From Minnesota High Tunnel Production Manual for Commercial Growers.
One of the goals of high tunnel fruit and vegetable production is maximizing production space in the tunnel. Trellising allows you to grow plants vertically producing more fruit or vegetables per square foot. Another advantage is keeping the fruit off the ground reducing chances of soil born diseases, damage by ground dwelling pest and allowing for clean fruit. A final advantage is harvest is easier requiring less bending to harvest the crop.
There are many options for supporting plants. There are advantages and disadvantages of each type of support and for each crop. As an example, raspberries usually are trellised on doublearmed T’s with a twine or light wire strung between the posts providing adequate support for the canes.
