I've had poor results trying to get shipped scapes to bloom, most of them self-abort.
I've tried planting them in the field, planting in containers, various levels of shading, and even leaving the fans sitting in a pail of nutrient-laced water. I still try though, and I've never been able to notice much difference in the plant's performance. I'm not in the cut-all-scapes-off-on-new-plants club. I've noticed that if the plant feels too stressed by an event, it will attempt to self-correct.
