Finally got my Ficus lyrata to stop dropping leaves after moving it away from the heating vent

Finally got my Ficus lyrata to stop dropping leaves after moving it away from the heating vent. I'd read everywhere that they're finicky, and I believed it—mine was basically a stick for two years. Turns out mine just needed consistent warmth without the dry blast. I'm in an arid climate so that was counterintuitive, but it's thriving now. If yours is struggling, the vent theory might be worth trying before you give up on it.
