We have lots of commercial cane fields around here, and they are all started like Pokeweed described. Until this year I started my cane that way, too. Apparently, there is a "trick" that is suposed to make things a little more certain, though. Take the cane cuttings and set them upright in a shallow dish of water so that the water line comes just up over the node (you may need to keep topping it off). In about a week you should see roots starting to form and then the bud will swell and grow. You can then plant it in a pot of moist earth in the shade (water every day). I tried this with a couple 3-node cuttings of a new variety that I didn't want to lose and it worked great! They are both over 6 feet tall now and growing strong. I have not tried it on a 1-node cutting like you have, but I have seen people online who were successful with them using that method. Apparently it works so well because cane forms roots as a natural reaction to flooding.
