My fiddle leaf fig finally stopped dropping leaves after I moved it away from the radiator and cut back watering. Turns out it hated the heat more than the inconsistent moisture. It's been stable for three months now, which for me is a win—I've killed two of these already. Anyone else found the real culprit wasn't what the internet said it would be?
