Timothy (Phleum pratense) is the fourth most widely grown cool-season perennial grass used in Kentucky for forage, ranking behind tall fescue, orchardgrass, and Kentucky bluegrass. It is a late maturing bunchgrass that can be used for grazing but is mainly harvested as hay, particularly for horses. Management is similar to that for other cool season-grasses. Harvesting at the proper stage of maturity (mid- to late-boot) is needed to assure high forage quality; otherwise, quality of timothy declines more rapidly than other cool-season grasses as it overmatures. In Kentucky, timothy behaves like a short-lived perennial with stands lasting for 2-3 years. Table 1 lists other College of Agriculture publications related to the establishment, management, and utilization of timothy that are available from your local county extension office.
