Native grasses: Factors for successful stand establishment

Share Tweet Email

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 (Figure 1).

Before seeding

Before seeding, it is important to assess resources, including soil type, fertility, and current and past crop­ping uses, and how these resources affect the establish­ment of new native pasture. Producers must understand the potential challenges (existing weed problems, seed bank, and potential cropland herbicide carry-over), necessary changes in the farming operation, available equipment, seed sources, the intended use of the seeded area, costs and returns anticipated, and suitability for wildlife habitat. This information contributes to the preparation for seeding.


The first step in knowing the potential yield for haying or grazing is to understand more about the soil. Soil texture can be identified by a lab test or by searching NRCS soil survey maps, available through the NRCS Web Soil Survey (

Additionally, soil chemical properties needs to be determined. Previous cropping his­tory, particularly herbicide use, is necessary to prevent seedling damage from herbicide carryover. Seedling damage can result from long-residual herbicides, particularly those used for grass control. Short-residual herbicides are less likely to injure seedlings. Herbicides with rotation restrictions for corn or grain sorghum are an indication of potential seedling damage. Check labels for plant-back intervals and expected suppression.

The species and cultivar selected should be adapted to the field’s soil. If several different soils occur in a field, splitting the field should be considered, and changes in seedbed preparation may be required.

Seedbed preparation

A firm, weed-free seedbed is recommended. Seedbed preparation depends on climate, soils, and intended use. In most cases, clean-tilled seedbeds are preferred to establish pastures, especially where precipi­tation is greater than 32 inches per year. The seedbed is tilled as needed to destroy all weeds and leave a firm, friable seedbed. Weed control is a major require­ment for a successful stand. The use of a cultipacker or similar equipment before and/or after seeding can greatly improve the stand of grass, especially during seasons of low rainfall. This approach stores soil mois­ture but requires precipitation after seeding to ensure a successful stand.

Seeding method

Proper seeding depth is important to obtain adequate establishment of native grasses. Most seeds cannot emerge from deeper than 1/2 to 1 inch. Grass drills will handle the fluffy seed of most native grass species and ensure accurate placement, delivering the seed at a uniform rate.

Origin and quality of seed

Companies selling certified seed are required by law to inform buyers of seed quality. This allows buyers to determine the amount of seed to plant. Native grass seed quality is measured on a pure-live-seed (PLS) basis, which is calculated based on germination and purity. See details and examples at

Seeding rates

Seeding rates vary by soil, precipitation, and intended use of the seeding. For help on seeding rates and mixtures, consult the county Natural Resource Conservation Service Office, local K-State Research and Extension office, wildlife agencies, or seed dealers. An example mixture is given at

Seeding dates

Recommended planting dates are based on research, but they may be adjusted for your region based on local knowledge. For warm-season grasses, the optimum seeding date is about 2 weeks before the average last frost date and at least 6 weeks before hot, dry summer weather (Figure 2). If it is not possible, 1 month before to 3 weeks after the average last frost date may be an acceptable period for seeding. This allows the seedling 6 to 8 weeks to establish the per­manent root system before hot, dry summer weather.


In drier climates of Kansas, fertilizer and lime are not normally required for native species at seeding. Lime is suggested if the pH is below 6.0. Taking soil samples contributes to successful seeding. Consult NRCS or local K-State Research and Extension per­sonnel for local needs. Fertilizing may stimulate weed competition during the establishment phase.
