‘Albion’ day neutral strawberries grown under low tunnels at the University of Minnesota in St. Paul are still producing. In research conducted by graduate student Heidi Anderson, picking frequency has been scaled back from peak production in September, but now good yields are still harvested once per week. And some say the berries taste sweeter with the cooler temperatures of fall! Tunnel sides are rolled down if night temperatures are expected to dip below 40 degrees F.
Several newer raspberry cultivars are performing well growing in containers under high tunnels at the South West Michigan Research and Extension Center (SWMREC) in Benton Harbor. Clone 62, Kwali and Imara are three standouts. They are productive and fruit are attractive and flavorful. These plants are being grown in a bark/peat media in 3-gallon bag pots. Container culture is expensive, but may be appealing to growers with limited space marketing high quality fruit.
Berry growers, mark your calendars now! This December, the North American Bramble Growers and North American Strawberry Growers Associations will meet in conjunction with the Great Lakes Expo in Grand Rapids, Michigan. The bramble and strawberry programs will start on Dec. 4th as part of the pre-conference events and continue through Tuesday, December 6th. Several TunnelBerries team members will be presenting their work during these education sessions. This is an excellent opportunity for beginners and seasoned growers to learn what is new in berry culture and management. For more details go to: www.glexpo.com
