Full Breakdown

Kentucky's noxious weed framework appears at KRS Chapter 249, administered by the Kentucky Department of Agriculture and the Office of Agricultural Marketing. The Commissioner of Agriculture designates noxious weeds, including Johnsongrass, Canada thistle, and musk thistle, and may declare quarantines requiring eradication. Counties may form weed control boards under KRS 249.040 with authority to inspect, order treatment, and assess unpaid control costs against the property. The state framework targets agricultural pests rather than residential lawn aesthetics, leaving routine grass-height ordinances to local governments. Designated noxious weeds must be controlled regardless of land use.

Violations & Penalties

Noncompliance with state or county quarantine orders allows the agency to treat the land and bill the owner, with liens attaching to recover costs.

Frequently Asked Questions

Does Kentucky require landowners to remove all weeds?

Only state-designated noxious weeds under KRS Chapter 249 must be controlled. General lawn weeds and tall grass are governed by local ordinances, not state law.

What happens if I ignore a noxious weed order?

The county weed board or Department of Agriculture may treat the property and bill the owner. Unpaid costs become a lien against the real estate.
