So sorry to hear of the spike breaking off! I have done many times, most memorably once when I purchased a HUGE phalaenopsis with four spikes in bloom to give to my Mother for her birthday ( you know -give it to her then I take care of it -
) I entered her house, the screen door slammed behind me and two of the spikes were sheared off. The words I said cannot be repeated - mainly because I was so mad I was making most of them up......I was in a practically hysterical, foaming at the mouth ranting, fury. But as I was at my Mother's, no curse words were heard - at least not English curse words - As I say, I was making things up, so I could have been cursing up a storm in Swahili or something.
But about your Coelogyne, I know they really resent re-potting. I wish, when I first saw you post which was, prior to the present growth maturing, I had mentioned that the pot looked rather small for all the new spikes. But as I didn't, it doesn't help now does it? The Coelogyne experts will be chiming in soon which is great; I have worked with them, but never had one myself.
Just wanted to so Congrat's on the growth and blooming that you reported. Glad to hear you didn't throw it!! Be sure and post the pics!
Have a great New Year!
