The dry summer can have caused some of the problems. If the plant looks healthy give it another chance to produce berries next year. After harvest this fall prune the canes to about 3 feet high, water well, and add some compost around the canes. During the winter months cut out all the dead brown branches. When you see new growth at the tips of the canes cut off a few inches off the tips to encourage branching.
