Hi all, I've had a Coelogyne Cristata for about 3 years, it's a good size and healthy. It has probably 4 or 5 new growths on at the moment but I am yet to get any blooms on it. I have Coelogyne massangeana and Coelogyne flaccida, both of which have bloomed the last two years. Do I have to do something different for Cristata?
