Answer: I think a little renovation is needed. Your soil just isn't suitable for turfgrass so I would seriously consider renting an aerator and applying some organic matter so the roots have somewhere to go for nourishment. A core aerator will remove one inch by three inch plugs from the lawn. Leave the plugs on the lawn and they will dissolve in rain or water from the sprinklers. After aerating spread a thin layer of sand or compost over the area and water it in well. The sand or compost plus the soil from the plugs will work their way down into the holes left by the plugs. You can then allow the fescue to spread and cover the holes or you can overseed your entire lawn. Either approach should improve the soil beneath the lawn and help your lawn grow lush and thick.
