Over-wintering geraniums when we aren't here
We have had some really nice geraniums this year and it seems a shame that they should just be left to die after we've gone back to England for the winter. I have looked at various ways of over-wintering them, but these all seem to involve doing vital things in January and February when we aren't here. We come over just before Easter each year, all being well. In the past we have put them in the cellar (average temperature all year round, 8C) wrapped up in newspaper but they all died. Another time our neighbours took some cuttings that I had planted out but it was the year when temperatures plummeted and although the plants were in their hallway, it got so cold so quickly that they all died overnight. We have a new greenhouse - can we utilise that? All suggestions very gratefully received.
