Phalenopsis Rebloom off old Spike

[UnstuckinTime]

Hey Orchid Board,

So here is an phalaenopsis that is blooming in my office. My office mates kept on the original spikes that were blooming last year when they purchased the plant. At the tip of each of last year's spikes, there is what appears to be a still alive growing tip. Looking closely, they're clearly alive, but growth has arrested.

I'm wondering now, is there any way to unpause them? Do you know of any natural tricks, or hormone treatments, that could unlock them and get more blossoms out of it?


Looking forward to your responses,
CJ
