this is the grove of an inlaws I can use to get some of my own. grove is about 15 years old. I would say 100' by 100' easy. most culms are around 20-25 ft tall and I am having a hard time finding smaller ones to harvest. the grove is very thick to a heavy runner I assume. cold hardy -5 easy. don't know what type it is though. any help and what to expect out of this type? I took some tiny shoots in the fall and there getting along ok this winter but Id like to get some big canes and get a good green screen started.
