My PK mat has a bunch that is abour 70% filled in and the follow on pup is at 8 ft. The main trunk is tied left and right to marine cleats mounted at the top of the fence 4x4's. Works great for wind support. When the bunch is harvested the ropes get transferred.
Using cleats with a cleat hitch knot makes it easy to add slack as the pstem gets taller.
