We live in the Chicago suburbs. Last winter I put all our hanging baskets of geraniums in a barely warm garage, anywhere from 35 degrees up to 55 degrees. They survived and have bloomed vigorously all this summer hanging along the sides of our deck. But, the plants have become leggy and I need to do something with them. Never had geraniums before so my wife and I don't know what we should be doing for this upcoming winter.
Help please.
