How should we overwinter a floribunda rose?

Do not fertilize your rose after late summer. Leave the last crop of blooms on to form hips, which will help stop the plant’s growth. Keep it well watered. After a couple of hard freezes, mound soil about 1 foot deep around the stalk and cut the canes back to two to four feet, tying them together to prevent them from whipping in the wind. In the spring, remove the soil carefully, as tender new growth may be starting.
