Answer: This plant is not considered to be winter hardy in your area, so if it was planted in the ground for the winter, I am surprised it is alive! If that is what happened, you would trim off the now-dead branches and allow the new growth to replace them. If it is planted in a container, it may be that it needs more water. Although extremely drought tolerant once established, the potting mix is most likely a fast draining mix and this means you would need to water it regularly. It should not be allowed to go bone dry. Again, if the branches are dead you would trim them off. If neither of these sounds right, I would suggest you consult with your county extension and/or retailer and see if they can help you diagnose the problem more specifically.
