Growing phals outside in Florida

[Boshia]

Hi, calling out to those who live in Florida. I live in Central Florida and just started out with a few phals. I don't know if these are cold growing or hot growing plants. What I'm looking for is your experiences with growing phals in Florida- what should I look out for, is there anything special I should keep in mind? How often do you find you have to water during certain seasons, and what potting material do you use? I have mine in a mix of mostly bark and some perlite and charcoal.
