Recommendations for the Rotating Cross-Arm (RCA) Trellis in Blackberry Systems

Moveable trellising systems like the rotating cross-arm trellis (RCA) have grown in popularity among blackberry growers in the Southeast to combat extreme weather impacts on blackberry production. Horticulture production extension specialist Dr. Amanda McWhirt and her team have been conducting research at the University of Arkansas Fruit Research Station in Clarksville, Arkansas studying the effects of the RCA trellis on yield, fruit quality, and labor. 

Through this research, various resources have been developed to provide information on the best management practices for blackberries on an RCA trellis system.
