Eek! What kind of Fuchsia is this? It's obviously very vigorous! A lot of people are tempted to prune Fuchsia at the beginning of winter, as that is when it begins to look untidy. In relatively mild areas like yours, however, it's a lot better to wait until spring, because you can then see how far up the new growth is coming. This advice does not apply in very cold areas where all the top growth is killed by frost. In these areas it is better to cut them right back to the ground about now. Good luck. - Ian.
