overwintering weak tubers
I have a bad habit of buying potted dahlias on clearance late in the season. I have again this year, although they were huge 5 gallon size pots & tubers may be nice. Previously, though, they often aren't & don't overwinter in my usual haphazard storage method. Can these be grown as potted house plants? I got a small bright red one that I think would be lovely if it were blooming at Christmas.
