Tall fescue is a wide-bladed clump grass commonly used in pastures.
In a lawn, the textural difference of fescue from bluegrass is obvious because of its clumps. This interruption in uniformity makes us think of fescue as a weed. Tall fescues have been the subject of much improvement and breeding. The resulting turf types make a good lawn if they comprise 100 percent of the lawn. However, when the pasture-type tall fescues invade a bluegrass lawn, you may note that the clumps are tougher and the lawn mower has difficulty cutting them.
