I have 6 hanging baskets of geraniums that I currently have moved to hanging in front of my garage window. The garage never quite gets down to freezing, but does go as low as the mid-30's once or twice a winter, and the plants seem to go essentially dormant until later in the Spring when they get more light from the longer days.

The plants are now leggy after a summer of growing/blooming without any trimming except for dead flower stalks. Should I trim them back now and try to root the cut-offs, or wait until mid-Spring to do the trimming and hopefully rooting the cut-offs?
