My fiddle leaf fig plant has been in our home for 9 months. She is about 6 feet tall and receives 3 cups of water every week. She lives in a north window – a bank of windows with good light. She came with a few brown spots, but it seems like more have come. Also, there is a white mildew on several of her leaves.
A friend got one at the same time, same place, and hers is also in a north window with good light. Hers is thriving!! She does not fertilize – nor do I.
What should I do???
