Help for my Christmas cactus?
I inherited a Christmas cactus from my very green-thumbed grandmother about 6 months ago. She lived in SC and had a greenhouse, but I live in NC and don't. I've kept it inside until until just a few days ago when I read it needs more humidity. It had flowers when I first received it, but now the stems are starting to drop off and I'm getting worried. Am I overwatering it (didn't realize I shouldn't water it from the top like usual plants) or what? What else should I do to keep it alive?
