Help! I I'm a newbie to gingers and need to bring some ginger rhizomes (Heydichium and curcuma elata) in for the winter. Here in zone 8a our winters can be too wet at times, and I have lost gingers due to rot. I plan to keep them in my unheated garage until Spring. Should I cut down the stalks before frost or leave the stalks in place and let the plant go dormant (or does it have to die down in order to go dormant)? I cut down the stalks and placed the rhizomes in pots last winter, but when I planted them out they did not bloom. What do I need to do differently?
