Last Year's Fuschias.

Just leave them and wait and see. Don't cut too quickly.

As long as they don't have the dreaded Vine Weevil you could get a good show again.

Last year my fuschias were rubbish and I have many.

Good luck.

I used to keep them going for a couple years at least. Kept covered from frost they usually survived the winters, this year having been quite mild they certainly would of.
Give them another month or so then if no weevils, give them some fresh compost and a trim to shape if needed.

Better to leave them as they are, just water regularly with a dilute mixture of water-soluble fertilizer and watch for pests

Ditto. But regarding the vine weevil, I seem to have lost all my heucheras to the pest. Anyone else? And what can one do?

I always keep fuchsias, cut them right back and they do come back.

Mine are overwintered in the greenhouse. They are twiggy, but just budding, so when there’s a bit more green I’ll give them a light trim and repot with fresh compost.
I often forget that they now need regular light watering.

I’ve kept a few that have been in pots and hanging baskets and they have all flowered again in fresh compost even after being outside all winter. See what you get - if nothing comes of them it’s no great loss really.
