Hi Melissa,
I tried this with my only 2 plants of 'Tristesse' a couple of weeks ago (as you know). I had a look yesterday and there is 'something' happening. As I have two identical plants, I have one outside in full sun with all my others. And the other I have keep slightly shaded and it has had 2 good liquid feeds of high nitrogen to try to stimulate growth.
Too early to tell yet but something is growing. I cut mine as low as I dared - about 3 rings of leaves above the base? I believe if you don't cut low enough it will just cause new flower buds to form.
Good luck!
