How to get a Chrisnetia to bloom?

[Jeff214]

I've had this Chrisnetia Green Light (Christensonia vietnamica x Neof. falcata) for a while and it's a good size. I haven't had luck with flowering, though.

I grow it outdoors (45 - 100 oF), filtered sun, with regular fertilizer and water year round. It seems happy enough. My cattleyas flower well under the same lighting conditions. Not sure if it needs L. anceps levels (direct sun) to bloom. I wasn't sure if should be withholding fertilizer or water during the cooler months to induce flowering.

Any advice would be appreciated, thanks!
