Temperature Thresholds. According to Protabase, geraniums grow well in the temperature range of 65 to 95 degrees F during the growing season, and in the winter low temperatures between 40 to 50 degrees F, according to the A-Z Encyclopedia of Garden Plants..
The temperature to propagate geraniums is ideally above 60 degrees F. Take cuttings 3 to 4 inches in length from the growing tips of branches in September to October. This allows three to four weeks for roots to develop before the first frost. Geraniums root easily from cuttings.
