My poor geranium's blooms are gone and the leaves have blackish circles on them. What have I done wrong?

I have been watering it fairly often (almost daily) and have it placed in full-to-partial sun. Am I over-watering? Can it be rescued?

Geraniums can't take frost. If the nights have been really cold, you might want to bring them inside.
Reply:A lot of Geraniums have blackish circles on them this is very common for a Geranium. But you could be over watering them I would only water them if the dirt feels dry. Most Geraniums can handle the direct sunlight have you fertilized it at all ?
Reply:Maybe you over watered them.
Reply:You may be overwatering them. Water them when the soil is dry down about 1/4 an inch, and only water on the soil. Try not to get water on the plant, especially the leaves. Rainwater won't hurt them, but tap water will.
