RURAL ROADSIDES BE MINDFUL of the management entity for the road and mow only with appropriate permission and safeguards. LIMIT MOWING to the amount needed to maintain vision clearance for safety or to control invasive weeds or undesirable woody encroachment. WHEN YOU MOW, mow no more than 1/3 of the roadside in a given year. DO NOT MOW MAY 1ST – June 30th or August 15th – September 30th. Mowing mid-summer allows milkweeds to sprout again and provides tender leaves for the next generation of young monarch caterpillars. DO NOT BLOW GRASS CLIPPINGS into the road. Clippings pose a safety hazard. NOTE: Interstates and state highway ROW are managed by IDOT and should not be managed by private citizens.
