir largest issues of concern. Marketing and consumer education as well as the development of extended seasons through new breeding material were among the highest ranked priorities for muscadine growers in NC.
Throughout 2020, food supply chains and market channels across the state and nation continued to be disrupted by the COVID-19 pandemic. This factsheet highlights the impact the pandemic had on specialty crop producers in North Carolina from May through July 2020 and from October through December 2020. These surveys were part of a series of surveys conducted by the Center for Environmental Farming Systems, the NC State Local Foods Program, and the NC State Department of Horticultural Science throughout 2020 to capture the impact of the COVID-19 pandemic on specialty crop producers within North Carolina.
