Neo. falcata not doing much

[JennS]

I have one neo. falcata (my first) and one neo x vanda. The vanda cross I purchased I march, it is in spike for the third time since I got it. It grows in a plastic basket with tightly packed spaghnum. It is very happy whereas the falcata isn't as happy. I grow the on a piece of cork bark with some spaghnum around the roots, but most is decayed. The falcata finally flowered for the first time in June or July. I have had it at least three years. It has three fans, none of them have seemed to grow even a bit but have had good root activity.

Any advice on how to beef up the falcata or at least inspire the fan to do something? I fertilize a little haphazardly so its usually once a week with superthrive. So, should I change the mount or just add more spag, or should I just try to be more patient and stop expecting vanda size results
From a neo?
