Q.Geranium Yellow Leaves
Why is my geranium getting yellow leaves on the bottom part of the plant? This beautiful, lush triple plant was on the deck this summer and I want to save it over the winter. It has a sunny spot to be in the house. I suspect overwatering on my part. Also, should I give it fertilizer?

Most likely it is overwatering. Geraniums like to by dry. Water only when the soil is dry to the touch.
I would recommend a slow release fertilizer, like Osmocote, for your houseplants.
