Leaves Of Geranium Brought Indoors Are Turning Yellow And Have Silver Spots On Undersides

Question From: Livonia, Michigan, United States
Q: I have a geranium that was flourishing in a pot outdoors. I brought it inside and it is now developing yellow leaves that eventually turn brown. Some od these leaves have silver looking spots on the underside of the affected leaves. I water once weekly since bringing the plant indoors.

A: It's probably suffering from lack of sun. The white spots are probably mildew. Your geranium will continue to go down hill as its light source is reduced ( shorter days and sun hanging lower in the horizon, so treating for mildew is a waste of time, But if you must, a product such as Serenade would do the job and is organic and OMRI listed.
