the moss under my bonsai is turning brown. I don't know if I'm underwatering it or overwatering it. The foliage on the bonsai looks fine to me and the woman I bought it from said it needs lots of sun so that's where it's at getting lots of sun. If you could tell me what you think it'd be appreciated... Also if anyone has any ideas on styling? Can i safely remove that branch on the right? It's the thickest branch after the trunk.
