Lycaste Nobuo—isn’t this thing deciduous?
 

I got a Lycaste Nobuo about 2-3 years ago and it grew some comically large leaves. Some leaves have senesced and dropped from the oldest pseudobulbs, as have most of the leaves originating from the base of each pseudobulb, but the leaves originating from the top of the three youngest pseudobulbs have just persisted for 1-3 years, and it has not bloomed under my care. From what little I have been able to find online, this hybrid is supposed to be deciduous. Should I do anything to encourage this? I gave it a bit less water over the winter. It’s in long fiber sphagnum moss, fir bark, and perlite and is near (not directly next to or under) south facing windows and grow lights. It’s my first/only Lycaste so I am not very knowledgeable on these.

I hope someone with more knowledge pipes up. But I have a deciduous(cruenta) and a hybrid Lycaste and neither needed special encouragement to bloom in my windowsill culture. The cruenta went dormant on its own, with no temperature drop or change in watering on my part, it just dropped its leaves and I cut back water in response. It may get some cooling being near a window in winter, but the dormancy did not correlate to the coldest temps here. If yours is not blooming, I wonder if it is getting enough light. I supplement my window light with led strips to mimic locations closer to the equator. I’ve also read that lycastes that are deciduous need more light than evergreen ones— but both of mine seem to appreciate pretty high light levels.
