Wow! That's excellent! -and on a single plant! I don't think that is common for that many spikes. Maybe even twice the normal amount. I guess it's making it up to you for last year . I might be looking into that fertilizer you're using. Looks like you have plump psudobulbs and fine looking leaves we should take note of your success!My Bulbophyllum taiwanense has about 16 flower spikes this year!! This is a huge amount for my plant. Last year I had two spikes. I'm pretty happy. My plant must be too.
