Give them a good home. Prune all the old canes (dead floricanes) down to the base and discard or burn. This allows room for new canes to grow. At this time, you can thin, too. In the spring, you can prune further if needed to avoid tangling or train to a trellis. Weed. Improve the soil with rich, organic matter. Fertilize in the spring (see two questions above here), and see the general care tips in the article above.
