Part of Bush Will Not Grow

Question

A section of the bush will not grow leaves or flowers. The stem and branches are nice and green and alive. It grows little buds in the spring and that’s it. Also, on that part of the plant, the leaves just curl up, turn kind of white color and then brown before falling off.
