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.
