I prefer to cut all of my river cane at ground level and bring the majority of the shaft of cane back with me. This is for several reasons.
1) I usually cut the cane in areas I will hunt later so I do not want 6-10" shafts sticking out of the ground to impale me should I trip. (Or others for that matter.
2) By cutting them much longer than needed it gives me the chance to cut the perfect arrow out of the longer shaft at a later time when I am in my workshop.
Last word of advice, when you cut your cane, bundle them as tightly together as you can ever 6-89 inches. This will keep them from being excessively crooked after they dry. This is more important if you are drying them more rapidly than normal. I use cheap Jute twine for this purpose and works well. You can also use cheap packing tape to do the same thing. Again it needs to be tight and they will shrink some during the dring process so depending on the size of your bundle you may want to re-tighten after a week or so drying. I bundle in counts of 24. Have fun!
