Dahlias flowing through winter

Has anyone every successfully kept their Dahlias flowing through winter, Obviously would have to be in a warm green house or conservatory but just wondered if I moved my pots would it be worthwhile rather than letting them die down and starting again in the spring?

    Dahlias will continue to flower if they are kept warm enough and get enough light. The trouble is the amount of space they take up. Have you got a huge heated greenhouse or conservatory?

    IMHO They need "a rest" in winter to perform best next summer.
    Any flowers you get over the winter , will be at the expense of next year's display.

  • Thanks,

    I have the space but suspected as much. A shame as they are still performing well despite the recent cold snap.

    As Hosta says, I think they need that rest, why don’t you just leave them until they’ve finished flowering, there’s no rule that says you have to cut them down whilst they are still flowering.

  • Ive put them in a cool greenhouse now with all the foilage so they should go dormant when the temp gets down. Ive leave them in the pot and take cuttings in the spring .

    Thanks
