Patchy Triphylla

Due to recent hard frosts, I have brought the triphylla fuchsia indoors (they don't like being too cold). Now that it is growing a little, you can probably see the problem: growth has become patchy, limited mostly to the perimeter of the plant. The withering leaves reported earlier were confined to the centre, and this tendency seems to have been stopped by watering, indicating that the core of the plant was too dry.

TWO BIRDS WITH ONE STONE
The problem has been how to water without bringing on botrytis through the subsequent cold wet conditions. So I have had to keep it dry to fight the botrytis. Growing indoors should 'kill two birds with one stone': It should allow watering, whilst controlling botrytis (due to being warmer). The only problem might be that it goes leggy. I have given it a full sun position to try to avoid this.
