Hi, Susan. We wonder if you are in any of the areas of the country that are experiencing record high heat at the moment. Geraniums will suffer, and leaves may turn brown, when the heat gets to be too much for them. If the browning is mostly on the lower leaves, this could mean a bacterial disease. The brown leaves could also be from over-fertilizing.
