Hi I am new too keeping Bulbophyllums I have a BiColor. I got it in Oct 2016. It has not done much for me but I did give it fresh Moss and have been keeping it warmer and wetter. SO it is happy. I don't think it is happy enough to spike but I don't know.
At first I thought it was new Growth but as it got longer It looked more like a spike that my other orchids give off. But I know Bulbophyllums are different from the others I keep.
First growth I noticed.
Now this is growing too.
