I live in the Pacific Northwest and it is very rainy here. I find that the problem here is that the fuchsias drown from too much water. I grow mine in large clay containers because I have dogs and they would get trampled. My method: before frost I move them in a cluster on the cement patio, cut back, mulch with leaves. I then cover them with a "planket" this keeps the frost off and does let enough water in. I've used this method for 3-4 years now and it seems to work. It is much more successful that other methods I've tried i.e. trenching, crawlspace, deck, burying with leaves.
Yes there are many ways to over winter them. The article was just a generalisation. They are in fact a lot tougher than people think. Mine are just kept in a Block in carport with no heat at all. As long as it works, that's all that matters. By the way I'm bringing out a new release next year called "My Mary-Ann". After one of my Grand daughters.
I like your "MaryAnn" I'm sure we all figure out what the best method for us is. I tried this after having them rot and then got tired of moving them from the yard into a protected area. Just wanted to post my idea, but I have used yours in the past.
