If your primary concern is the health of the plant, a south or south eastern facing room with lots of bright light all day is ideal. I’d also suggest choosing a location free of cold drafts, away from vents or air conditioning ducts - money plants do not enjoy being buffeted by chilly air and may drop their leaves in protest. But if you’ve come this far and are interested in the mystical properties of the money tree, consider a position that takes into account the feng shui of your home. Provided the light is right, you can opt to position the money plant in areas associated with a healthy career, like a desk, or near the front door to welcome in prosperity.
