I've had my snake plant for about six months now and I'm still kind of amazed at how little it asks of me! Honestly, I was worried I'd kill it because I tend to forget about watering, but it seems like that's exactly what it wants. My only confusion right now is whether the yellowing on one leaf means something's wrong or if it's just natural. Anyone else's snake plant do this?
