I have a few large pots that contain various varieties of Colocasia - 'Illustris', 'Fontanesii', 'Coffee Cups', among others. I have a 'sun room' where I overwinter other tropicals - during winter I keep it about 55 F. My question is what is the best way to overwinter them? I want to just leave them in the pot over the winter. I would prefer not to keep them as full active plants (space is limited, I would prefer to put them pot to pot). Can I just stop watering and once dry cut them back, then start watering again in Spring? I thought about keeping them semi-active and just keep cutting them back ever few weeks or so. But will this use all there stored energy and make them less stronger in Spring? I am worried about them rotting - any thoughts would be greatly appreciated.
