Quick disclaimer: I don't know anything about plants. I don't even know what this plant is called; a friend got it for me as a gift just last week. It was purchased from a gardening store nearby, but they aren't much help. There were a few bugs in the tree, but I seem to have gotten rid of them. There is a drain hole at the bottom of the pot and a cork base to absorb any excess water. The leaves are just steadily falling off. I've been watering it once a week, making sure the soil is spongy, but not soaked. A picture is attached. I realize this isn't a whole lot of helpful info, I'll try to provide more info as requested to the best of my abilities.
