A coworker gave me a beautiful Ficus Tree as a housewarming gift. Currently, it is residing in our bedroom, but it doesn't seem healthy. It's been steadily loosing leaves since it came home...but that's it. It's not dry, not droopy...the leaves just keep falling off by the dozens....and it's starting to look pretty bare. I water it once a week thoroughly, it has adequate sun I believe, I'm just not sure what else I should do. :(

I'm typically not great w/ plants, but I'd like to try as I love the warmth they bring to the house....

Any suggestions?
