Tammy,
It is kinda hard to tell by the picture but
it looks like something has eaten the leaves away. Is that the case or have they just been dropping? It does not look like it was planted too deep.

Mine does this about every 3 years. Keep the new sprouts coming up, and cut off the dead ones. It comes back fine.

I'm not even sure this is the "right" way to treat this plant, it's what I've been doing though. If there are no leaves except at the top of the branch, I sometimes leave it, and it gets a little straggly, but sometimes the result is kind of interesting (if you don't like these, cut them back some and see if they rejuvenate). Those branches tend to be the ones that die off eventually. Anything with no leaves, I cut to the ground, and those new shoots coming up take off.
