@rick54 Hibiscus moscheutos will die back to the ground every winter. When the tops die, you can cut them back, but it is not necessary. Leaving the dead stalks will not hurt the plant or interfere with regrowth in the spring. Most people cut them back because they don't like the looks of dead plants all winter. I looked at the weather for your area and you are still have night temps down in the 40's and some day temps only reaching the 60's that's still cold for Hibiscus growth. I didn't get good growth until temps here reach upper 60's at night and upper 70's and 80's in the day.
