![]() Most fall-bearers will produce the best crop if canes are cut down each year and only allowed to fruit in the fall. The main crop is borne in the late summer and all on the tips of canes that emerge in the spring and grow throughout the summer. We remove twine and posts after plants have seen 2 freezes. Poly twine works well and comes in many sizes, we recommend #450 1-ply. Installation is usually done sometime in July after raspberries produce their first flowers. Monofi lament trellis wire should be considered instead of twine. ![]() Rows longer than 100’ should have pressuretreated 4” x 4” end posts. Posts should be spaced 15’ – 25’ apart along the row. The T is made by thru-bolting 12” – 18” two-by fours. You may also use wood posts and cross bars. Drill hole on each end the angle iron to secure twine. Bolt on a 12-18” piece of angle iron to create the horizontal crossbars. We suggest installing 6’-8’ long metal fence posts 1 1/2’ - 2’ into the soil. We have been successful using a T-trellis which supports 2 wires 12” apart at 3.5’ to 5’ above the ground (see diagram). A trellis keeps canes upright and fruit off the ground, makes picking far easier, reduces wind damage and maintains good aeration throughout the planting which helps with disease and Spotted Wing Drosophila control. We recommend all brambles be supported by a trellis. For more advanced trellising and pruning techniques, call us for recommendations. This will yield improved fruit quality and size, lower disease susceptibility, ease of harvest and better spraying efficiency. Correct trellising and pruning timing and technique allow for manipulation of cane numbers and growth. Trellising, training and pruning brambles are important for long term quality berries and crop productivity.
