It is the only cool-season grass that can persist in many parts of the south. Large quantities of tall fescue are produced for seed in Oregon, in addition to its use as a pasture grass throughout Washington and Oregon. Tall fescue, one of the most drought-tolerant forage grasses, is also tolerant of poor drainage, alkalinity, and salinity. Primary Use Tall fescue is used widely for forage, turf, and conservation purposes. It is the predominant cool-season grass in many states, where it is used extensively in pastures.
Tall fescue produces most abundantly under irrigation and high fertility.
Tall fescue also can be used as a hay crop. When used for hay, tall fescue should be harvested when the first seed heads begin to appear. Kentucky 31 and Demeter have produced well in recent variety test evaluations. Kenhy, a ryegrass-fescue hybrid with improved palatability, has also performed well in these tests. Establishment When established, tall fescue has vigorous growth, but its seedling growth and establishment are somewhat slow.
