Hi there, I recently started working at a new job, and there is a tree in the office that looks quite ill to me. I'd like to save it, but have no idea what it is and therefore can't research specific information. It's watered by a coworker every 2-4 days, and gets the most direct sunlight in the office throughout the day. Is there anything I can do differently? I'm not a plant expert, but I'm willing to learn! Thanks!
