We recently were given a miniature gardenia bonsai. I've been good (I think) with the watering, keeping the growing medium wet and the pebbles on the tray beneath it. Had it about 2 weeks and, although it arrived in perfect condition, some of the leaves are starting to yellow. Does it need more light (is in a west facing window in wintery New Jersey)? Am I over or under-watering it? Does it need food?
Thanks for your help!
