Cattleya refusing to bloom

[Houston]

Growing conditions: Zone 9, Houston, high humidity, bright indirect light, constant air movement sitting on rack outside.

This Cattleya has had 3 new growths under my care since receiving it around September.


As you can see on the oldest growth capable of producing a bloom that the sheath looks as if it has died and aborted the bloom.



On the newest growth the sheath has done the same thing, the swelling in the pseudo bulb indicated that it may want to flower, but I have never bloomed a cat so i'm not sure what to expect.



I hope some of you Cattleya whisperer's out there find this thread.

As a side note, does anyone know of a good way to make them grow upright and try to contain its sprawl? It's turning into a monster!
