Mowing, planting, mulching, and hardscape need no state license in Kentucky. Licensing starts the moment you apply pesticides — including herbicides — to the lands of another. Under KRS Chapter 217B, a business applying pesticides for others is a 'dealer' that must register with the Kentucky Department of Agriculture ($75 a year) and prove at least $1,000,000 in liability insurance or surety bond.
The person running the application business needs a pesticide operator's license ($100 a year) and each employee applying pesticides needs an applicator's license ($25 a year), each tied to a certification category earned by examination. Licenses expire at the end of each calendar year. Landscape architecture — design — is a separate licensed profession under KRS Chapter 323A.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Pesticide licensing is statewide through the Kentucky Department of Agriculture, and KRS 217B.270 bars local regulation of fertilizer and pesticides. Retaining walls, grading, and structures fall under local building permits (KRS 198B.060); local business licensing applies where the company operates.

Violating KRS Chapter 217B — including applying pesticides for hire without a license or registration — is a civil violation; willful violations are criminal.
If the bond or insurance becomes unsatisfactory and is not replaced, KDA cancels the registration and applying pesticides for hire becomes unlawful until reinstated.
