Rangeland Weed Management - Revegetating with competitive plants

Formulating a Seed Mix

If you decide to revegetate, you’ll need to design a suitable seed mix. Typically you’ll want an aggressive, quick-establishing mix of grasses and forbs that can effectively occupy all available niches. (Do not include forbs if you plan broadcast treatments with broadleaf herbicides.) The seed mixture should be certified weed-free. Formulating an appropriate seed mix is typically based on the area’s intended use, how soon (and how well) the desired plants are likely to establish, competitiveness, soil attributes, precipitation, temperatureand elevation.

Local Extension agents, county weed district coordinators and Natural Resource Conservation Service field offices are good sources of information on the envi- ronmental and establishment requirements of seeded species, including species compatibility and avoidance of niche overlap. They can assist in formulating a seed mix. (See Appendix D, pp. 45-48)
