What's killing my Geranium?
My first impression of this Geranium was that it's indestructible. That's because, last September, I found it having been dumped out of its flower pot upside down in a pile leaves and it was growing. I rooted it, potted it and placed it in a sunny southern facing window where it did very well all winter long producing blossoms and lots of leaves. When spring began, the plant started to fade a little and I knew it wasn't supposed to be a direct sun kind of plant so I moved it to a north facing window.
The fading has continued. In the weeks since moving it, I've cut off about 1/3 of the leaves that were turning yellow or brown. I don't know what else to do. Am I under-watering it or over-watering? Does it need special plant food?
