I'm a bit confused after reading the Ohio Extension Bulletin titled "Raspberries for the home fruit planting". I have planted 9 black raspberry plants in a 2' x 24' raised bed garden (approximately 2.5' apart). I planted 3 Bristol, 3 Allen, and 3 Black Hawk plants.
I am trying to decide whether to support them with a trellis. In the Raspberry Bulletin, it says that a trellis can be used, but is not necessary for black raspberries. It says for black raspberries, the trellis should be 40" off the ground, but under the pruning section, it says you should head back black raspberries when they reach 24".
So my question is: If I support the raspberries with a trellis, should the trellis really be 40" off the ground? It seems like the plants would never get that tall if I headed them back to 24". If I do have a trellis, do I not head back the plants at all? Or do I head them back to a taller height?
If I don't support with a trellis, will the black raspberries stay upright and be productive?
