I have 6 hanging baskets of geraniums that I currently have moved to hangin g in front of my garage window. The garage never quite gets down to freezi ng, but does go as low as the mid-30's once or twice a winter, and the plan ts seem to go essentially dormant until later in the Spring when they get m ore light from the longer days.
The plants are now leggy after a summer of growing/blooming without any tri mming except for dead flower stalks. Should I trim them back now and try t o root the cut-offs, or wait until mid-Spring to do the trimming and hopefu lly rooting the cut-offs?
