Yes, ginger survive winter indoors very well and often does better inside than out in cold months. Ginger needs warmth to thrive so your heated home makes a perfect spot for it. I have kept the same plants going for five winters now with no problems at all.
Wisconsin Horticulture says to move your ginger inside when nighttime temps drop below 50°F (10°C) outside. This is the point where cold starts to stress the plant and slow growth down. The UVM Extension confirms that ginger adapts well to living inside your home all winter.
I started overwintering ginger after losing two plants to an early frost one fall. Now I watch the weather and bring pots in before temps get too low at night. A spot near a bright window works great for most homes through the winter.
Ginger dormancy happens when the plant decides to rest for winter even indoors. The leaves turn yellow and die back over a few weeks as days get shorter. This looks scary but the rhizome stays alive under the soil waiting for spring to return.
Indoor ginger winter care gets much easier once you know what to expect from your plants. Cut water way back to just once a month during dormancy while the plant rests. Too much water on sleeping roots causes rot faster than anything else will.
Keep your dormant ginger in a spot that stays between 55°F and 70°F (13°C to 21°C) all winter long. A cool room works fine as long as it never freezes or gets too hot from heating vents. I keep mine in my spare bedroom where temps stay pretty steady all season.
Some growers use grow lights to keep their ginger growing through winter instead of letting it rest. You need lights on for 12 to 14 hours a day plus warm soil temps to make this work well. I tried this one year and got green leaves all winter but smaller rhizomes at harvest time.
Watch for signs that tell you if your dormant plant is healthy or having problems inside. Firm rhizomes under the soil mean all is well even with no leaves up top. Soft mushy spots signal rot from too much water and need quick action to save the plant.
Your ginger will wake up on its own when days get longer in late winter or early spring. New green shoots push up through the soil as the plant senses more light each day. Start watering more often once you see fresh growth appear and move the pot to a sunnier spot.
