Overwintering geraniums

I have a lot of geraniums to overwinter in an unheated greenhouse.  Last year they flowered all through the winter even though I cut them back, but became very leggy and the flowers have been quite small this summer.  This winter, should I trim off buds as and when they appear, to encourage bushy growth in the plant.

    I think I'd enjoy the flowers and then cut them back quite hard in spring to encourage new growth to carry the summer flowers (assuming you mean pelargoniums - geraniums are hardy and can be left in the ground where they'll die back for the winter and regrow in spring).

    I’ve discovered that over wintering rooted cuttings works best for me. I’m in NEEngland and used to over winter that years plants in my cold greenhouse. They all seemed to end up suffering grey mould ( Botrytis.) So I now take cuttings in late summer and pot them into 3-4 inch pots. These I overwinter on shelves against a garage window. I keep them almost dry and rotate them as they get a bit leggy.The older plants I leave in their 10 inch terracotta pots, some are kept in a plastic greenhouse with its door rolled up and others against the house wall. Again keep them dry ish. Some of these survive ok some not so good so I take Spring cuttings from them. Good luck.
