Blackberry Trellis Systems
Standard two-wire trellis This is the most common type of trellis used for trail- ing and semi-erect blackberries. It is simple to build. Two wires (gauge size 9 or 11) are stretched between line posts set 20-24 feet apart in the row. String one wire 3 feet from the ground and the other about 5 feet from the ground. Staple wires loosely to posts to allow for contraction in cold weather. Trellises of this height require sturdy end posts, 8 feet in length, well braced, and anchored. Line posts should be about 8 feet long and 3 inches in diameter. Sink trellis posts into the ground at least 2 1/2 feet.
Managing primocanes on a two-wire trellis Primocanes of trailing and semi-erect blackberries are extremely vigorous and need to be managed throughout the summer.
Tie primocanes loosely together as they develop, and train them up through the plant to the top wire. Once they have reached the top wire, divide and tie them to the wire.
Floricanes woven to a two-wire trellis Bring the longest cane over the top wire and under the bottom wire in a spiral.
Place remaining canes parallel to this first cane until all the canes have been trained. After all canes have been tied, cut the ends so canes from adjacent plants do not overlap
The shift trellis was designed to increase productivity by concentrating all fruit on one side of the canopy, thereby minimizing berry loss to sunscald and improving fruit quality. Management of insects and diseases is easier also due to the concentration of fruit in one area of the canopy, making pesticide application much more effective.
The shift is like a hinged trellis, which allows the trellis to
move in an arc from one side of the row to the other. At
bloom, the canopy is positioned parallel to the ground to
concentrate flower development on the upper part of the
canopy. As the fruit begins to mature, the arm is moved to
120 degrees from the horizontal pre-bloom position and
