You are probably right to dig it up and pot it for the winter.With enough light it should continue to grow through the winter.Pot it in rich,fast draining soil.I would add some "Black Cow"composted cow manure to the mix.Brugs are heavy feeders.One thing to check for is spider mites.Brugs are heaven for these and they can make a plant unhealthy.I use a soap solution for these and other pests.The solution I use is here.
