I have two nice zonal geraniums and now they have dry, brown spots on their leaves that are V-shaped or round(fingernail-sized). There seems to be concentric rings inside the brown areas and the leaves are beginning to yellow. They are flowering pretty vigorously, but these spots are on many leaves and I'm getting a bit worried. What is this (it might be a bacterial infection, but i don't know)? Is there a cure? Please tell me if you know.
Thanks very much,
