Establishment is the most important phase to ensure system longevity when planning the long-term use of a seeded native grass stand. Native species are slow to establish and do not compete well with other plants (weeds). For this reason, native grass pastures can take up to four years to become fully established. Because they have been selected for better establishment and forage production characteristics, use known cultivars. Species and cultivar selection, site preparation, seed quality, seed source, and seeding date must be considered to ensure the successful establishment of a native grass pasture. Planning is the key to achieving a successful stand. For all of Butler County, except the far NW Corner, Feb 15 – May 1 are acceptable seeding dates, however, March 25 – April 10 is the optimum time. The far NW corner of our falls March 1 – April 15 with the optimum time ranging from April 1 to April 20.
