High Tunnel Raspberries and Blackberries

Greenhouse production of raspberries and blackberries has helped to bridge one gap in establishing all season bramble production in the Northeast. However, using this method alone to cover bramble production during mid-winter months may not be cost effective for producers, especially in the face of rapidly rising energy costs. Conversely, the same rapidly rising energy costs also provide a unique opportunity for expanding local and regional market shares over those currently held by imports. Production of high quality, locally grown and shipped raspberries and blackberries could potentially shift the market supply from imported to domestic along the Atlantic seaboard.
High tunnel bramble production offers the opportunity to bridge the remaining gaps in availability during late fall and late spring. Because tunnels offer a less expensive form of season extension than greenhouses, they appear to be an ideal production option when temperatures are not too cold.
Furthermore, high tunnels can be utilized to allow less hardy floricane-fruiting raspberries and blackberries to overwinter in climates where they would otherwise be killed.
