Hi, so I'm not a very experienced plant owner and one of my few plants, the elephant bush, has been dropping some of it's leaves lately. It's not very old, I keep it on my desk right by a window so it can get light, and I don't water it too often just when the soil starts to get dry and occasionally a little mist in between waterings. I don't really know what's wrong or what to do so any help would be great. It's not very big so I don't think the pot is too small but maybe it needs better drainage? or different soil? Again, kinda lost and don't really know what's going on.
