I got this at Lowes back in May. I need some advice on how to care for it. The pot does not have a drain hole and I've contemplated drilling a hole in the bottom. I try not to over water, but I never know if or when to water it (especially since there are a few different types of plants). How often should I water and how much? Should I drill a hole in the bottom for drainage? What are some signs of over/under watering? Do I ever need to separate these plants? Can I start a new plant with leave cutting? Does it like to be misted? I keep it indoors and it get lots of light; I would like some advice on light too (does it light direct sun)? Thanks for your advice!
