Hi Connie--nice to meet you! I love phals too. What ever the reason they are not drying out, stick your finger down in the pot, and only water when they are pretty close to dry. Be sure not to get water standing in the leaf axils. Don't see why they wouldn't thrive where you live if you don't overwater them. It's usually a mistake to water on a schedule without checking to see if your plants actually NEED it.
And yes, you may not stop acquiring phals until your window is stuffed with them (like the rest of us!). LOL
