I'm new to gardening these kinds of plants so I don't know how to properly take care of them. My friend told me they don't need direct sunlight and watered every 4 days, so I did that and placed it on a shelf but one of the stems wilted while the other looks okay. I can't tell if it's withered because I didn't give it enough sunlight, if I over/underwatered it, or some other factor I haven't taken account of. Still wondering if it can be revived.
