Assuming they're hardy fuchsias I think I would leave it until spring. If you dig them up with a big enough rootball and keep them well watered any time from spring to late summer would be OK.

Hardy fuchsias are in my expereience border line hardy and moving them in late autumn or winter would I think risk losing them. Moving them in spring gives them a full growing season to bed in before the next winter hits.

I agree anchorman, oving now risks introducing frost pockets in around the roots.

I have a hardy fuchsia that looked fine until last December's snows after which it looked completely dead. My husband cut it right back to ground level and it is now 5 feet tall - don't bin them too soon if you think the winter has killed them, just prune hard and then be patient! But I agree I wouldn't plant now, unless the area you live in is warmer than average and not prone to frosts

A good tip is to plant hardy fuchsias a good 2 inches deeper in the ground than they were in the pot. This gives the growing crown an extra 2 inches of frost protection. In very cold winters you could also place a mulch of something like bark around the base of the plant. Anything to give additional frost protection.

Hardy fuchsias are quite hardy once well established and the lower stems have become woody. New small plants are not very hardy at all and I overwinter them indoors and plant them outdoors in May. After that they seem pretty tough.
