I've recently developed an interest in caladiums, and I'm looking to expand my collection. I know they thrive in warm, humid environments, but I live in a region with a cooler climate. Does anyone have any tips for growing caladiums indoors? Specifically, I'm curious about light requirements, watering frequency, and any tricks to keep their colors vibrant. Also, how do you prevent the leaves from drooping? Any suggestions would be greatly appreciated!
