Re: minimum temp for overwintering in a pot?
Either one is good .... But the super sunny garage window might burn the plant leaves on warmer sunny days with radiant heat. So daily attendance is needed there. .... If you would be unable to check the plant daily, then op for the family room corner. As long as the temp is 50 or higher than the plant will be good and may be even grow a little. .... A third option would be to set it in a garage corner and let it go dormant (temps 32 deg to 50 deg.). It will wake-up in the spring with sun light and increasing soil temps.
