  • Fertilization to promote grass cover
  • Prevention - maintain health of site
  • Removal - bag and dispose of plants if seeds have started to develop
  • Re-vegetation of highly disturbed sites


Mechanical

  • Burning - Cheatgrass burns readily; follow-up herbicide treatment and re-vegetation is necessary. Cheatgrass can cause increased fire risk; consult your local fire department for burning requirements and restrictions
  • Grazing - Early season grazing may help; graze before boot stage, then again 3 to 4 weeks later; animals will not graze once seed heads develop
  • Mowing - Not effective; plants will regrow and still set seed
