Why does my indoor gardenia have brown spots on the leaves?
I'm hoping somebody might have some insights on my potted gardenia. I've had her for about a year now and she's only bloomed twice. In the last six months, she's been developing brown spots on her leaves, or they turn yellow and fall off.
I spray her once a day with warm water and have a rock filled water tray under for humidity. She's near a diffused south-facing window.
I've tried feeding, not feeding, repotting, cleaning the leaves, trimming the dead ones...I'm at a loss. I've heard they like acidic soil but I don't know if this is related.
Any ideas or tips?
