Is there a "no mow" lawn in my future?

Q: My so-called lawn needs help -- it consists of clumps of grass with bare spots between, My small yard is completely fenced with a large apple tree shading much of it, so the grass gets at most 3 to 4 hours of sun a day. What do you think of "no mow" creeping red fescue?
