I've been growing, caring for orchids in both Virginia and now in NW Florida's panhandle for the last 15 plus yeard and have had great success with Oncidiums, Phalenopsis, Dendrobiums and Vandas. But in that whole time, I' ve only had one paphiopedilum bloom. Believe it or not it was a sale plant at a local nursey, I noticed it had a precursor flower spike and did i mention it was on sale? But it looked distressed. Never the less,the bloom flowered and I was struck, and stuck with trying to get more to bloom. I've two I've purchased from a local nursery ( on sale again) growing in fir bark and quite green and healthy looking. Except no blooms. When the temps are above 55F in the mornings here in NW FL consistently the orchids get all the humidity and filtered sunlight they need. In the winter they are houseplants and are kept in a sunny south facing window. They are watered once a week well. They are fertilized with Orchid Plus Fertilizer 20-14-13 with each watering. But in the whole time not one hint of a bloom. Thoughts? Humidity?
