New to Neos - Potting question

[Dulcinea]

I have neos in spaghnum, we’ll potted with hole up through center. I’ve had them over a year and no blooms. They were all about 6-8’ from S and W facing windows. I’ve just moved them to a half bath with a skylight. They are not in the sun but very bright. No heat vent in that bath. The heat comes from the room it opens into. It will stay slightly cooler in winter now. Usually water when very dry, sometimes when not totally dry. The don’t bloom!
