Does anyone know how best to over winter a bougainvillea?
I don't have a conservatory, but wondering if it will be okay to winter up in the garage? The garage has a little window, so it would get some light. And the garage doesn't freeze, but it might drop below the 10*C (that bougainvilleas like to stay above). I just know if I leave it outside or in the greenhouse it will die, gets very cold here in the North East of England.
And I just don't think the central heating would do it any good either, any advice?
Thanks for reading, Tina
