Will a trailing geranium survive the winter?

[cardamoncoffee]

I have some trailing geraniums in containers that are still going strong and would like to keep them (in the container) until next year. If I cut them back a bit will they survive the winter? Or should I just sling them in the compost heap at the end of the season? They will be in a relatively sheltered spot.

Depends on the winter, I think.
I have had some survive some years.

@TheCountessofFitzdotterel if I cut them right back will they in theory regrow next spring?

If you cut them back and protect them from frost and mildew they could be ok. Worth a go?

In a mild winter in a sheltered spot, they might survive. The cold weather might mean you lose some branches, but a hard or prolonged freeze will probably finished them off.
If you can bring them out of the frost - even into a greenhouse or unheated conservatory they will probably be ok. Don't let them get too wet either; they won't want much water.

Potato sack and straw? I don't know let me ask my husband he is a plant head

Perhaps over winter in green house

Or should I just sling them in the compost heap at the end of the season? I wouldn't throw them away until they actually are dead. You'll never learn whether you could have kept them if you do that.

Are they what are commonly called ‘ivy geraniums’, but are actually pelargoniums? Do you still have their tags?

Take some cuttings and keep them on a windowsill so that you have some insurance against loosing the parent plant over winter. I'm on the edge of a city and lose about two thirds of my geraniums that are left out to shift for themselves.
