Tropicals & Tender Perennials: Possibly a silly Colocasia question, 1 by DebinSC

How do you tell when a Colocasia goes into dormancy? I read that I should reduce watering when it does. How do I know? I have this Illustris that is blooming, even though it's been frosty the past couple of nights (mid 30s). I don't want to have it gasping for water, but I keep reading how they can rot with too much water in winter. So, do I reduce water when it gets truly cold, or when the leaves die back, or what? Thanks in advance for tolerating an EE newbie question. No laughing. :)
