Yes Kay,
For bonsai,the main objective is to have a thick main stem which will later be the trunk. Cut it back to 6 inches and then grow it on for a couple of years just like you would for a bush fuchsia. During the summer months plant it into the garden, giving it a free-root-run is the quickest way to achieve thickening of main stem. At the end of the summer, dig it up and remove any thick tap-roots, leaving as many fine white roots as possible before you put it into a flower pot again for the winter. Even when it is in the garden you can begin to shape it, easiest way is to think of the shape of a triangle, this will give you a basic tree shape for your bonsai.
