How do I stimulate den-phal spike?

[Leafmite]

If the roots are healthy, it gets good lighting, it isn't over-fertilized, and you don't move or repot it, many bloom three or four times a year. My phal-den was blooming almost constantly until it was knocked off a shelf, broke the new cane, and now it has taken a year off but I think I see some bumps forming....
