Total newbie- help with a sentimental begonia
We received two potted tuberous begonias. They were used as decorations for my husband's grandfather's memorial service. Since they are sentimental I'd like to do my best to keep them alive. Should I keep them in pots, probably repotting them in something more permanent? Or would they be better in the ground? I have an area with the right exposure. But then I really don't understand all this digging up the tubers and storing them thing. I don't usually go to all that trouble with the plants I grow. If they were in pots, would I need to do anything special during the winter? How much does my zone (9, or Sunset 14) affect their growth? Thanks for the help!
